 PURPOSE OF THIS BOOK 
 
 With the steady development of the use of fans, heaters, and air 
 washers for all industrial purposes, there has sprung up a need for a 
 book that will give in concise form the information required to properly 
 select this apparatus to meet given requirements. Not an abbreviated 
 compilation suitable for use only for a limited number of applications, 
 but one that will give to the architect or the engineer information cover- 
 ing a wide range of types and sizes adapted to every industrial need. 
 
 In the compilation of this book, the B. F. Sturtevant Company 
 have purposely avoided devoting large space to theories which are 
 probably familiar to most architects and engineers. They have instead, 
 devoted the book to actual information on performances. 
 
 The B. F. Sturtevant Company, building the most complete line of fans 
 and allied apparatus as well as the largest quantity, are in a position to 
 supply this apparatus to meet any requirements and in this book will be 
 found the principal dimensions, capacities and horse powers over a wide 
 range of service of their complete lines. 
 
 Knowing the requirements, it is an easy matter to select the type and 
 size of apparatus to fulfill them to the best advantage, and also to find 
 the principal dimensions that will aid in making the preliminary layout. 
 
 A careful reading of the explanation of tables at the beginning of each 
 section will show clearly the basis upon which the tests were made and 
 will aid greatly in selecting the proper apparatus. 
 
 It is with the desire to aid those whose work it is to select and apply 
 apparatus to various industrial problems that the B. F. Sturtevant 
 Company have gone to the great expense entailed in the publication of 
 this book. If our friends to whom this book is loaned find it of 
 assistance, then its object is fulfilled and the expense is warranted.

DEFINITIONS 
 
 Blower or Double Inlet Fan. A Centrifugal Blower is a cased fan wheel having 
 two inlets for the admission of air, one on either side and each concentric with the 
 shaft. 
 
 Exhauster or Single Inlet Fan. An Exhauster is of much the same construction as 
 a Blower, but has only one inlet, and that usually in the side farthest from the pulley, 
 engine, turbine or motor. 
 
 Overhung Wheel Fan. An Overhung Wheel Fan is one where the wheel is over- 
 hung upon the shaft, that is, where both of the bearings supporting the shaft are on 
 one side of the wheel. This is usually arranged so that the pulley runs between the 
 two bearings, and the shaft is extended through the fan casing to take the wheel. 
 Exhausters are nearly always of the Overhung Wheel type, except in the larger sizes. 
 
 Overhung Pulley Fan. An Overhung Pulley Fan is one in which there is a bearing 
 on either side of the fan wheel. The shaft being extended through one of the bearings 
 to take the pulley which is overhung upon it. Blowers and large Exhausters are 
 usually of the Overhung Pulley type. 
 
 Discharge. The discharge of a Blower or Exhauster is designated by the direction in 
 which the air is delivered from the casing; as for instance, bottom horizonal discharge 
 or upblast discharge. 
 
 Hand. The hand of a fan is that which designates upon which side of the casing the 
 pulley or other driving apparatus is located, when one is facing the outlet of the fan. 
 A right hand fan is one having the pulley, engine, turbine or motor on the right as one 
 faces the outlet, and a left hand fan is one having the pulley, engine, turbine or motor 
 on the left as one faces the outlet. An exception to the above occurs when the pulley, 
 engine, turbine or motor is placed in the inlet of a single inlet fan, in which case the 
 housing itself may be left hand, and yet the pulley, engine, turbine or motor may be 
 on the right. In such cases, which are very infrequent and usually impracticable, full 
 explanation should be given to avoid confusion. 
 
 W T ith up or down angular discharge also the hand is determined by the location of the 
 motor, turbine, pulley or engine, when the observer stands at the discharge end of the 
 fan. 
 
 Full Housing Fans. A fan with full housing has a complete scroll or casing. 
 
 Three-quarters and Seven-eighths Housing Fans. When the lower portion of the 
 scroll is dispensed with, and the fan is located upon a foundation which serves the 
 purpose of a lower part of the casing, the fan is called three-quarters housing fan, in 
 the Steel Plate type, and seven-eighths housing fan in the Multivane type. 
 
 All dimensions given in this book are for approximate use, and should not be used for 
 foundation drawings, etc. Blue Prints containing dimensions will be furnished for 
 this work.

General Explanation of Tables 
 
 The free delivery of air from every fan as actually installed is un- 
 avoidably retarded by the frictional resistance of the surfaces with 
 which the moving air is in contact and by changes in its velocity 
 and direction of motion. 
 
 In any system of conduits, the sum of all these resistances is always 
 the same when a given volume of air, or gas at a given density, is 
 flowing, and is generally called the "maintained resistance" of the 
 system. It is usually referred to in terms of the static pressure re- 
 quired to overcome the "maintained resistance," and is measured in 
 inches of water. 
 
 The "maintained resistance" of any system varies directly as the 
 square of the volume delivered through the system and directly as 
 the density of the air or gas handled. 
 
 All the capacity tables in this book give the speed and shaft horse- 
 power required to deliver any volume against any maintained resis- 
 tance within the capacity of the fan referred to. 
 
 All tables unless otherwise stated are calculated for air having a 
 density of .075 Ibs. per cubic foot, which is the density of normal 
 air at 65 F. and at sea level, or what may be called standard air. 
 The calculations are based in all cases upon the results of carefully 
 conducted tests made in our testing laboratory. The volumes were 
 determined from velocities measured, unless otherwise stated, in a 
 pipe the size of the fan outlet, by means of a pitot tube of the pin- 
 hole form. A sufficient number of readings of the velocity head were 
 taken at properly located points in the pipe to determine the average 
 velocity accurately. The static pressures were read from the static 
 side of the same pitot tube and averaged. 
 
 EFFECT OF TEMPERATURE AND ALTITUDE 
 
 The maintained resistance against which any fan at a given speed 
 will deliver a certain volume, varies directly as the density of the air 
 or gas handled, and the shaft horsepower required, also varies 
 directly as the density. 
 
 Whenever it is desired to select a fan to handle air of a greater or 
 less density than .075 Ibs. per cubic foot owing to a different temper- 
 ature, or altitude, or gas of a composition different from air, the 
 above facts must be applied in using the tables. 
 
Since the pressure varies directly with the density it follows that the 
 table pressure under which the fan is to be chosen for a given volume 
 at a given speed must bear the same ratio to the required pressure 
 as does air at "normal" density to the density of the air or gas being 
 considered. For instance, if the density of the air to be used is .5 
 that of standard air, then the pressure actually obtained will be only 
 .5 of that shown in the tables. Therefore, the fan must be picked 
 under a pressure such that .5 of it will be the pressure required, e.g., 
 if 1" is the desired pressure with air whose density is .5 of standard 
 air, the fan must be picked under the 2" column, then the actual 
 pressure will be 1". Usually the reciprocal is used in finding the 
 table pressure, that is, for the above, standard air is two times 
 heavier jthan the air under consideration and the table pressure 
 equals 1x2 equals 2". 
 
 It is obvious that the horse-power shown under the table pressure, 
 which is, of course, the horse-power for air at .075 density, will be 
 too high by the same ratio as that of the densities, because the 
 volume and speed are the same and the density, and in consequence 
 the pressure, is the only factor that has changed. Therefore, the 
 table horse-power must be multiplied by the ratio of density to obtain 
 the true horse-power. In the above example the actual horse-power 
 would be .5 of that shown in the table under the 2" pressure column. 
 
 When choosing a fan to operate at high efficiency, not only must a proper size be used but in 
 addition the fan must run at an efficient speed. As an aid to customers we have placed black 
 lines under certain volumes and horsepowers, and one of the performances above the black 
 underline in any particular column should be chosen.

