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