A fan is a device that drives 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 refresh a room. The rotation of the blades, however, is possible thanks to the presence of a motor, usually powered by electricity. In a house, it is possible to use different types of fans. Floor fans are portable and sit on the surface. These kits are very popular as they require no installation and can be easily moved around the house.
However, ceiling fans must be installed by a professional. As its name suggests, they are fixed to the ceiling, dissipating the 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) through the 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 pulmonary ventilation of a person suffering from respiratory failure. Thus, when a subject cannot spontaneously breathe normally, he can count on the help of a mechanical ventilator. Mechanical ventilators are typically found in hospital intensive care units. In addition, mechanical ventilators may be available in the homes of people with home care and in ambulances dedicated to emergency transport.