 SPECIFICATIONS 
 
 General. There shall be furnished a No , design No. 2, Sturtevant Multivane 
 
 Fan. It shall be made ( single or double ) inlet, ( single or double ) 
 
 width, (right or left) hand, discharge and have (full or K) 
 
 housing. The wheel shall be not less than " diameter. The outlet shall be . . . . " 
 
 by ", the diameter of the inlet shall be ". The total height of the fan housing 
 
 shall be ", the width in direction of shaft ", and the length transverse 
 
 to shaft ". 
 
 The fan shall have a capacity of cubic feet per minute against a resistance of 
 
 " water gauge either at the inlet or at the outlet (or at both taking the sum) and 
 
 shall operate at approximately R.P.M., requiring approximately B.H.P. 
 
 Housing. The housing shall be of spiral form constructed, of steel plate strongly 
 braced, bolted and riveted to a rigid frame of angle irons. The side plates and round- 
 about sheet shall be made of No. 11 gauge for fans above 45" high. The smaller sizes 
 shall have these parts made of No. 14 gauge plate. The outlet shall be rectangular in 
 shape and consist of angle irons bolted to the housing and arranged for connection to a 
 discharge duct. The inlet shall be of cone shape and so constructed as to allow the 
 wheel to be taken out through the opening caused by the removal of the cone. In the 
 single inlet fan the side opposite the inlet shall be closed by a dished plate bolted to the 
 side of the housing. The cutoff piece shall be made of a sheet bent 180 degrees upon 
 itself and having the two ends bolted to the spiral sheet, thus leaving no edges of 
 metal which can in any way be acted upon by the air issuing from the outlet so as to 
 produce vibration, and therefore, noise at this point. 
 
 Wheel. The blades of the wheel shall be made of refined steel plate and spooned 
 with spherical depressions to efficiently handle the air. The blades shall be pressed 
 and formed while hot by means of punch and die to insure uniformity and strength in 
 the blades throughout the wheel. The hub shall be made of cast iron having cast in- 
 tegral with it and emanating from it, steel arms of "T" section. The hub shall be 
 accurately bored and fitted with keyway and set screws. The blades shall be riveted 
 at either end to annular steel plate rings or side plates. The holes through which the 
 blades are riveted to the side plates shall be punched to template, as well as the blades 
 themselves, to insure the proper position of each blade in the wheel. For diameters 
 above 46", a third annular ring shall be placed in the center of the wheel, and two hubs 
 used instead of one. The outer ends of the "T" arms emanating from the hub shall 
 be riveted to the center portion of the driving blades which shall be of thicker metal 
 than the intermediate blades. The wheel shall be absolutely symmetrical either side 
 of its center, and having no back plate can be used for either a right or left hand fan, 
 and have either single or double inlet. The wheel shall be very carefully balanced. 
 
 Bearings. The bearings shall be of the spherical self-aligning ring oiled type and 
 bolted to their support. They shall be of large diameter and built extra long to give 
 ample bearing surface. Each bearing shall be fitted with two oil rings which feed oil 
 on to the shaft from a large oil well located in the bottom part of the box. The 
 bearings shall be lined with the best quality babbit, containing upwards of 85^ tin, 
 bored and scraped to exact size. 
 
 Shaft. The shaft shall be made of steel forging and after the keyways are cut, 
 shall be accurately turned and ground.

MULTIVANE FAN DESIGN 2 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Noise. Special attention is called to the construction of the cut-off point, which, 
 considering fans in general, is the seat of most noise in the nature of a sustained 
 metallic note. Obviously any edge of metal whether directly or indirectly in the flow 
 of air can be acted upon more or less like a reed and the design of cut-off in this fan 
 avoids this condition. 
 
 The flow of air over the surfaces in a fan wheel and casing obviously produces any 
 noise which may exist ( a fan wheel revolving in a vacuum will produce no noise, as- 
 suming of course, proper mechanical balance in the wheel ) . The noise is also a 
 function of the velocity of flow. In this fan the velocity at all points as the air passes 
 through the wheel is lower than in the general run of fans of this type or as used for 
 this service, thereby operating against the production of noise. 
 
 Distribution of Work and Stresses. The spherical depressions grip the air and 
 prevent it from slipping along the blade to the side of the wheel opposite the inlet, 
 thus distributing the work along the entire length of the blade. 
 
 The driving arms of the hub being attached to the center of the driving blades, in 
 other words at a point one-half way along their axial length, produce a construction in 
 which the stresses coming upon it in operation are perfectly distributed and balanced. 
 
 Strength and Rigidity. Not only is the driving effort applied at the logical and 
 proper point but this has the added feature of holding the wheel in shape and prevent- 
 ing the blades from bowing out. Each blade is like a uniformly loaded beam when the 
 fan is in operation, that is, centrifugal force is acting alike on each element of the blade. 
 Under high speed an improperly designed wheel will first show signs of failing in the 
 bulging or bowing out of the blades at their center, which in turn moves the two side 
 plates nearer together. Without a center support construction there is nothing to stop 
 the movement of the side plates toward each other except the ability of the blade to 
 resist bending (not stretching). With the center support construction, however, the 
 driving blades are tied down at their center by their connection to the driving arms, 
 thus producing a strut or spacing piece at each point where the driving blade is located 
 which will not permit the side plates to move toward each other. The intermediate 
 blades, therefore, to bulge or bow out must either stretch themselves or pull the rivets. 
 
 Additional Strength in Larger Sizes. In sizes No. 10 and above the center 
 annulus carries out to a much greater degree the strengthening feature of tying the 
 blades at the center, thereby doing away with any chance of bowing out. That is, 
 every blade in the wheel is tied down at the center. The spider arm construction with 
 center support is considerably stronger than the usual designs of wheel supported from 
 the back. 
 
 Wearing Qualities. Barring the metal of the fan itself being subjected to violent 
 corrosion or chemical action of gases handled by the fan the brunt in the long run is 
 borne by the shaft and bearings. Therefore, for long satisfactory service a shaft 
 which is carefully turned and ground to gauge running in bearings containing a very 
 high quality babbit metal is bound to show its worth.

 EXPLANATION OF TABLES 
 
 The capacities in the following tables are measured in a pipe having 
 an area fifty percent greater than the fan outlet. The proportions 
 of these fans are such that the outlet velocities are high at normal 
 load. By expanding from the outlet to a fifty percent larger pipe a 
 part of this velocity is transformed into useful pressure, thereby 
 increasing the efficiency of the fan. 
 
 In cases where this expansion is not used a correction should be 
 made by reducing the maintained resistance from the value at the 
 head of the tables by an amount equal to forty five percent of the 
 velocity head in the fan outlet. 
 
 For further information we refer you to the general explanation of 
 tables at the front of the book.

MULTIVANE FAN DESIGN 3 
 
 SPECIFICATIONS 
 
 General. There shall be furnished a No , design No. 3, Sturtevant Multivane 
 
 Fan. It shall be made ( single or double ) inlet, ( single or double ) 
 
 width, (right or left) hand, discharge and have (full or %) 
 
 housing. The wheel shall be not less than " diameter. The outlet shall be . . . . " 
 
 by ", the diameter of the inlet shall be ". The total height of the fan housing 
 
 shall be ", the width in direction of shaft ", and the length transverse 
 
 to shaft ". 
 
 The fan shall have a capacity of cubic feet per minute against a resistance of 
 
 " water gauge either at the inlet or at the outlet (or at both taking the sum) and 
 
 shall operate at approximately R.P.M., requiring approximately B.H.P. 
 
 Housing. The housing shall be of spiral form constructed of steel plate strongly 
 braced, bolted and riveted to a rigid frame of angle irons. The side plates and round- 
 about sheet shall be made of No. 11 gauge for fans above 45" high. The smaller sizes 
 shall have these parts made of No. 14 gauge plate. The outlet shall be rectangular in 
 shape and consist of angle irons bolted to the housing and arranged for connection to a 
 discharge duct. The inlet shall be of cone shape and so constructed as to allow the 
 wheel to be taken out through the opening caused by the removal of the cone. In the 
 single inlet fan the side opposite the inlet shall be closed by a dished plate bolted to the 
 side of the housing. The cutoff piece shall be made of a sheet bent 180 degrees upon 
 itself and having the two ends bolted to the spiral sheet, thus leaving no edges of 
 metal which can in any way be acted upon by the air issuing from the outlet so as to 
 produce vibration, and therefore, noise at this point. 
 
