Rotary Compressor Pump Vanes

What is a rotary compressor pump vane? A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside of a cavity.

Rotary vane pump comes with advantages that because rotary vane type vacuum pump in the gas compression is isothermal, it can pump flammable and explosive gas. Furthermore, there is no exhaust valve and friction surface, it can pump gas with dust, non-condensable gas, and water mixture. With these outstanding features, it is widely used.

However, disadvantage would be the low efficiency. It is generally around 30%, better can amount to 50% only.

How does a rotary vane vacuum pump work? Vanes are allowed to slide into and out of the rotor and seal on all edges, creating vane chambers that do the pumping work.
