RADIAL OR DIAGONAL FAN WHEEL

摘要

The present invention relates to a fan wheel (1) in a version as a radial or diagonal fan, consisting of a shroud (2) with an inlet port (4), of a baseplate (6) and of a plurality of fan blades (8) arranged so as to be distributed over the circumference of the inlet port (4) and around an axis of rotation (Z). The shroud (2) and/or the baseplate (6) 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 (Z).
