The used / refurbished 15-7603-1000 is a cabin pressurization unit for aircraft maintenance pressurization tests or servicing.
This unit uses a rotary blower driven by a 3 phase electric motor to provide a source of clean, low pressure air. Air enters the unit through a dry element filter located outside of the cabinet. After the air has passed through the blower, it is either directed to the aircraft or returned to the atmosphere via the air flow control valve. A pressure relief valve has been provided to protect the blower from dead head start-up and is adjusted to open at 13 PSIG.
