RADIAL FAN

In a radial blower with two blower wheels (2, 3) fastened axially in tandem on one shaft end each of the interposed drive motor (b 1) with one blower blade circle (21, 31 respectively) held at a radial distance from the hub (26, 36) on the blower shaft side, the operating noise is to be reduced by s...

description	In a radial blower with two blower wheels (2, 3) fastened axially in tandem on one shaft end each of the interposed drive motor (b 1) with one blower blade circle (21, 31 respectively) held at a radial distance from the hub (26, 36) on the blower shaft side, the operating noise is to be reduced by simple arrangement while maintaining a high output yield; to this end it is proposed to connect the blower blade ring (21 and 31 respectively) of each blower wheel (2, 3) via spokes (22 to 25, and 32 to 35 respectively) leaving free tangential spaces and to arrange the spokes (22 to 25) of the one blower wheel (2) relative to the spokes (32 to 35) of the other blower wheel, as seen in the axial direction (blower shaft 4) in the gaps (circumferential angle of rotation alpha ) relative to each other in the circumferential direction.
