The rotary screw compressor is a type of gas compressor, such as an air compressor, which uses a forced displacement rotary mechanism. These compressors are widely used in industrial applications, replacing more traditional reciprocating compressors where large amounts of compressed gas are required.
With a smaller rotor size, the inherent leakage in the rotor becomes much more significant, which means that this type of mechanism is less suitable for smaller compressors than for reciprocating compressors.

The process of gas compression on the rotating vane is a continuous sweep so that there is only a slight pulse or increase in flow as occurs in a reciprocating compressor.
A screw compressor uses two very tightly interlocking screwdriver screws called a rotor to compress the gas. In dry-running screw compressors, the gears ensure that the male and female rotors remain properly aligned without contact, which will cause rapid wear.
In oil-filled rotary screw compressors, lubricating oil connects the spaces between the rotors, providing a hydraulic seal and transferring mechanical energy between the rotors so that one rotor can be fully driven by the other.
Screw compressors are commonly used to provide compressed air for larger industrial applications. They are best used in applications requiring constant air, such as food packaging equipment and automated production systems, although a sufficient number of repetitive requirements along with some storage also represent a reasonable permanent load.