 Wheel. The blades of the wheel shall be made of refined steel plate and spooned 
 with spherical depressions to efficiently handle the air. The blades shall be pressed 
 and formed while hot by means of punch and die to insure uniformity and strength in 
 the blades throughout the wheel. The hub shall be made of cast iron having cast in- 
 tegral with it and emanating from it, steel arms of "T" section. The hub shall be 
 accurately bored and fitted with keyway and set screws. The blades shall be riveted 
 at either end to annular steel plate rings or side plates. The holes through which the 
 blades are riveted to the side plates shall be punched to template, as well as the blades 
 themselves, to insure the proper position of each blade in the wheel. For diameters 
 above 46", a third annular ring shall be placed in the center of the wheel, and two hubs 
 used instead of one. The outer ends of the "T" arms emanating from the hub shall 
 be riveted to the center portion of the driving blades which shall be of thicker metal 
 than the intermediate blades. The wheel shall be absolutely symmetrical either side 
 of its center, and having no back plate can be used for either a right or left hand fan, 
 and have either single or double inlet. The wheel shall be very carefully balanced. 
 
 Bearings. The bearings shall be of the spherical self-aligning ring oiled type and 
 bolted to their support. They shall be of large diameter and built extra long to give 
 ample bearing surface. Each bearing shall be fitted with two oil rings which feed oil 
 on to the shaft from a large oil well located in the bottom part of the box. The 
 bearings shall be lined with the best quality babbit, containing upwards of 85$ tin, 
 bored and scraped to exact size. 
 
 Shaft. The shaft shall be made of steel forging and after the keyways are cut, 
 shall be accurately turned and ground. 
 
MULTIVANE FAN DESIGN 3 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Noise. Special attention is called to the construction of the cut-off point, which, 
 considering fans in general, is the seat of most noise in the nature of a sustained 
 metallic note. Obviously any edge of metal whether directly or indirectly in the flow 
 of air can be acted upon more or less like a reed and the design of cut-off in this fan 
 avoids this condition. 
 
 The flow of air over the surfaces in a fan wheel and casing obviously produces any 
 noise which may exist ( a fan wheel revolving in a vacuum will produce no noise, as- 
 suming of course, proper mechanical balance in the wheel ) . The noise is also a 
 function of the velocity of flow. In this fan the velocity at all points as the air passes 
 through the wheel is lower than in the general run of fans of this type or as used for 
 this service, thereby operating against the production of noise. 
 
 Distribution of Work and Stresses. The spherical depressions grip the air and 
 prevent it from slipping along the blade to the side of the wheel opposite the inlet, 
 thus distributing the work along the entire length of the blade. 
 
 The driving arms of the hub being attached to the center of the driving blades, in 
 other words at a point one-half way along their axial length, produce a construction in 
 which the stresses coming upon it in operation are perfectly distributed and balanced. 
 
 Strength and Rigidity. Not only is the driving effort applied at the logical and 
 proper point but this has the added feature of holding the wheel in shape and prevent- 
 ing the blades from bowing out. Each blade is like a uniformly loaded beam when the 
 fan is in operation, that is, centrifugal force is acting alike on each element of the blade. 
 Under high speed an improperly designed wheel will first show signs of failing in the 
 bulging or bowing out of the blades at their center, which in turn moves the two side 
 plates nearer together. Without a center support construction there is nothing to stop 
 the movement of the side plates toward each other except the ability of the blade to 
 resist bending (not stretching) . With the center support construction, however, the 
 driving blades are tied down at their center by their connection to the driving arms, 
 thus producing a strut or spacing piece at each point where the driving blade is located 
 which will not permit the side plates to move toward each other. The intermediate 
 blades, therefore, to bulge or bow out must either stretch themselves or pull the rivets. 
 
 Additional Strength in Larger Sizes. In sizes No. 10 and above the center 
 annulus carries out to a much greater degree the strengthening feature of tying the 
 blades at the center, thereby doing away with any chance of bowing out. That is, 
 every blade in the wheel is tied down at the center. The spider arm construction with 
 center support is considerably stronger than the usual designs of wheel supported from 
 the back. 
 
 Wearing Qualities. Barring the metal of the fan itself being subjected to violent 
 corrosion or chemical action of gases handled by the fan the brunt in the long run is 
 borne by the shaft and bearings. Therefore, for long satisfactory service a shaft 
 which is carefully turned and ground to gauge running in bearings containing a very 
 high quality babbit metal is bound to show its worth.

Multivane Fan Design 3 
 
 EXPLANATION OF TABLES 
 
 These fans have very large outlets compared to their capacity and 
 consequently they have low outlet velocities. The large outlet when 
 connected to a pipe of the same size produces a chimney efiect which 
 converts a large part of the velocity in the casing into useful pressure. 
 These fans should not be used without a pipe upon the outlet be- 
 cause without the pipe the conversion effect is largely lost. Neither 
 should they be used upon a pipe of less area than the outlet of the 
 fan. 
 
 Other than the above exception the general explanation of tables at 
 the front of this book applies.

 SPECIFICATIONS 
 
 General. There shall be furnished a No , Sturtevant Supervane Fan. It shall be 
 
 made ( single or double ) inlet, ( single or double ) width, (right or left) 
 
 hand, discharge and have (full or %} housing. The wheel shall be 
 
 not less than " diameter, " wide. The outlet shall be "by " , the 
 
 diameter of the inlet shall be " . The total height of the fan housing shall be " , 
 
 the width in direction of shaft " , and the length transverse of shaft " . 
 
 The fan shall have a capacity of cubic feet per minute against a resistance of 
 
 " water gauge either at the inlet or at the outlet (or at both taking the sum) and 
 
 shall operate at approximately R.P.M., requiring approximately B.H.P. 
 
 Housing. The housing shall be of spiral form constructed of steel plate and angle irons 
 strongly braced and bolted and riveted to a rigid frame of angle irons. The side plates 
 and round-about sheet shall be made of No. 11 gauge for fans above 45" high. The few 
 smaller sizes shall have these parts made of No. 14 gauge plate. The outlet shall be rect- 
 angular in shape and consist of angle irons bolted to the housing and arranged for con- 
 nection to a discharge duct. The inlet shall be of cone shape and so constructed as to 
 allow the wheel to be taken out through the opening caused by the removal of the cone. 
 In the single inlet fan the side opposite the inlet shall be closed by a dished plate bolted 
 to the side of the housing. The cutoff piece shall be made of a sheet bent 180 degrees 
 upon itself and having the two ends bolted to the spiral sheet, thus leaving no edges of 
 metal which can in any way be acted upon by the air issuing from the outlet so as to 
 produce vibration, and therefore, noise at this point. 
 
 Wheel. The blades of the wheel shall be made of refined steel plate, Both the outer 
 or discharge edge and the inner or intake edge of the blade shall have a maximum dia- 
 meter at the side plates of the wheel. The diameter of each of these edges shall 
 diminish as the center of the wheel is approached, at which point it is a minimum. 
 The outer edge of the blade shall not be in a plane through the axis but shall recede 
 gradually from either side plate in to the center of the wheel while the inner edge at 
 all points shall lie in a plane through the axis of the fan. The inner edge of the blade 
 at the center shall be relatively of very small diameter extending in almost to the hub 
 of the wheel. The blade shall be dished and curved forward in such a manner as to 
 most efficiently handle the air from the time it enters till it leaves the blade. The 
 blades shall be pressed and formed while hot by means of punch and die to insure uni- 
 formity and strength in the blades throughout the wheel. The hub shall be made of 
 cast iron having cast integral with it and emanating from it, steel arms of "T" section. 
 The hub shall be accurately bored and fitted with keyway and set screws. The blades 
 shall be riveted at either end to annular steel plate rings or side plates. The holes 
 through which the blades are riveted to the side plates shall be punched to template as 
 well as the blades themselves, to insure the proper position of each blade in the wheel. 
 The outer ends of the "T" arms emanating from the hub shall be riveted to the center 
 portion of the driving blades which shall be of thicker metal than the intermediate 
 blades. The wheel shall be absolutely symmetrical either side of its center, and having 
 no back plate can be used for either a right or left hand fan, and have either single or 
 double inlet. The wheel shall be very carefully balanced. 
 
