Considered one of the most useful and necessary elements for comfort, the fan is basically a machine whose main objective is the generation of a stream of air permanent which, however, may vary its intensity or direction according to the interest of whoever handles it. Fans can be objects of personal use (for example in a house) as well as parts of larger machines that need your presence. to ensure the ventilation of its internal parts and thus prevent overheating (for example, fans that are inside the computers).

Although it is believed that there are artificial forms of ventilation (that is, created by man) since ancient times, the fan as a technological machine was created only from the Industrial Revolution in the XVIII century. Obviously, the first forms of fans driven by energy currents were very primitive and gigantic in comparison with current fans but this basically has to do with the need that many machines and complex industrial systems to have permanent ventilation that would allow a functioning appropriate of the parties.
