Abstract

The present invention relates to a fan wheel in a version as a radial or diagonal fan, of a baseplate and of a plurality of fan blades arranged so as to be distributed over the circumference of the inlet port and around an axis of rotation. The fan wheel has a shroud with an inlet port and the shroud and/or the baseplate have/has in this case a nonrotationally symmetrical geometry which in each case has a continuous and point-invariable profile, as seen in the axial or axially parallel direction.
