A rotary-screw compressor is a kind of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement system. They are commonly used to replace piston compressors where large volumes of high-pressure air flow are needed, either for large industrial applications or even to operate high-power surroundings tools such as jackhammers and effect wrenches. For smaller sized rotor sizes the inherent leakage in the rotors becomes much more significant, getting less practical than piston types for smaller sized volume air compressors.
The gas compression process of a rotary screw is a continuing sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors. This also allows screw 
compressors to become significantly quieter and produce significantly less vibration than piston compressors.
