The fan, in a form similar to that of today, is an invention of the nineteenth century. But before the discovery and the theoretical formulation of the laws that govern physical phenomena, people have realized intuitively that the air becomes cooler if the wind blows, if one shakes the air with a palm leaf with a fan, whether in closed spaces in homes, open doors and windows etc. The principle is simple: heat felt depends on temperature, but is inversely proportional to air speed, so any air movement caused by an object makes the atmosphere cooler.

It can be assumed that centuries on end in various circumstances requiring keep temperatures bearable in workshops hardware, in mines or other works underground in areas polluted in homes, they have used methods of ventilation improvised

To ensure sufficient supply of fresh air to the mine galleries in the town Johann Justus Partels Zellerfeld, in the Harz Mountains located, has developed 1711 the first fan. With it had to ensure enough oxygen even in the deepest galleries.

In the eighteenth century, the Englishman Stephen Hales, a graduate of theological studies has shown to be more interested in sciences (chemistry, botany, anatomy) and inventions (although it will become a doctorate in theology at the University of Oxford). In 1717 he was elected member of the “Royal Society” (Society for natural sciences), London, and in 1739 receives from its Copley Medal (the oldest and most prestigious award given by the Royal Society) for his research on the bladder. Studying the role of air and water in plant and animal life, Hales noted the danger (including humans) to inhale polluted air circulating or not. Starting from the idea of Partels, Stephen Hales and Martin Friewald used since 1741 to supply fresh air fans the hospital wards and boats. At the time entrapped air and bad air were considered to be numerous cases which had as effect diseasesi.As result of the research he conducted, in 1741 he made public his invention – a fan designed to freshen the athmosphere in the mines, in hospitals, in prisons, in the holds of ships and cabins. In 1747, one such fan was installed in prison The Savoy, London. Because the health effects inmates were beneficial use was widespread in prisons fans, and in hospices, silos, etc.

In 1882, the American Schuyler Wheeler has developed the first fan with two wings. His contemporary, the German-American engineer Philip Diehl took Wheeler’s idea, fan blades mounted on a sewing machine motor and mechanism designed to be mounted on the ceiling of a room. In 1887, Diehl and obtained in the United States, the patent for the ceiling fan.

Today there is a great diversity functional and structural of these devices, to meet the needs practical – fans screw (propeller), which causes air in a move parallel to the motor shaft, radial fans, axial fans, mono and double extractor fans, tunnel fans or fans for powder particles material transport, fans for air cleaning dust, exhaust gas fans, ventilation fans warehouses, silos, office space etc.
