Beschreibung
Zusammenfassung:	The invention provides a compression device capable of reducing noised no matter what rotation speed and press conditions are. In the device having a plurality of screw compressors, the device has screw compressors which are set to n, when the number of teeth of male rotor is set to m. The phase of male rotor is shifted to specific range. The screw compressors are connected through a gearwheel, and are operated by set of motor.