 Bearings. The bearings shall be of the spherical self-aligning ring oiled type and 
 bolted to their support. They shall be of large diameter and built extra long to give 
 ample bearing surface. Each bearing shall be fitted with two oil rings which feed oil 
 on to the shaft from a large oil well located in the bottom part of the box. The 
 bearings shall be lined with the best quality babbit, containing upwards of 85^ tin, 
 bored and scraped to exact size. 
 
 Shaft. The shaft shall be made of steel forging and after the key ways are cut, 
 shall be accurately turned and ground. 
 
SUPER VANE FAN DESIGN 1 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Noise. Special attention is called to the construction of the cut-off point, which, 
 considering fans in general, is the seat of most noise in the nature of a sustained 
 metallic note. Obviously any edge of metal whether directly or indirectly in the flow 
 of air can be acted upon more or less like a reed and the design of cut-off in this fan 
 avoids this condition. 
 
 The flow of air over the surfaces in a fan wheel and casing obviously produces any 
 noise which may exist ( a fan wheel revolving in a vacuum will produce no noise, as- 
 suming of course, proper mechanical balance in the wheel ) . The noise is also a 
 function of the velocity of flow. In this fan the velocity at all points as the air passes 
 through the wheel is lower than in the general run of fans of this type or as used for 
 this service, thereby operating against the production of noise. 
 
 Provision for Minimizing Losses. The greater diameter of the blade at each side 
 plate does away with the loss due to air pockets, hence eddy currents, ordinarily ex- 
 isting in this portion of the blade. The projection of the intake edge of the blade deep 
 into the intake chamber picks up the air with less shock and delivers it to the outer or 
 major portion of the blade where for the most part the work on the air is done. 
 
 Distribution of Stresses. The driving arms of the hub being attached to the center 
 of the driving blades, in other words at a point one-half way along their axial length, 
 produce a construction in which the stresses coming upon it in operation are perfectly 
 distributed and balanced. 
 
 Strength and Rigidity. Not only is the driving effort applied at the logical and 
 proper point but this has the added feature of holding the wheel in shape and prevent- 
 ing the blades from bowing out. Each blade is like a uniformly loaded beam when the 
 fan is in operation, that is, centrifugal force is acting alike on each element of the blade. 
 Under high speed an improperly designed wheel will first show signs of failing in the 
 bulging or bowing out of the blades at their center, which in turn moves the two side 
 plates nearer together. Without a center support construction there is nothing to stop 
 the movement of the side plates toward each other except the ability of the blade to 
 resist bending ( not stretching ) . With the center support construction, however, the 
 driving blades are tied down at their center by their connection to the driving arms, 
 thus producing a strut or spacing piece at each point where the driving blade is located 
 which will not permit the side plates to move toward each other. The intermediate 
 blades, therefore, to bulge or bow out must either stretch themselves or pull the rivets. 
 The spider arm construction with center support is considerably stronger than the 
 usual designs of wheel supported from the back. 
 
 Wearing Qualities. Barring the metal of the fan itself being subjected to violent 
 corrosion or chemical action of gases handled by the fan the brunt in the long run is 
 borne by the shaft and bearings. Therefore, for long satisfactory service a shaft 
 which is carefully turned and ground to gauge running in bearings containing a very 
 high quality babbit metal is bound .to show its worth.

TURBO VANE FAN DESIGN 1 
 
 SPECIFICATIONS 
 
 General. There shall be furnished a No , Sturtevant Turbovane Fan. It shall be 
 
 made (single or double) ,. inlet, (single or double) width, (right or left) 
 
 hand, discharge and have (full or %) housing. The wheel shall be 
 
 not less than " diameter, " wide. The outlet shall be "by " , the 
 
 diameter of the inlet shall be " . The total height of the fan housing shall be " , 
 
 the width in direction of shaft . " , and the length transverse of shaft " . 
 
 The fan shall have a capacity, of cubic feet per minute against a resistance of 
 
 " water gauge either at the inlet or at the outlet (or at both taking the sum) and 
 
 shall operate at approximately R.P.M., requiring approximately B.H.P. 
 
 Housing. The housing shall be of spiral form constructed of steel plate strongly braced, 
 bolted and riveted to a rigid frame of angle irons. The side plates and round-about 
 sheet shall be made of No. 11 gauge plate. The outlet shall be rectangular in shape and 
 consist of angle irons bolted to the housing and arranged for connection to a discharge 
 duct. The inlet shall be of cone shape and so constructed as to allow the wheel to be 
 taken out through the opening caused by the removal of the cone. The cutoff piece 
 shall be made of a sheet bent 180 degrees upon itself and having the two ends bolted 
 to the spiral sheet, thus leaving no edges of metal which can in any way be acted upon 
 by the air issuing from the outlet so as to produce vibration, and therefore, noise at 
 this point. 
 
 Wheel. The blades of the wheel shall be made of refined steel plate, The outer or 
 discharge edge of the blade shall be parallel with the axis of the fan. The inner or 
 intake edge shall be of greatest diameter at the inlet of the wheel and decrease in 
 diameter as the back plate or hub is approached, thus producing a blade of greater 
 depth at the back of the wheel. The blades shall be curved with their convex surface 
 moving forward in rotation, and be of such shape that about two thirds of the depth 
 of the blade from the outer edge in toward the center is formed in the curve of an 
 involute of a circle. The remaining portion shall be formed in the arc of a circle. 
 The blade curvature shall be such as allows the fan to handle the air very efficiently 
 and at a relatively high peripheral speed compared with the pressure produced. The 
 hub shall be made of a solid steel forging riveted to the driving disc and accurately 
 bored and fitted with keyway and set screws. The blades shall be riveted at the end 
 nearest the fan inlet to an annular steel plate ring or side plate, and at the end 
 farthest from the fan inlet to a solid and extra heavy driving disc. The holes through 
 which the blades are riveted to the side plates shall be punched to template as well as 
 the blades themselves to insure the proper position of each blade in the wheel. 
 Equally spaced along the axial length of the outer or discharge edge of the blades shall 
 be placed two or more annular steel plate rings which add strength and rigidity to the 
 wheel. The wheels shall be very carefully balanced. 
 
 Bearings. The bearings shall be of the oil tight, dust proof pedestal type, and by 
 means of a spherical seat made self aligning. Each bearing shall be fitted with two oil 
 rings which feed oil on to the shaft from a large oil well located in the bottom of the 
 box. They shall be of large diameter and extra long to give ample bearing surface. 
 Each bearing shall be fitted with oil throwing collars and oil baffles also with a leather 
 gasket around the shaft and at the outboard end which absolutely prevents oil getting 
 out of the bearing or dust getting into it. A small glass window shall be provided 
 which shows the supply of oil in the bearing. The bearing shall be very rugged and 
 heavily built for high speed duty, and lined with the best quality babbit containing 
 upwards of 85^ tin. The bearings shall be carefully bored and scraped to exact size. 
 
 Shaft. The shaft shall be made of steel forging and after the keyways are cut, 
 shall be accurately turned and ground.

