| Zusammenfassung: | A radial fan wheel comprising vanes (2) which are inclined against the rotational direction (8) (radial impeller inclined towards the rear), the outer edge regions (14, 7) of the top and bottom disks (3,4) projecting past the effective diameter (DAs) of the vanes. The diffusion space thus established between the bottom and top disks (1,3) and the effective and outer diameter (Das, DN) of the vanes enables the kinetic energy of the fluid to be effectively converted into static pressure). The cross-section of the diffusion space is thus embodied in such a way that it expands radially outwards in a rectangular or trapezoidal manner |
