The air outlet has a cylindrical inflow connection (1) and a cylindrical outflow chamber (2). Star-shaped swirl chambers (4) are arranged in the lower portion of the outflow chamber (2), are conical in shape and have a lateral inflow opening (6). The cross-section of the outlet openings (8), arranged radially to the air outlet, of the swirl chambers (4) is smaller than the envelope surface of the cylindrical portion of the outflow chamber in the region of the swirl chambers (4). Mutually separate individual streams with a high exit momentum are produced in this manner (Fig. 3). <IMAGE>
