| Zusammenfassung: | The fan has an impeller (2) having an outer ring (3), a drive device and a retainer (4) including a jacket ring (5) surrounding the ring (3) in a periphery direction. The ring (3) includes a bar (6) at its outer contour, where the bar (6) is designed in blade form. The bar (6) is asymmetrically arranged at an outer contour of the ring (3). The ring (5) includes an air passage bar (7) arranged radially to the impeller at its inner contour. The rings changes an air gap (8) using the bars in such a manner that a pressure difference is generated in the gap in the same direction of the blade.
