DIAMETRIC VENTILATION FAN Russian patent published in 2005 - IPC

FIELD: production of rotation wheels of ventilating fans.

SUBSTANCE: the invention is dealt with the field of production of ventilating fans, in particular with production of rotation wheels of diametric ventilating fans. The diametric ventilating fan contains a body with an inlet and a force branch-pipes, a rotation wheel with bent forwards blades fixed on the lateral discs mounted on a through shaft. The diameter of the shaft inside the wheel does not exceed_{0.1D2 of diameter of the wheel and due to this the invention ensures an increase of developed pressures, productivity and efficiency of the ventilating fan.}
