Rotary vane vacuum pumps

Rotary vane vacuum pumps

Rotary vane vacuum pumps pump or “evacuate”  air by spinning a rotor which has slots in it containing the vanes.  The rotor is offset of center to the cylinder wall. These vanes, due to centrifugal force are sealed against the cylinder wall; thus causing the differential pressure and pumping action.

These type of pumps have the ability to achieve a very deep vacuum, but their major drawback is that they will not tolerate any particulate inhalants and don’t care much for most liquid inhalants.
