FIELD: power engineering.
SUBSTANCE: claimed compressor has the casing (3), oil separator (6) to separate oil from compressed air, gas duct (8) to direct said cleaned compressed air and oil duct (7) to return separated oil to said compressor. Besides it incorporates the following components. Air-cooled heat exchanger (13) for cooling of said oil and controlled rpm cooling blower (14) to force cooling air toward air-cooled heat exchanger (10). Also, said heat exchanger recovers off-heat for recovery of heat carried by oil flowing in said oil duct.
EFFECT: recovery of heat from heated oil and suppression of compressor temperature variation.
