Abstract: An axial ventilator has an external-rotor drive motor having an external rotor with a rotor shaft and an internal stator, wherein the external rotor rotates about the internal stator during operation of the external-rotor drive motor. A ventilator wheel driven by the external rotor is provided. A bearing support tube is arranged in the internal stator. A radial plain bearing is arranged in the bearing support tube and supports the rotor shaft. An axial bearing formed by a free end of the rotor shaft and a stationary counter member, against which the free end of the rotor shaft rests, are provided. The stationary counter member comprises a thrust element and an elastomeric shaped member. The thrust element is connected to the elastomeric shaped member.

Abstract: A cover for a fan (2) which can be mounted on a base (3) for cooling electric sub-assemblies or elements which are located on the base (3) characterized by a cover plate (4) which is equipped with air through-flow openings (5) as well as by fastener elements (10) for the fan which are connected to the cover plate (4) and by elements (11a, 11b) for the base (3) where the fastener elements (10, 11a, 11b) are constructed in such a manner that the cover plate (4) can be detachably attached to the base (3) in the position where it is placed at a distance from the base (3) and where the fan (2), which can be attached to the cover plate (4), is located in an intermediate position.
