Abstract

The radial fan has a housing (1,2) with an axial fan wheel (3) and an air inlet (4) and air exit (5) with a floor area (6) and base surface (7) and wheel for spiral movement of the air. The wheel has a cover plate and a cover disc. The pressure area (8) is in an axial direction to a base surface and wheel covers have a pipe shaped cover edge.
