Using "multi-stage" compression, side channel blowers generate low-pulsation blast air. Perfected impeller design with curved blades guarantees optimum efficiency. Separation Of the compression chambers on both sides of the impeller permits single-stage, twin-flow as well as two-stage, single-flow operation with only one impeller. Intake filter and pressure 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.
