Clean vacuum can be obtained without any medium in the working chamber.
It can run at high speed after high-precision dynamic balancing and has no friction between rotating parts so it has a long service life.
Gas is not compressed in the pump, suitable for extracting condensable gas.
Single pump can work in a wide range and be pumped from atmospheric pressure to less than 100Pa.
The working chamber and the surface of the screw rotor can be preserved to adapt to the harsh conditions.
