The Rotary Vane Principle
Rotary vane air compressors are a type of positive displacement system, meaning that they draw air or gas into a compression chamber before reducing the size of the chamber to increase the pressure. This is what compresses the air or gas. Using this working principle as the foundation for its operation, rotary vane compressors utilise a cyclical rotor with slots containing vanes that are able to slide in and out. The rotor sits within the system slightly off-centre, which means that as it spins, the vanes are moved with centrifugal force until they touch the compression chamber. As air enters the chamber, it becomes trapped by the vanes, meaning that as the rotor continues to spin with centrifugal force, the volume of air trapped in the chamber gradually decreases. It's this decrease in volume that increases the pressure of the now-compressed air.

In addition to a very long lifespan, these compressors can deliver clean, dry and pulse free, quality air straight from the outlet – requiring less downstream equipment. Operating at low speeds (1,450 - 1,760 rpm) results in low noise, low stresses and a long service life.
