A rotary-screw compressor is a type of gas compressor, such as for example an atmosphere compressor, that runs on the rotary-type positive-displacement mechanism. 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 jackhammers and effect wrenches. For smaller rotor sizes the inherent leakage in the rotors becomes much more significant, becoming less practical than piston types for smaller volume air compressors.
The gas compression process of a rotary screw is a continuing sweeping motion, so there is quite little pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to screw air compressor become significantly quieter and produce much less vibration than piston compressors.
