Abstract: To design a compressor system with a screw-type compressor, the housing of which has cavities for air guidance and oil separation, in an economical way for small delivery quantities, there is a disc-shaped housing with a longitudinal dimension corresponding essentially to the rotor length, and in this housing the compressed air flowing out of the compressor and mixed with oil is deflected in a radial and a peripheral direction for oil separation. The oil separator, the oil filter and the air filter are attached as separate units to the end face of this housing. The bearing plate of the drive motor is designed as a mechanical transmission space.
