Abstract

A fan has a body, a working wheel installed therein on a shaft of drive motor, with a disc and blades, and a labyrinth sealing separating the cavity of electric motor from a flow section. To simplify design, to increase convenience of maintenance and to increase area of implementation the fan additionally has a cylinder surrounding the motor, placed in the body with formation of an axial channel before the working wheel, with circular end grooves at the side of the last one. The disc of working wheel is equipped with circular axial bosses located in the grooves, and the labyrinth sealing is made as separate radial rings placed concentrically relative to the disc bosses.
