Abstract (en)
[origin: WO2014044441A1] The invention relates to an impeller (1) for a fan, in particular an axial or radial fan having a hub (2) for connecting the impeller (1) to a drive motor and having fan blades (6) which are arranged circumferentially around the hub (2) and having pockets (9) in the hub region, having balance weights (15) which can be fastened therein, aligned in the axial direction. The balance weights (15) are made of U-shaped, bent weight clips made of spring-elastic material, having at least two opposite clip legs extending parallel to each other which are connected to each other via a bend section, and comprise a clamping gap between the clip legs. One of the clip legs extends within the pockets (9) and the other clip leg extends outside of the pockets (9), such that there is a clamping seat on a pocket wall (12) extending in the clamping gap.
