OIL-FREE ROTARY VANE VACUUM PUMPS

Oil-free rotary vane vacuum pumps consist of a rotor in an eccentric position rotating inside a cylindrical body.

This rotor is equipped with grooves in which the vanes are inserted. Because of the centrifugal force, during the rotation the vanes are pushed into contact with the body, creating close spaces that increase their volume drawing air from the container to be emptied and expelling it from the “outlet duct”. Oil-free rotary vane pumps can run continuously both at atmospheric pressure and at the highest vacuum. However, they cannot be used when the aspirated air contains moisture, oil or other traces of liquid.
All versions can be used as compressors.
