Abstract
An oil-cooled air compressor in which a control unit effects operation of the compressor unit in the condition that a specified period of time has elapsed since the last time the compressor unit was operated for a specified period of time or more at a temperature greater than a specified temperature, to thereby effect dewatering operation of the separator of the compressor only when necessary, resulting in the reduction of wasteful consumption of energy.
