Zusammenfassung:	A housing (17) of a fan (1) has an inflow-side end surface (2), an outflow-side end surface (16), and a wall ring (15). The wall ring 15 extends in a direction of an axis (12) from one of the end surfaces (2) to the other (16) and adjoins a fan passage. A fan wheel (10) is arranged in the fan passage. A grid (3) is arranged on the inflow-side end surface (2). The grid has a hub (8) positioned centrally in the fan passage. Primary struts (4) extend in the radial direction between the hub (8) and the edge of the fan passage. Secondary struts (6) intersect the primary struts (4).
