Every desk fan has it. What's the purpose of the white cap attached to the front fan grille?
The white cap on the front grille of desk fans serves primarily a decorative purpose, providing a center for the radial wires to converge. While it could be replaced by a simple ring of wire, the cap enhances the aesthetic appeal of the fan. Some models, particularly those with expanded metal grills, may omit this feature, indicating that its presence is not functionally necessary. The design choice varies among different fan models, such as the Tesco DF98-9 desk fan.
