Double Stage (Ring Blowers)

Side channel blowers consist of a ring-shaped housing. Side channel and the rotor opposite create a working area between intake and blow-out connections. The blade segments of the rotor suck the air and create radial pressure during turning. The centrifugal force causes the air to be pressed to the outside in the side channel. This creates a circular current between channel and blade segments. Due to the radial pressure, the air to be compressed in the chamber begins turning. The spiral swirling compresses the air several times and causes the pressure to rise. At the end of the chamber the compressed air is then pushed pulsation-free by the rotor through the blow-out connection.
