What does a fan do?

Fans are used for circulating air in rooms and buildings, for cooling people, materials, or products or for exhausting a room. Fans, while they do not act as an air conditioner, it can provide a breeze effect which can help to provide a cooling breeze. It is important to remember that a fan is not designed to cool a room by itself, but in conjunction with an air conditioner can help to expedite the process.
