airforce / hvac fans blowers

Heating, Ventilation and Air Conditioning (HVAC control systems) are used in aircrafts for pressurizing the cabin in order to maintain ambient surface-level ambient pressure and temperature inside the aircraft.

HVAC consists of centrifugal fans and blowers, and forms the core of aircraft environmental control systems that provide thermal control, air supply, and cabin pressurization to the aircraft.

Air is bled from the compressor and passed through various stages in the engine before being pressurized or depressurized, and then passed into the cabin. Heat exchangers and cold air units are used for thermal control.

Military aircrafts also have Ram Air System, which uses a small scoop on the wings as inlet for air which is then passed on to the HVAC systems in the fuselage.

Cabin pressurization is needed for keeping the passengers’ organs intact and preventing internal bleeding and other related conditions.

This category is undergoing an expansion and will soon be up with the best in the business.
