A rotary-screw compressor is a kind of gas compressor, such as an surroundings compressor, that uses a rotary-type positive-displacement system. They are commonly used to displace piston compressors where huge volumes of high-pressure atmosphere are needed, either for large commercial applications or to operate high-power surroundings tools such as jackhammers and impact wrenches. For smaller rotor sizes the inherent leakage in the rotors becomes much more significant, getting less useful than piston types for smaller volume air compressors.
The gas compression process of 
a rotary screw is a continuous scroll air compressor sweeping movement, so there is quite little pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to be considerably quieter and produce significantly less vibration than piston compressors.
