A fan is a device that propels and moves air thanks to the rotation of the blades. These devices are used to ventilate rooms, displace gases and cool different elements.
What fans do is disperse the air. In this way, they help to refresh a room. The rotation of the blades, however, is possible thanks to the presence of a motor, generally powered by electrical energy. In a house, it is possible to use different types of fans. Floor fans are portable and stand on the surface. These kits are very popular as they do not require installation and can be easily moved around the house.
Ceiling fans, however, must be installed by a professional. As the name implies, they are fixed to the ceiling, dissipating air from the upper part of the room. By utilizing airspace, they are ideal for small venues. There are also personal fans. These small machines can be connected to the computer (PC) via USB port or charge batteries, depending on the model. An artificial respirator or mechanical ventilator, on the other hand, is a device that replaces the lung ventilation of a person suffering from respiratory failure. Thus, when a subject cannot breathe spontaneously normally, he can count on the help of a mechanical ventilator. Typically, mechanical ventilators are found in intensive care units in hospitals. In addition, mechanical ventilators may be available in the homes of individuals with home care and in ambulances dedicated to emergency transfers .
