  • Impeller, in particular for an axial fan
    Patent number: 7442010
    Abstract: An impeller for an axial fan of the type adapted to be pressed onto a rotating rotor comprising a number of blades. The blades protrude radially outward from a substantially tubular hub, which carries the blades and is adapted to be pressed onto the rotating rotor. A substantially cylindrical blank is arranged inside the hub where the blank forms alternately arranged first and second portions. The first portions have a greater inside diameter than the inside diameter of the second portions.
