A rotary-screw compressor is a kind of gas compressor, such as for example an atmosphere compressor, that runs on the rotary-type positive-displacement system. They are commonly used to displace piston compressors where huge volumes of high-pressure atmosphere are required, either for large commercial applications or even to operate high-power surroundings tools such as jackhammers and influence wrenches. For smaller sized rotor sizes the inherent leakage in the rotors becomes much more significant, becoming less useful than piston types for smaller volume air compressors.
The gas compression process of a rotary screw is a continuing sweeping motion, so there is quite little pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to become considerably oil-free air compress quieter and produce significantly less vibration than piston compressors.
