Abstract
There is provided a fan guard for mounting on an electrically-operated axial-flow fan. The fan guard comprises a plurality of fasteners for extending into a plurality of respective holes on the fan and further comprises a projection projecting outwardly from the fan guard from a central support which, in use, is coincident with a central region of the air flow from the axial-flow fan. The fasteners secure the fan guard on the fan by a friction fit between the fasteners and the holes, thereby rendering installation of the fan guard on a fan, and removal of the fan guard from the fan quick and straightforward.
