How do rotary vane vacuum pumps and compressors work?
Rotary vane technology is synonymous with a robust and functional construction. In a cylindrical housing, a rotor with several vanes is mounted eccentrically. Due to centrifugal force, these vanes slide out and form chambers between themselves and the housing.
The pumped medium is trapped inside these chambers. During further rotation, their volume is constantly reduced. Thereby, the pumped medium is compressed and transported to the outlet.
Rotary vane vacuum pumps are available in one- and two-stage versions and can be operated with different types of lubrication or as dry-running. Operation as a compressor is also possible.
