Radial blower i.e. HG-blower, for high-pressure cleaning device, has circumferential wall region curved from outlet wall region in S-shape, and outlet region extended in flow direction to diffuser in cross sections

摘要

The blower (9) has a housing (11) accommodating a rotor disk, and a partition wall arranged at side walls. The partition wall engages into the rotor disk, where an inner space of the partition wall is divided into suction chambers (V1, V2). A circumferential wall region (19) is curved from an outlet wall region (22) in an S-shape. A curved region (24) forms a flow conducting element for airflow returned to one of the suction chambers. An outlet region (21) is extended in an outlet flow direction to a diffuser in cross sections. The housing is made of plastic or metal.
