Leading Airlines now requesting that Pall develops fresh air filtration systems to maximize Cabin Air Quality. 2000 + 5 Maintaining the Path of Continuous Improvement Industry and airlines working together for continuous improvement in passenger and crew comfort. EASA report March 2017 FAA Website Fume Events occasionally occur and contaminants can be present in the fresh air supply. The results show that the cabin/cockpit air quality is generally of a good quality. Last year, about 100,000 flights took off around the world every single day. Aviation is still one of the safest ways to travel. 6 CURRENT STATUS 7 Current Filtration Options Particulate • Dust • Microbial VOCs • Bleed air • Airport pollution • Galley/cabin • Electrical. Ozone Standard Fit on all Aircraft Carbon/HEPA Option Increasingly adopted by Leading Airlines 8 HEPA Life Performance 9 How Odor Removal Technology Improves Air Quality WILL ü Remove non persistent odors and fume from the cabin 3 to 4 times faster than a cabin without A-CAF • By calculation and trials on an aircraft; e.g. 1 minute vs. 9 minutes when new ü Reduce the number of reported incidents • Reduce lingering smells • Improve crew confidence in Air Quality ü Demonstrate the Airline is taking all available measures to improve Air Quality WILL NOT ✕ Stop fume events (it is in the recirculation line only) ✕ Will not prevent odors In conjunction with suitable procedures: 10 Assessment of Adsorbent Filter Life ! Adsorbent filters are not absolute. Unlike HEPA they do not have a ‘terminal dP’ Efficiency and life depend on boiling points of VOC’s 11 MOVING TOWARDS COMPLETE CABIN AIR FILTRATION 12 Concept & Collaboration CONCEPT / MANDATORY ELEMENTS COLLABORATION Extensive R&D in Adsorbent Materials 20 years’ Experience in Odor Removal 20 years’ Experience in CBRN Protection 70 years’ Experience in Aerospace Engineering § Filter all the air delivered to the cabin § Retrofit existing systems § Must be easily maintainable The support of Airlines and OEMs was and continues to be vital to the success of this initiative. 13 Leveraging Bespoke, Innovative Technology § the synthetic carbon matrix has a very low pressure drop and extremely high adsorbent capacity § it is dust free, extremely durable and presents low sensitivity to humidity § Incorporates treatment technology to optimise chemisorption § Several media were tested for fractional efficiency and pressure drop, analytically and visually § Oil mist in the most penetrating particle range § HEPA performance not required to achieve required performance 14 Proven Performance - 757 Cockpit Filter - Boeing 757 Cockpit Filter § Developed by Pall to improve the cockpit air quality and reduce associated disruptions § Confirmation from the operator (DHL) that the filter has made a significant difference • Improved Air quality • Reduced Disruptions • Intending to introduce this system on newly acquired aircraft § Approved with an EASA STC and released with an EASA Form 1 15 From Concept to Prototype § Assess space claim § Validate accessibility § Generate conceptual design Concept: § CFD Analysis § Prototype build § OEM input § Installation Trials § Feasibility Review Feasibility: § Performance tests § Ground tests § Risk Reduction § Selected as preferred A320 option Prototype and product: AIRLINE SUPPORT § Risk reduction § DFMEA § Opportunities for key measurements § Test fits § Ground runs § Championing with OEM § Flight trials § Timed filter returns for analysis of actual conditions PRODUCT REALIZATION 16 Finally - True Cabin Air Filtration! § Ground test for MaVE Q4 2017 § Ready to install on your A320 aircraft late 2018 Thank you!
