Abstract: An environmental control system for an aircraft having an air pump that is powered by bleed air from an engine of the aircraft. Although the air pump is powered by engine bleed air, the air pump draws ambient fresh air from outside the aircraft, compresses the fresh air to a predetermined pressure and pumps compressed fresh air into the pressurized cabin of the aircraft without ever exposing the fresh air to the compressed engine air.
