What is rotary screw compressor and its benefits?

Rotary screw air compressor are simply rotary positive displacement machines, capable of high speed operation over a wide range of operating pressures and flow rates at high efficiencies. In screw air compressors there are no valves or other mechanical forces that can cause unbalance. This allows a compressor to operate at high speeds, while combining a large flow rate with small exterior dimensions. The main advantage of using rotary screw air compressor is that it can supply compresses air continuously with minimum fluctuation in delivery pressure and generates less heat than normal air compressors which causes energy efficiency.
