Abstract
A fan with a housing which defines an axial flow channel having a cross-section, wherein the flow channel has a first axial portion on the suction side and a second axial portion adjoining in the flow direction. The flow channel has a first cross-section in the first axial portion a transitioning cross-section through the second axial portion. The cross-section is arranged concentrically in an imaginary rectangular base area, the side edges of which coincide at least in sections with a contour of the first cross-section, and wherein the flow channel has in its second axial portion an intermediate cross-section which widens in the flow direction within the base area and which, starting from the first cross-section, increases to a second cross-section at the pressure-side end of the second axial portion.
