Home > Fan (implement)


 

A fan has two purposes. Firstly, to move air for human comfort or for ventilation. Secondly, to move air or gas from one location to another for industrial purposes. Fans have broad surfaces that usually revolve. Leaves or flat objects, waved to produce a more comfortable atmosphere, are the simplest kind of fan.

Applications include ornamental decorations, climate control, cooling system, refreshing air, personal wind-generation (e.g., an electric table fan), ventilation (e.g., an exhaust fan), winnowing (e.g., separating chaff of grain), removing dust (e.g., sucking as in a vacuum cleaner), cuttings, and to provide draft for a fire.