TURBO VANE FAN -DESIGN 1 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Noise. Special attention is called to the construction of the cut-off point, which, 
 considering fans in general, is the seat of most noise in the nature of a sustained 
 metallic note. Obviously, any edge of metal whether directly or indirectly in the flow 
 of air can be acted upon more or less like a reed and the design of cut-off in this fan 
 avoids this condition. 
 
 The flow of air over the surfaces in a fan wheeLand casing obviously produces any 
 noise which may exist ( a fan wheel revolving in a vacuum will produce no noise, as- 
 suming of course, proper mechanical balance in the wheel ) . The noise is also a 
 function of the velocity of flow. In this fan the velocity at all points as the air passes 
 through the wheel is lower than in the general run of fans of this type or as used for 
 this service, thereby operating against the production of noise. 
 
 Provision for Minimizing Losses. The involute curve of the blade is not carried 
 all the way in to the hub. The change of the curve in near the hub to the arc of a 
 circle increases the port area at this point and also produces a blade shape which is 
 more effective in starting the air through the wheel. By virtue of the involute form 
 of the major part of the blade, the length of a normal from any blade to the adjacent 
 blade will be constant at all points, thereby giving equal area to the passages through 
 the blades and greatly lessening the losses due to eddy currents. 
 
 Distortion. The heavy annular steel plate rings closely spaced along the outer edge 
 of the blades prevent them from bowing out at high speed and also equalize the 
 discharge of air along the axial length of the blade. 
 
 Strength and Rigidity. The back plate, inlet side plate, intermediate steel rings, 
 blades and hub are all made exceptionally heavy and assembled by the unsparing use 
 of heavy rivets. This taken with the general design and proportion of the parts 
 combines to produce a rigid and strong construction. 
 
 Wearing Qualities. Barring the metal of the fan itself being subjected to violent 
 corrosion or chemical action of gases handled by the fan the brunt in the long run is 
 borne by the shaft and bearings. Therefore, for long satisfactory service a shaft 
 which is carefully turned and ground to gauge running in bearings containing a very 
 high quality babbit metal is bound to show its worth.

STEEL PLATE FAN -DESIGN 1 
 
 SPECIFICATIONS 
 
 Furnish and erect a Sturtevant steel plate fan, housed; 
 
 discharge; hand; inlet; overhung . ; capable of deliver- 
 ing cubic feet of air per minute against a static pressure of inches, 
 
 when running at R. P. M. and requiring not more than H. P. 
 
 The fan shall be inches wide, with its outlet inches by 
 
 inches and its inlet inches diameter. 
 
 Housing. The fan shall be constructed with its housing side sheets of 
 
 gauge, its roundabout or scroll sheet of gauge. The roundabout sheet 
 
 shall be secured to the scroll angles by tap bolts of ample size spaced 5 inches on 
 
 centers. Scroll angles shall be ...... inches x inches x inches. 
 
 The sheets used in the housing shall be the best grade of blue annealed steel 
 plate. Housing shall be substantially braced by angle iron stiffeners and shall be 
 built upon an angle iron base of ample strength to give the required rigidity. 
 
 Wheel. The blast wheel shall be inches in diameter, of the side plate 
 
 type containing floats of gauge, with annular side plates of 
 
 gauge. The floats shall be strongly riveted to steel T-arms inches x 
 
 inches x inches, firmly cast into a hub spider of ca\st iron. 
 
 (In the smaller size wheels one spider only is used while in larger wheels 
 two or more spiders are used as necessary.) 
 
 The wheel shall be given -a careful balance during and after assembly to insure 
 vibrationless operation. 
 
 Shaft. The shaft shall be inches in diameter of best open hearth steel 
 
 turned and ground to exact size. 
 
 Bearings. The bearings shall be cast iron, split in a plane coincident with the 
 
 center of the shaft, and lined with Sturtevant White Metal. They shall be carried 
 
 in chairs so as to be self aligning. 
 
 Oiling shall be accomplished by means of brush oilers sunk in wells and held 
 
 against the bottom of the shaft by spiral springs. This, combined with capillary 
 
 attraction, insures a copious supply of oil being supplied at the right point. 
 
 Where the fans are to be used for the handling of hot gases, bearings shall be 
 
 furnished containing cored passages with outlets tapped for pipe connections so 
 
 that effective water circulation may be secured. 
 
 In the case of large fans, pillow block type bearings shall be furnished in place of 
 
 the chair box type.

STEEL PLATE FAN DESIGN 1 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Wheel. On account of the higher periph- 
 eral speeds of the larger sizes, greater 
 strength is necessary than in the smaller 
 sizes. For this reason steel T-arms are cast 
 into the hub rather than making the spider 
 of one casting. 
 
 Bearings. The brush oiling arrangement has 
 proved itself extremely satisfactory in serv- 
 ice. Ring oil bearings, however, will be sup- 
 plied if specified.

STEEL PLATE FAN DESIGN 2 
 
 SPECIFICATIONS 
 
 There shall be furnished a No Design 2, Sturtevant Steel Plate Fan. 
 
 It shall be made (single or double) inlet, (single or double) width, 
 
 (right or left) hand, discharge, and three-quarter housing. The 
 
 wheel shall be not less than inches diameter, inches wide. The outlet 
 
 shall be inches x inches. The diameter of the inlet shall be 
 
 inches. The total height of the fan housing shall be inches. The width in 
 
 direction of the shaft inches, and the length transverse to shaft inches. 
 
 The fan shall have a capacity of cubic feet per minute against a resistance of 
 
 inches water gauge either at the inlet or at the outlet (or at both taking 
 
 the sum) and shall operate at approximately R. P. M. requiring approxi- 
 mately B. H. P. 
 
 Housing. The housing shall be of spiral form constructed of steel plate strongly 
 braced, bolted and riveted to a rigid frame of angle irons. The outlet shall be rec- 
 tangular in shape and shall consist of angle irons bolted to the housing and arranged 
 for connection to a discharge duct. 
 
 Wheels. The blades and side plate of the wheel shall be refined steel plate. 
 The side plate shall be reinforced around the inlet, and periphery with reinforcing 
 rings. The outer edges of all blades shall be reinforced with angle irons. Both 
 blades and side plates shall be punched to templates to insure accuracy. To give 
 proper strength the blades shall be attached to the side plates by means of angle 
 irons. Single width wheels shall have two spiders; and double width wheels, four 
 spiders. The spiders shall consist of steel T-arms cast into the hub. Hubs shall 
 be accurately bored and fitted with key ways and set screws. The complete wheel 
 shall be supported from two pedestal type bearings entirely independent of the fan 
 housing. 
 
 Bearings. The bearings shall be of rigid type, and to insure an ample supply of 
 oil to the surfaces, shall be provided with three brass rings and a carefully grooved 
 cap. To prevent oil from escaping from the ends of the bearings and to return it to 
 the reservoir, both upper and lower boxes shall be provided with suitable oil 
 grooves. A sight oil gauge shall be located in the lower half of the bearing to in- 
 dicate the height of the oil in the reservoir. An overflow to prevent overfilling 
 shall also be provided. The bearing shall be designed with water passages so that 
 cooling water may be circulated when necessary. 
 
 Shaft. The shaft shall be made from a steel forging turned, splined, and ground 
 to exact finish.

STEEL PLATE FAN DESIGN 2 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Noise. These fans are designed primarily for the slower speeds and therefore 
 have comparatively large diameter wheels. This makes it possible to ob- 
 tain the necessary tip speed to develop the desired pressures without using 
 excessive rotative speeds. Also, on accounf of the peculiar construction of 
 the fan wheel, the air velocities through the fan are low and uniform. This 
 slow rotative speed, combined with the low air velocities, results in prac- 
 tically noiseless operation under ordinary conditions. 
 
