Premier Filtration and Odor Removal

In modern aircraft, the air in the cabin is provided by the environmental control system (ECS) which is designed to control the cabin pressure, cabin temperature, maintain air quality and filter/dissipate any particulate matter, smoke and odors that are present in the cabin. In a typical cabin air recirculation system, the air supplied into the cabin consists of approximately 50% outside air from the engine’s compressor stage (engine ‘bleed air’) or APU which is mixed with approximately 50% of filtered, recirculated air.
