Rotary Screw compressor is a type of gas compressors that uses a rotary type positive-displacement mechanism. They are commonly used to replace piston compressors where large volumes of high pressure gas are needed, either for large industrial applications.


The gas compression process of a rotary screw is a continuous sweeping motion, so there is a very little pulsation or surging of flow as occurs with piston compressors.
