Abstract

In a radial blower, the impeller (16) is arranged between two plane-parallel discs (30, 32) which close off the impeller (16) on its axial end sides. A partition (42) divides the inner space of the impeller (16) into a first suction space (V1) and a second suction space (V2). An inflow opening (44) for fresh air opens only into the first suction space (V1). The radial blower works as a two-stage blower, the first stage working with the first suction space (V1) as a radial blower, while the second stage works with the second suction space (V2) as a transverse-flow blower. <IMAGE>
