Zusammenfassung:	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. ^ EFFECT: the invention ensures an increase of developed pressures, productivity and efficiency of the ventilating fan. ^ 3 dwg
