摘要

The invention relates to a radial fan wheel arrangement consisting of a circular bottom plate (2) and a circular cover plate (3) with a central inflow opening (4), as well as wheel blades (6) running between the bottom plate (2) and the cover plate (3). At least one counterweight (13) is mounted on at least one of the two plates (2, 3) in the plate edge area. Pocket-shaped recesses (9) are configured at least on one side of the plate surface in the space between the wheel blades (6) in the outer edge area of the cover plate (3) and/or the bottom plate (2). At least one counterweight (13) is mounted in the area of at least one of the pocket-shaped recesses (9).
