A oil-free air compress rotary-screw compressor is a type of gas compressor, such as for example an surroundings compressor, that uses a rotary-type positive-displacement system. They are commonly used to displace piston compressors where huge volumes of high-pressure atmosphere are required, either for large industrial applications or to operate high-power air flow tools such as jackhammers and impact 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 process of a rotary screw is a continuous sweeping motion, so there is quite small pulsation or surging of flow, as occurs with piston compressors. This also allows screw compressors to become considerably quieter and produce significantly less vibration than piston compressors.
