Using “multi-stage” compression, side channel vacuum pumps generate low-pulsation suction air. Perfected impeller design with curved blades guarantees Optimum efficiency. Vacuum filter and vacuum safety valve can be integrated as an optional extra in the patented design of the sound absorbers. The sound absorbers can be varied in length, affording flexible adjustment to available installation space.
The frequency inverter integrated in the VARIAIR UNIT significantly enhances the performance data of side channel vacuum pumps. It matches the vacuum generators exactly to customer requirements.
