Abstract

Provided is an air compressing device that can suppress degradation of oil, realize reliable operation even under humid environment, and further prevent efficiency when generating compressed air from being reduced. An oil recovery unit 17 is configured to have guided thereto compressed air that was compressed along with oil in a compressor 14, separate the oil from the compressed air, and recover the oil in an oil tank 17a. A dehumidifier 20 subjects the compressed air from which oil has been separated to dehumidification. A compressed air delivery unit 22 delivers the dehumidified compressed air to an air reservoir 23 for accumulating compressed air. A changeover valve 21 is provided on a path that communicates the dehumidifier 20 with the compressed air delivery unit 22. A communication path 35 communicates the changeover valve 21 and the suction side of the compressor 14. The changeover valve 21 is switched so that all of the dehumidified compressed air is supplied to either the compressed air delivery unit 22 or the communication path 35.
