摘要: A radial fan wheel arrangement includes 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). Pocket-shaped recesses (9) are configured at least on one side of a plate surface in the space between the wheel blades (6) in an outer edge area of the cover plate (3) or the bottom plate (2) or both. At least one counterweight (13) is mounted on at least one of the two plates (2, 3) on a plate edge in an area of the pocket-shaped recesses (9).
