Collins Aerospace’s air management systems are designed to meet customer requirements for efficiency, reliability, weight, performance, safety and maintainability.
The primary functions of our air management systems include cabin air conditioning and temperature control, engine bleed air, fuel tank inerting, cabin pressurization and control, ventilation, ice protection and liquid cooling.
We offer advanced air management systems that enable a safe, healthy and comfortable environment during flight. Electric and pneumatic systems are installed on a broad array of commercial and military aircraft, both fixed wing and helicopter.
Our systems are serviced at our worldwide customer support locations, including Windsor Locks, Conn.; Maastricht, Netherlands; and Malaysia.

Cabin pressure control
The higher altitude an airplane is flying in, the lower the air density while the oxygen content is decreasing. To fly comfortably and safely in several kilometers altitude, it is mandatory to maintain a certain minimum of air pressure in the cabin.
To achieve that, our systems control the outgoing air flow relative to the fresh air flow intake entering the pressurized fuselage. This is done by specific valves (Outflow Valves) and dedicated controllers (Cabin Pressure Controller). A defined air pressure is realized based on this balance to let crew and passengers travel comfortably and safely.
In addition, the aircraft has to be protected against excessive structural loads given the resulting pressure differential between inside the aircraft and ambient. Thus related Safety Valves are installed that limit the differential pressure in both directions.

Air distribution and air control
Inside the cabin or the pressurized fuselage on an airplane, air flow with defined conditions such as temperature, humidity and quality must be provided. This is to enable cooling and ventilation for passengers and crew, as well as dedicated equipment or compartments. High performance fans are used in conjunction with valves, filters and sensors, which react to the respective requirements to establish an overall control system.
Collins Aerospace offers integrated system solution to cover the entire requirements’ spectrum acting as a systems, as well as an equipment supplier.
