Abstract
Axial low noise fan, especially for vehicle ventilation, in which, before the impeller on the suction side, there are obstacles to the current at a small distance in proportion to the diameter of the impeller, characterized in that on the suction side it is superimposed, on tips of the impeller vanes, a ring concentric to its axis of rotation, located inside the fan housing and whose spacing of the fan housing corresponds approximately to the spacing between the tips of the vanes and the fan housing.
