A rotary-screw compressor is a kind of gas compressor, such as an atmosphere compressor, that runs on the scroll air compressor rotary-type positive-displacement system. They are generally used to replace piston compressors where huge volumes of high-pressure air flow are required, either for large commercial applications or to operate high-power surroundings tools such as for example jackhammers and impact wrenches. For smaller sized rotor sizes the inherent leakage in the rotors turns into much more significant, becoming less practical than piston types for smaller sized volume air compressors.
The gas compression process of a rotary screw is a continuing sweeping movement, 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.
