Abstract
This invention relates to a diagonal fan with a truncated cone shaped hub (4a) of the fan wheel (4) and a truncated cone shaped air housing (2). The angle of the truncated cone of the hub (4a) and of the truncated cone of the air housing (2) are relatively small, the outlet cross section (15b) of the flow channel (15) is slightly narrower than the inlet cross section (15a), and the exhaust direction (23) of the flow channel (15) retains these angles, i.e. it is not deflected by any additional deflector walls.
