5.1 Introduction. Fans and blowers provide air for ventilation and industrial process requirements. Fans. generate a pressure to move air (or gases) against a resistance caused by ducts, dampers, or other components in a fan system. The fan rotor receives energy from a rotating shaft. and transmits it to the air.
Often, the terms fan and blower are used interchangeably, and are considered synonyms of each other. Although, both are similar in terms of circulating and supplying air, technically they are quite different from each other. The main difference between a fan and a blower is based on how the air is circulated.Generally, a fan is an electrical device that moves air, whereas a blower is a mechanical device that consists of a fan, and which channels the air from the fan and directs it to a specific location or point.hough, based on the amount of pressure they need in order to produce air, both are used accordingly. Blowers can move volumes of gas at a moderate pressure while fans move large amounts of gas at a low pressure. By definition, a fan is machine that is used to create flow within a fluid, such as air.
