The side/side channel blower is a rotary machine for compressing and transporting air as well as other gases. It works on the principle of rotating the blade imperative (turbine) inside the fixed stator, where the air is sucked into the working "pockets" between the blades and the stator, gradually radially accelerated , compressed and such a rotating medium/air is blowed out after each turn of the engine by centrifugal force. Compression of flowing/rotating air occurs in a specially shaped compression chamber (so-called side channel - hence the name of the blower). Physical principle: kinetic/motion energy using centrifugal forces from the rotary imperative wheel is transferred to the pumped medium and creates its flow . The blower designed in this way with a side inlet can be used both for creating vacuum and overpressure air. The two dampers installed on the suction and discharge side guarantee continuous and quiet operation.
