Zusammenfassung:	Flywheel of a radial blower with blades inclined to the rear and enclosed between the hub and the cover plates. The blades (5) are fitted with preferably circular holes (15) which are located in at least one line (14) close to and parallel to the outlet edge (11). In addition holes (13) may also be fitted on a line (12) close to and parallel to the inlet edge (10). The sum total of the diameters of the holes (15) amounts to about a quarter up to about one half the length of the line (14). The line (12) of holes (13) extends at a distance of about one tenth of the length to the inlet opening n10), with the sum of the diameters of the holes being about one quarter of the length of the line (12) with the number of holes being 3 to 6.
