Abstract (en)

[origin: EP1830072A2] The frame has a frame ring (1c) for receiving an axial fan (2). A pre-conductive ring (4) is upstream to the axial fan provided in a flow direction (L). The pre-conductive ring is formed as a ring, and includes ring segments distributed over a circumference. A bar (1d) holds the axial fan, where the pre-conductive ring is fastened at the bar and includes a curved deflection profile. The frame and/or the bar are formed as a plastic molded part. An independent claim is also included for an arrangement of an axial fan in a fan frame.
