Abstract (en)

[origin: US2006204382A1] A radial fan comprises a casing having a side portion and a pot-like casing portion, an impeller wheel arranged therein and having radially extending blades, an electric motor arranged at the side portion, and a pressure chamber which is formed by the casing portion and the side portion. The pressure chamber with the impeller wheel space between the blades forms in cross-section a nozzle in the manner of a venturi nozzle. The ratio of the greatest blade height H/greatest diameter D of the scroll is substantially between H/D=0.08 and H/D=0.3.
