Abstract
A rotor for radial fans wherein the blades which are secured to the peripheries of the end walls surround or are surrounded by a spirally wound rod. The end portions of the rod are fastened to the end walls so as to maintain the median portion of the rod in prestressed condition. The rod enhances the resistance of the rotor to torsional stresses.
