Claims (2)

269 780 4 EXAMPLE 1 «. Centrifugal blower comprising a non-detachable body provided with an annular cover having a central opening located on the blow side and a body mounted therein, including return lines, diffusers and interstices therebetween, and a rotor with a shaft mounted in bearing bearings; one of which is enclosed on the side of the housing, characterized in that in order to improve production technology, reduce labor and increase efficiency, the return (4) of the device, the diffusers (5) and the baffles (6) are made entirely. 2. A blower as claimed in claim 1, characterized in that, in order to reduce the axial forces acting on the stator, the central opening (3) of the cover (2) has a diameter not exceeding the outside diameter of the bearing (10) mounted on the cover side (2). 2 drawings
