The disclosure relates to a flow-conducting grille for arranging on the suction side of a fan, with a grille web structure which comprises radial webs spaced apart in the circumferential direction and coaxial circumferential webs spaced apart in the radial direction, wherein the radial webs of at least one quadrant of the flow-conducting grille are curved in each case over their radial extension, viewed in the circumferential direction, towards a predetermined radial plane extending from a central axis of the flow conducting grille.

Flow-conducting grille for arranging on a fan

A protective grille for a fan has a web structure which comprises radial webs spaced apart in a circumferential direction and coaxial circumferential webs spaced apart in a radial direction. The protective grille has at least a radial outer region and a central region around a central axis of the protective grille. An envelope surface spanned by the radial outer region and the central region is of convexly curved form in the radial outer region and is of flat form, parallel to a radial plane of the protective grille, in the central region.

Protective grille with improved efficiency and noise characteristics

The invention relates to a flow-conducting grille designed as a pre-conducting grille for arranging on a suction region of a fan, wherein the flow-conducting grille has a grille web structure about an axial center line, which grille web structure comprises radial webs spaced apart in the circumferential direction and coaxial circumferential webs spaced apart in the radial direction and an outer ring, wherein an inflow side of the flow-conducting grille extends flat and parallel to a radial plane of the flow-conducting grille.
