Abstract (en)
[origin: EP2196679A2] The radial fan impeller (1) has a number of circumferentially distributed blades (2) which on the inlet side (16) over their radial extent to the outlet section (6) are connected to a shroud disc (20) which has a central inlet opening (22) running into the inner inlet section (4) of the impeller. Radially shorter intermediate blades (28) are connected to the shroud disc and installed in regions between adjacent blades and from the outer circumference of the shroud disc extend only over a part of the radial extent of the shroud disc and end at a radial distance from the hub (24).
