Roots Double Rotor Compressor

It is a rotary positive displacement compressor, in which two Roots rotors mesh with each other to intercept the gas and send it from the inlet to the outlet. There is no internal compression.

An air compressor is a device used to compress gas. The air compressor is similar in structure to the water pump. Most air compressors are of the reciprocating piston type, with rotating blades or rotating screws. Centrifugal compressors are very large applications.
