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 replace piston compressors where huge volumes of high-pressure air flow are required, either for large commercial applications or even to operate high-power surroundings tools such as jackhammers and effect wrenches. For oil-free air compress smaller sized rotor sizes the inherent leakage in the rotors turns into 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.
