A rotary-screw compressor is a type of gas compressor, such as for example an air compressor, that uses a rotary-type positive-displacement mechanism. They are generally used to 
displace piston compressors where huge volumes of high-pressure atmosphere are needed, either for large industrial applications or to operate high-power surroundings tools such as for example jackhammers and influence wrenches. For smaller rotor sizes the inherent leakage in the rotors turns into much more significant, getting less useful than piston types for smaller sized volume air compressors.
The gas compression procedure for a screw air compressor Rotary screw is a continuing sweeping motion, so there is very small 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.
