How rotary vane pumps work
DVS vacuum pump models are oil-free, dry rotary vane pumps that guarantee emission-free, quiet operation and do not contaminate the process. A rotor with graphite blades rotates inside the pump, with centrifugal forces pressing the vanes against the inside of the housing wall and hermetically sealing the chamber for a safe, uninterrupted operating vacuum. They are used in packaging and pneumatic conveying and other processes. Advantages include quiet operation, low wear, energy-savings and small footprint.Atlas Copco Vacuum Technique; Cologne, Germanywww.atlascopco.com/vacuum
