Abstract
Provided is an air compressor which exhibits improved reliability by resolving problems relating to drainage discharge defects, and exhibits improved energy efficiency. The air compressor comprises: a compressor body which compresses air; a compressed air flow path through which the compressed air from the compressor body flows; a heat exchanger which is provided to the compressor flow path so as to cool the compressed air from the compressor body; and a drainage pipe (62) which branches from the compressed air flow path so as to connect to the exterior, and through which drainage condensed from the compressed air cooled in the heat exchanger flows. A strainer (65) which removes foreign matter contaminating the drainage is provided to the drainage pipe (62). An on-off valve (66) at the downstream side of the strainer (65), and a pressure sensor (41) at the upstream side thereof, said sensor detecting pressure inside the drainage pipe (62), are each provided so as to resolve drainage discharge defects.
