<p>The impeller has a carrier part (18), which extends perpendicular to a rotational axis (12). Auxiliary blades (44) are engaged to a normal plane of a rotational axis in such a manner that particles containing fluid to be conveyed are subjected with force components, which are aligned away from a carrier part. Fan blades and the auxiliary blades are curved in a rotational direction of the fan impeller in a convex shape, concave shape and S-shape. An independent claim is also included for a radial blower with a radial fan impeller.</p> |