 Structural Design. The satisfactory operation of a fan, from the stand- 
 point of strength and freedom from distortion, is determined entirely by 
 the design of the fan wheel and of the bearings since the construction of the 
 housing is comparatively simple and means only the proper distribution of 
 material to resist the air pressure within the casing. In this fan wheel all 
 of the principal members are radial, are of simple design, and are therefore 
 best suited to resist the stresses tending to wreck or distort the fan. The 
 fan blades are flat and are supported on at least two spiders properly lo- 
 cated on the float so as to equalize the loading on the float. The floats are 
 also reinforced at the tip so as to prevent distortion at this point. 
 
 The spiders are built up of steel T-arms cast into heavy semi-steel hubs and 
 are carefully fitted and keyed to the fan shaft. The spiders are secured in 
 proper position by steel side plates on the sides of the floats. These side 
 plates are secured to the floats by rolled steel angles and are further rein- 
 forced by steel bands at both the inside and outside diameters. After the 
 wheel has been assembled, it is carefully balanced to insure against vibra- 
 tion when in operation. Throughout the construction of this wheel hot 
 riveting is used exclusively, thereby insuring the complete filling of all holes 
 and preventing the movement of any of the parts with respect to one 
 another. 
 
 The bearings used in connection with this fan are of heavy, rigid, ring-oiling 
 type and are mounted on cast-iron pedestals which are set independently 
 of the fan housing. This insures a secure bearing for the fan wheel and 
 prevents any vibration which might be caused by connection to the fan 
 casing. The bearing pedestals are made as low as permissible to obviate 
 any possibility of vibration which is usually incidental to high supports. 
 The bearings are lined with the highest grade babbitt bearing metal and are 
 scraped to exactly fit the shaft which insures perfect operation at the start 
 and makes it unnecessary to run the bearings into shape.

 SPECIFICATIONS 
 
 There shall be furnished a inch, Design 1 Sturtevant 
 
 Steel Plate Planing Mill Exhauster to be hand, 
 
 discharge, with pulley inches in diameter by inches 
 
 face. The blast wheel shall be inches in diameter con- 
 taining floats of gauge. The floats shall be securely riveted 
 
 to steel T-arms cast into the hub. 
 
 The housing shall have side sheets of gauge and a 
 
 roundabout sheet of gauge. The roundabout sheet is to 
 
 be secured to the scroll angle by tap bolts ^g-inch, and spaced 
 five inches on centers. The inlet shall be inches in diam- 
 eter. The outlets are cylindrical and are cast on fans 30 to 80 
 inches inclusive except the down blast. In the down blast fan 
 the outlet is part of the base casting. In sizes 90 to 100 inches 
 fans the outlets are rectangular and built of angle iron. The 
 cut-off piece shall be made of a sheet so built and so attached 
 to the spiral sheet as to limit its vibration and therefore reduce 
 noise. 
 
 Shaft. The shaft shall be made of steel forging and after the 
 key ways are cut, shall be accurately turned and ground. 
 
 Bearings. The bearing shall be lined with the best quality 
 babbitt, containing upwards of 85 per cent, tin, bored and scraped 
 to size.

 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Wearing Qualities. On account of the severe 
 service to which Planing Mill Exhausters are 
 subjected, the casing and wheel of this fan are 
 of exceptionally heavy gauge 'so as to give 
 many years of satisfactory service. Further- 
 more a great deal depends upon the shaft and 
 bearings, and a shaft which is carefully turned 
 and ground to gauge, and which runs in bear- 
 ings containing a very high quality babbitt 
 metal, is bound to show its worth.

 SPECIFICATIONS 
 
 Contractor shall furnish one Sturtevant No Design 6, 
 
 Slow Speed Low Power Exhauster. It shall have an inlet 
 
 inches in diameter, an outlet inches x inches. It shall 
 
 be convertible and reversible as to hand and discharge. It shall 
 
 contain a blast wheel inches in diameter, comprising eighteen 
 
 floats each carried on a steel T-arm cast into a central "hub, these 
 blades to be tilted forwardly in the direction of rotation at their 
 outer edges. The blades shall be connected only at their rear or 
 edges most remote from the fan inlet, with an annular back plate. 
 The floats shall be made of No gauge. 
 
 Housing. The housing shall be of the convertible and reversible 
 type made up of steel side sheets secured to cast-iron inlet and cone 
 side plates by tap bolts threaded into an annular ring riveted to the 
 steel side sheet. 
 
 The roundabout or scroll sheet shall be secured to the scroll angles 
 by bolts so as to be easily replaced if necessary. The scroll angles 
 shall be riveted to the outer side of the side sheets. Rivets and bolts 
 shall be spaced either 5 inches or 2^ inches on centers as may be 
 most desirable for the work in question. 
 
 Hanger. The hanger shall be of grey iron fastened to the cone side 
 plate by tap bolts and of the design shown in the illustration here- 
 with. It shall be machined at the top to receive the bearings. 
 
 Bearings. The bearings shall consist of a cast-iron housing which in 
 itself forms an oil reservoir and mounted within which are split 
 sleeves lined with the best grade of Sturtevant white metal. These 
 sleeves shall be mounted in a spherical seat so as to be self-aligning 
 in all directions. Oiling shall be by two oil rings dipping into the 
 reservoir. Combination thrust and oil wiper collars shall be provided 
 for both ends of each bearing. Bearing housings shall be recessed 
 at either end and fitted with felt washers. Sight glasses shall be 
 inserted in the bearing housings. The filler cap shall be so located 
 as to prevent an excess of oil being carried in the reservoir. The 
 bearing housing shall be machined where it bolts to the hanger and 
 shall be secured thereto by two bolts of ample size.

 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Design 6, Slow Speed Low Power Exhauster is the most efficient fan 
 of its type on the market. It is designed for very large capacity and 
 relatively low rotative speed. It is unique in that it occupies less space 
 for a given volumetric capacity than any other fan generally used for 
 the same class of work. 
 
 Housing. The Convertible and Reversible feature enables the fan 
 to be changed to any hand or discharge by removing a few bolts, 
 turning the casing around and replacing the bolts. 
 
 Hanger. The hanger is "low-cut" so that a large pulley can be 
 used if desired. This hanger also permits the use of a belt coming up 
 from below at a sharp angle.

Slow Speed Low Power Planing Mill 
 Exhauster Design 6 
 
 EXPLANATION OF TABLES 
 
 The capacities of these fans are measured in a pipe the size of the 
 fan inlet and upon the inlet side of the fan, with outlet also con- 
 nected to a pipe of the same size by a taper transformation piece. 
 
 The tables are made upon this basis because fans used for conveying 
 are usually piped in this manner. 
 
 Other than the above the information contained in the general 
 explanation of tables shown at the front of this book applies.

EXTRA HEAVY GAS BLOWER DESIGN 4 
 
 SPECIFICATIONS 
 
 General. There shall be furnished a number Design 4 Sturtevant 
 
 Extra Heavy Gas Blower which shall be made double inlet, single width 
 
 hand discharge and have full housing. Blower shall be supplied with 
 
 expanded outlet inches diameter at the discharge end. Total height of 
 
 fan housing shall be approximately inches; width of fan in the direction of 
 
 the shaft approximately inches; length transverse to the shaft approxi- 
 mately inches. Blow r er shall have capacity of cubic feet of free 
 
 air per minute against resistance of inches water gauge at the outlet when 
 
 air is supplied freely to the inlet, and it shall operate at approximately 
 
 R. P. M., requiring approximately B. H. P. 
 
 Housing. The housing shall be of spiral form constructed of cast iron and made 
 in two halves, flanged and securely bolted together. These shall be split in 
 a plane at right angles to the shaft. Housing shall be reinforced by heavy 
 strengthening ribs running from the centre flange to circular reinforcing ribs 
 concentric with the inlets. Housing shall be convertible and drilled so that the 
 fan can be arranged for in any one of the eight different discharges and for either 
 right or left hand. 
 
