Abstract (en)
[origin: WO2019030006A1] The housing (17) of a fan (1) comprises an inflow-side end surface (2), an outflow-side end surface (16), and a wall ring (15) which extends in the direction of an axis (12) from one of the end surfaces (2) to the other (16) and bounds 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), said grid having a hub (8) positioned centrally in the fan passage, primary struts (4) extending in the radial direction between the hub (8) and the edge of the fan passage and secondary struts (6) which intersect the primary struts (4).
