Abstract

The invention relates to an oil-injected compressor, in particular, an oil-injected mobile screw compressor with a motor-driven compressor unit, for the generation of compressed air cooperating with an oil circuit for lubrication, the oil tank of which is housed in a subsequent oil separator device for separating the oil from the compressed air. Means for oil temperature regulation are provided, comprising a cooler with a fan. The means for oil temperature regulation comprises a speed variable drive for the fan as adjuster, a regulator device for the speed of the fan matches the heat transferred to the ambient cooling air by the cooler.