 Bearings. The bearings shall be of the spherical seated self-aligning type pro- 
 vided with split bearing sleeves of suitable length and size to give ample bearing 
 support. Bearing sleeves shall be mounted in oil-tight and dust-tight housing, 
 and provided with suitable sight gauge for determining the oil level. Bearings 
 shall be thoroughly and continuously lubricated by means of oil rings. Bearings 
 shall be provided with thrust collars which also act as oil throwers to catch and 
 return to the oil reservoir any oil tending to creep along the shaft. Bearings 
 shall be lined with best quality babbitt metal, containing upwards of 85 per cent, 
 tin, bored, and scraped to exact size. Bearings shall be supported on rigid cast- 
 iron pedestal which also supports the fan housing. 
 
 Shaft. Shaft shall be made of steel forging carefully turned and after the key- 
 ways are cut, shall be accurately ground and polished. Shaft shall be tapered to 
 give ample strength where the wheel is mounted, and to reduce the size through 
 the bearing to prevent excessive bearing speed. 
 
 Wheels. Blades of blast wheel shall be of refined steel plate; flanged and 
 riveted to the side plates which shall also be made of refined steel plate in one 
 piece, carefully cut and pressed to shaft. Blades shall be securely riveted to 
 T-arms of spider. Spider shall consist of a heavy cast-iron hub, having tapered 
 steel T-arms cast integral with it and radiating from it. Hub shall be accurately 
 bored and fitted to shaft. There shall be a steel reinforcing ring securely riveted 
 to the inlets of the wheel. Wheel shall be carefully balanced.

CONE FAN 
 
 SPECIFICATIONS 
 
 General. There shall be furnished a Sturtevant Cone Fan of 
 wheel diameter inches. 
 
 The fan shall have a capacity cubic feet per minute 
 
 against a resistance of inches water gauge when operating 
 
 at approximately R. P. M., and requiring approximately 
 
 ....:... B. H. p. 
 
 Wheel. The floats of the wheel shall be securely held between 
 a back plate supported by a cast-iron cone keyed to the shaft, 
 and an annular front plate. The floats shall be curved in the 
 direction opposite to the rotation of the wheel. 
 
 Shaft. The shaft shall be made of a steel forging and after the 
 key ways are cut shall be turned and ground. 
 
 Bearings. The bearings shall be of the brush oiling type, split 
 lengthwise along the center of the shaft and supported by chairs 
 so as to be self-aligning. Bearings shall be lined with the best 
 quality babbitt, containing upwards of 85 per cent, tin, bored 
 and scraped to exact size. 
 
 Pulley. The fan shall be equipped with a pulley inch 
 
 diameter, and with face inches wide.- 
 
 CONE FAN 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 It will be noted that the Cone Fan has no housing, and is gen- 
 erally used in connection with a plenum chamber. The back- 
 wardly curved floats give very quiet operation, and the cone fan 
 is therefore very desirable where this is a factor. 
 
Cone Fan 
 
 EXPLANATION OF TABLES 
 
 The fans of this type have no casing and deliver directly into a 
 plenum space usually of considerable size. The capacities are meas- 
 ured from a pipe discharging from the room into which the fan de- 
 livers. The maintained resistance is the static pressure in the room.

 Sturtevant Turbo-Undergrate Blower. The fan wheel shall be 
 
 not less than inches diameter, and the inside diameter of 
 
 the thimble shall be inches. Blower shall have a capacity 
 
 of cubic feet per minute against a resistance 
 
 inch water gauge and shall operate at approximately 
 
 R. P. M., and require approximately B. H. P. 
 
 Thimble. The thimble shall be of cast iron and shall have the 
 end at which the air enters curved so as to offer no sharp angle 
 to the entering air. 
 
 Fan Wheel. The fan wheel shall be of the *lisc type of sheet 
 aluminum blades, riveted to a bronze hub with hard-drawn 
 copper rivets. The hub shall be accurately machined, and the 
 wheel shall be overhung on the extended turbine shaft. 
 
 Turbine. The turbine shall be of the single pressure multi- 
 velocity type, and the casing shall be provided with inspection 
 holes fitted with removable plugs. The wheel shall be one solid 
 forging with the buckets milled in the rim. Three reversing 
 buckets shall be cast in one piece with the nozzle. Individual 
 hand-operated nozzle control valves shall be provided. The 
 set shall be furnished with a floating stuffing box, and on the 
 shaft outside the stuffing box there shall be a water deflector.

Turbo -Undergrate Blower 
 
 EXPLANATION OF TABLES 
 
 These blowers are primarily intended to create a pressure in the ash 
 pit of boilers or other furnaces. 
 
 The capacities are, therefore, measured with blower discharging into 
 a closed plenum space, the maintained resistance being the static 
 pressure in that space. 
 
 For further information as to the basis of the following tables see 
 the general explanation of tables at the front of this book.

STURTEVANT PROPELLER 
 
 FAN 
 
 SPECIFICATIONS 
 
 There shall be furnished a Sturtevant 
 
 inch Propeller Fan. The total length of the fan in 
 
 the direction of the shaft shall be inches 
 
 and the total overall diameter inches. The 
 
 fan shall have a capacity of cubic feet 
 
 per minute and shall operate at approximately 
 
 R. P. M., requiring approximately 
 
 B.H.P. 
 
 The thimble shall be made of cast iron in sizes 
 up to and including 42-inch and of steel plate in 
 larger sizes. There shall be bolted to the flange 
 of the thimble three arms to support the motor 
 and the fan wheel, which latter shall be overhung 
 on the extended motor shaft. 
 
 Motor shall be built to operate on cur- 
 rent, volts, cycles, 
 
 phase. 
 
 808 
 
Sturtevant Propeller Fan 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

STURTEV ANT - BLACKM AN 
 PROPELLER FAN 
 
 SPECIFICATIONS 
 
 We recommend the use of the specifications, on 
 Sturtevant Propeller Fans given on page 808. 
 Propeller Fans of the Blackman type are built by 
 this company only when ordered or to meet speci- 
 fications. The demand for them, however, is 
 decreasing since they are less efficient, of smaller 
 volumetric capacity, and make more noise than 
 Sturtevant Propeller Fans. For these reasons we 
 strongly advise the use of the latter type. 
 
Sturtevant - Blackman Propeller Fan 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

 PROPELLER FAN 
 
 SPECIFICATIONS 
 
 See specifications on page 808. Sturtevant 
 Propeller Fans of the Davidson type are less 
 efficient and more noisy than the standard 
 Sturtevant Propeller Fan described on pages 
 805-821, and the demand for the Davidson 
 type has therefore decreased. On special 
 order or to meet specifications Sturtevant- 
 Davidson Propeller Fans will be furnished, 
 but the other type is recommended. 
 
 844 
 
S turte van t- Davidson Propeller Fan 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

STURTEVANT TRACTRIX 
 
 FAN 
 
 SPECIFICATIONS 
 
 There shall be furnished a Sturtevant No. 
 
 Tractrix Fan, the total length in the 
 
 direction of the shaft being inches, and 
 
 the total overall diameter inches. 
 
 The fan shall have a capacity of cubic 
 
 feet per minute and shall operate at approxi- 
 mately R.P.M. requiring approximately 
 
 B.H.P. 
 
 The electric motor shall be built to operate 
 
 on current, volts, cycles, 
 
 phase. 
 
Tractrix Fan 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

DISC FAN DESIGN 1 
 
 SPECIFICATIONS 
 
 There shall be furnished a Sturtevant 
 
 inch Design 1 Disc Fan, the wheel having 
 
 blades firmly fixed to radial steel 
 
 arms cast into the hub. The casing shall be 
 of No gauge sheet steel suitably sup- 
 ported by angle irons placed around both the 
 inlet and delivery sides of the casing. Re- 
 movable feet shall be bolted to the casing. 
 
 The fan shall have a capacity of cubic 
 
 feet per minute and shall operate at approx- 
 imately R. P. M., requiring approx- 
 imately B. H. P. 
 
