A rotary-screw compressor is a kind of gas compressor, such as for example an surroundings compressor, that runs on the rotary-type positive-displacement system. They are commonly used to replace piston compressors where huge volumes of high-pressure surroundings are required, either for large industrial applications or even to operate high-power air flow tools such as 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 volume air compressors.
The gas compression procedure for a rotary screw is a continuing sweeping movement, so there is quite small pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to become considerably quieter and produce significantly less 
vibration than piston compressors.
