Wall fans usually have pull chains or buttons on the device to control the speed and rotation, while allowing the angle and direction of the air to be adjusted to cover a larger area. Some models also offer a remote control for greater convenience.
How do I clean a wall fan?
To clean the fan, turn it off and unplug it. Remove the protective grill and wipe the blades with a soft cloth. Don't forget to clean the grill from dust before re-installing it.