 876 
 
Sturtevant Disc Fan Design 1 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

DISC FAN DESIGN 2 
 
 SPECIFICATIONS 
 
 There shall be furnished a Sturtevant 
 
 Design 2 Disc Fan having a capacity of 
 
 cubic feet per minute against a resistance of 
 
 inches water gauge and shall operate at 
 
 approximately R. P. M., requiring ap- 
 proximately B. H. P. 
 
 The wheel shall have 12 floats, firmly riveted to 
 the hub. To give additional strength, sizes 42-inch 
 and larger shall have each float braced with sup- 
 ports extending from a special ring on the hub to 
 a point near the outer end of the float. 
 
 The casing shall consist of steel plate of 
 
 gauge suitably supported with angle irons on both 
 inlet and outlet sides. Removable feet shall be 
 bolted to the fan casing.

Sturtevant Disc Fan Design 2 
 
 EXPLANATION OF TABLES 
 
 These fans are not usually applied in connection with piping systems 
 because they are not efficient where a large component of the press- 
 ure is static. 
 
 Capacities are therefore measured with fan discharging into a 
 plenum space, the maintained resistance being the static pressure in 
 that space.

 i. All sections contain four rows. 
 
 2. The overall height of a heater above the bottom of the base is determined by adding to the nominal height of pipes one of 
 the following constants: 
 
 For sizes Nos. 12, 15 and 18 add 8% inches. For sizes Nos. 22, 25 and 28 add 9? s inches. 
 For sizes Nos. 31 and 36 add gj-g inches. For size No. 40 add ioj^ inches. 
 
 This additional height is due to the space occupied by the bate and by the elbow at the top. 
 \

 same to tank, should the door be left undamped. 
 
 Eliminators. There shall be provided eliminator plates to remove the entrained 
 moisture from the air after it has passed through the spray chamber. These elimin- 
 ators shall be of the horizontal cut-lip type, arranged in tiers of not more than five 
 foot widths. The plates shall be not lighter than 22 gauge steel and shall be galvan- 
 ized after they have been cut and formed to shape. The plates are to be so arranged 
 that a large part of the surface will become a washing surface for the removal of dust 
 that impinges upon them. The eliminators shall consist of one group in the direction 
 of the flow of air and be so arranged that the passage way between two plates shall 
 be continuous. 
 
 Spray Device. The spray device shall consist of a horizontal header placed across the 
 bottom of the spray chamber and fitted with vertical risers so placed as to bring 
 the spray nozzles, secured to the risers, in a plane parallel to and at a distance 
 of 48" in front of the eliminators. The upper ends' of the risers shall be capped 
 with a special cap that will permit fastening to a galvanized angle iron across 
 the top of the spray chamber, thus holding the risers securely in line. There 
 shall be not less than one atomizing nozzle for each 400 cubic feet of air washed 
 per minute. The nozzles shall be constructed entirely of bronze and shall have 
 large water ways to prevent clogging of the nozzles by sediment carried in the 
 water. The nozzle openings shall be not less than 3-16" in diameter, and shall 
 discharge not more than 1^ gals, per minute with 19 pounds pressure per square inch. 
 All piping and fittings shall be heavily galvanized. For washers of 8' height and 
 under, 1" risers shall be used; for washers over 8' in height, IM" risers shall be used. 
 
 (ill 
 
In addition to the atomizing nozzles, there shall be furnished a spray pipe across the 
 top of the spray chamber adjacent to the eliminator plates. These nozzles shall be 
 of the rain-spray type, shall be placed 6" on centers and shall have capacity to wash 
 each foot of width of the eliminators with not less than five gallons of water per 
 minute. 
 
 Strainer. The straining device shall consist of a compartment extending the full 
 width of the tank and shall be fitted with fine mesh copper wire screens arranged for 
 easy removal for cleaning. There shall be two square feet of strainer area for each 
 foot in width of the tank. The top of the compartment shall be closed with hinged 
 doors to prevent dirt washed from the air falling into it. 
 
 Diffuser Plates. Across the front of the spray chamber shall be placed a series of 
 louvre like diffuser plates to eliminate eddy currents and to prevent back splash of the 
 spray washer. The washer shall be so designed that when the fan is not in operation, 
 the spray water will be entirely retained within the spray chamber when the pump is 
 running. 
 
 Pump and Motor. For recirculating the spray water, there shall be furnished a 
 
 centrifugal pump of the double suction, split casing type. The 
 
 pump to be furnished with a bronze impeller, bronze covered steel shaft and bronze 
 bushings. The bearings shall be of the ring oiling type. Heavy cast-iron base shall 
 be furnished upon which to mount the pump and motor. An oil groove shall extend 
 completely around the cast-iron base. The pump will be driven by the motor through 
 an insulated flexible coupling. 
 
 The motor shall be of horse power, capacity at R.P.M. and designed 
 
 to operate on current of the following characteristics : 
 
 Accessories. Where necessary a suitable starter will be furnished with the motor. 
 
 A 5" diameter pressure gauge, with white dial and black figures reading to thirty 
 pounds shall be furnished with the washer. 
 
 A bronze float for maintaining constant water level in the tank will be furnished with 
 the washer. 
 
 The casing shall be fitted with a water-proof marine type fixture ready to receive the 
 electric bulb to be furnished by others. 
 
 Note. Pipe connections will be fitted to the washers for connecting the pump suction 
 and discharge to the strainer compartment and to the spray headers respectively. The 
 contractor is to furnish between the washer and pump galvanized piping in accordance 
 with the washer manufacturer's drawings.

STURTEVANT AIR WASHER TYPE "H" 
 
 EXPLANATION OF 
 SPECIFICATION REQUIREMENTS 
 
 Length of Washer. For the most efficient humidifying and cooling service, an 
 air washer must be so designed that the air and water will be in intimate contact for 
 a considerable period of time. To accomplish this, in the Sturtevant Type "H" Air 
 Washer, the spray chamber is over five feet long. The nozzles are over four feet 
 from the eliminators and the total length of the washer is seven feet. 
 
 Tank. The tank of the Sturtevant Washer is constructed of No. 14 gauge metal, 
 which is heavier than the tanks of the washers manufactured by most companies. 
 Experience has proved that the tank should be constructed in an exceptionally rigid 
 manner as it is usually required to contain several thousand pounds of water and in 
 addition to support the chamber of the spray casing. 
 
 Trap. The running trap inserted in the overflow of the Sturtevant Air Washer tank 
 completely eliminates any possibility of the fan sucking odors and gases from the 
 drain pipe. 
 
 Inspection Door. The cast-iron door with glass panels fitted to the casing, is of 
 ample size to permit easy access to the spray chamber. The rigid form prevents warp- 
 ing and eliminates the cracking of the glass. The heavy hinges assure that breakage 
 will not occur from slamming of the door or from abuse. 
 
 Eliminators. The projecting lips of the horizontal lip perforated baffles or elimin- 
 ators cut the air into many streams bringing all the air into contact with the wet 
 surfaces upon which the dirt in the air is deposited. The open construction of these 
 baffle plates causes them to be continually washed clean and drained. 
 
 Spray Device. The spray device of the Sturtevant Type "H" Washer consists of 
 not less than one nozzle for every 400 cubic feet of air washed per minute. This 
 guarantees that the spray chamber is filled with a uniform dense spray and assures 
 the thorough wetting of the air. The washing of the eliminators by supplementary 
 nozzles makes certain that the surfaces will be continually wet to cause the adherance 
 of the dust particles. 
 
 Pump. The recirculating pump is of the double suction enclosed impeller type. It 
 is bronze fitted throughout to give the maximum service and wear. The split casing 
 permits the removal of bearings, shaft or impeller without disturbing the water con- 
 nection. These pumps are especially rigid and assure permanent alignment and proper 
 operation. 
 
 Lighting Fixture. The water proof marine type electric fixture insures that the 
 interior of the washer is properly lighted at all times making the inspection easy 
 and thorough.
