ABSTRACT:
A radial fan has airfoil-like, backwardly curved blades placed between a support plate and a cover plate. The blades are so formed that the blade entry angle on the cover plate side is 4.degree. to 7.degree. smaller than the blade entry angle on the support plate side and the blade exit angle on the cover plate side is 3.degree. to 6.degree. smaller than the blade exit angle on the support plate side. The blade entry angle on the cover plate side is between 14.degree. and 20.degree. and the blade exit angle on the cover plate side is between 39.degree. and 45.degree.. This form is produced by twist of the blades or twist-free deformation thereof.
