Abstract
A reconfigurable grille for use in association with an axial fan, and a fan assembly including the reconfigurable grille. The reconfigurable grille includes a central hub, an outer rim, and a plurality of vanes each extending from the central hub to the outer rim. The plurality of vanes are configured to switch between at least a first configuration and a second configuration, for example, by a rotation of the central hub relative to the outer rim. The grille can further include a control element to switch the vanes between different configurations.
