A rotary-screw compressor is a type of gas compressor, such as for example an air flow compressor, that uses a rotary-type positive-displacement system. They are generally used to displace piston compressors where large volumes of high-pressure air flow are needed, either for large industrial applications or to operate high-power air tools such as for example jackhammers and impact wrenches. For smaller sized rotor sizes the inherent leakage in the rotors becomes much more significant, getting less practical than piston types for smaller volume air compressors.
The gas compression process of a rotary screw is a continuous sweeping movement, so there is very small pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to become significantly quieter and produce much less vibration than piston compressors.
