A rotary-screw compressor is a kind of gas compressor, such as for scroll air compressor example an surroundings compressor, that uses a rotary-type positive-displacement system. They are generally used to replace piston compressors where large volumes of high-pressure air are required, either for large industrial applications or even to operate high-power atmosphere tools such as jackhammers and influence wrenches. For smaller 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 procedure for a rotary screw is a continuing sweeping motion, so there is quite small pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to be considerably quieter and produce significantly less vibration than piston compressors.
