Abstract
An axial fan for use with a wall ring plate includes a housing having an inlet region and a rotor. The rotor has an increased rotor diameter compared to a standardised rotor diameter. On the inlet side, the inlet region has a tapered section that narrows in an arched manner in a cross-sectional view from an inlet diameter to a wall ring diameter. The axial width and radial length of the tapered section are formed in a predetermined ratio.
