Abstract: A fan for generating a gas flow for an air-conditioning system includes a housing having a pressure chamber and a suction chamber open to each other via a connecting opening. An impeller is arranged in the housing and includes an axial suction side arranged at the connecting opening and a radial pressure side arranged in the pressure chamber. An inlet and an outlet are disposed in the housing for communicating the gas flow. A fan cut-off is disposed on the housing between the pressure chamber and the outlet. At least one cover element is arranged in the inlet and axially spaced from the connecting opening to cover at least part of a flow cross-section of the inlet.
