ABSTRACT:
A ventilator comprising a rotating plate provided on its lower surface with blades forming a centrifugal turbine surmounting the mouth of a ventilation duct or ducts in whose axis said turbine creates an ascending vortex effect. The aspiration to which the main duct or ducts are subjected is obtained by the rotation of a turbine (4a) comprising a flange (4) and a plurality of blades (10) fastened to lower surface of flange (4). The blades have a trough shape facing away from the direction of rotation of the turbine, the blades having an inner edge that makes an angle of less than 90 degrees with the flange.
