Abstract:
The invention relates to a flow rectifier for an axial fan as well as to an axial fan having a flow rectifier. A flow rectifier according to the invention for an axial fan with a hub and at least one vane is characterized in that the at least one vane can be operatively connected to the hub so as to be detachable. Since the vane and the hub can be connected so as to be detachable, the flow rectifier has a modular structure.

Claim (Index 9):
An axial fan having an impeller that can be powered by an electric motor, a diffuser, a flow rectifier with a hub and at least one vane, whereby the at least one vane can be operatively connected to the hub so as to be detachable, and the hub forms a cup with a bottom, an inner circumferential wall running in the radial direction and an outer circumferential wall running in the radial direction, whereby the hub cup has an opening in the hub bottom, a support structure and at least one circumferential ring, whereby the support structure and the at least one circumferential ring are arranged downstream from the impeller, whereby the flow rectifier can be attached to the at least one circumferential ring, and whereby the support structure has a flange ring on its side facing the center axis of the impeller, whereby the flow rectifier can be operatively connected to the flange ring positively and/or non-positively, and the flow rectifier can be operatively connected to the flange ring via a latching hook, and whereby on the inside circumferential wall, the hub has a stop facing the center axis,\n wherein the stop of the hub cooperates with the flange ring of the support structure and with the latching hook in the installed state in such a way that the axial position of the flow rectifier is fixed, whereby the at least one vane has a connection element in an area facing away from the hub.
