ABSTRACT:
A compressor oil recovery device for use in removing oil from compressors typically found on condensing units used in air conditioning or refrigeration applications is disclosed. The device consists of a canister with a lid that contains a vacuum port, a suction port, a drain port, and a vacuum release port. A vacuum hose is connected at one end to the vacuum port and at the other end to an electric vacuum pump. A suction hose is connected at one end to the suction port and at the other end to the gauge manifold of a compressor. Upon activating the vacuum pump, a vacuum is created that draws the compressor oil into the canister where it is collected for disposal.
