Dry rotary compressors

The only moving part is the rotor, which has a series of grooves along its length in which the vanes engage and slide, requiring no lubricant.
 
The rotor rotates inside a cylindrical stator. During rotation, centrifugal force pushes the vanes out of the grooves to form individual compression cells.
 
As a result of the rotation, the volume of the cells decreases and the air pressure inside them increases. High-pressure air is then directed to the outlet mechanism for use.
 
Rotary compressors have the advantage of supplying pulsation-free air at a certain pressure and therefore do not require a storage tank.
