An inline centrifugal fan is a type of fan that uses centrifugal force to move air or other gases. This type of fan is commonly used in industrial settings, such as factories, to move air from one area to another. The fan is composed of a rotating impeller, which is powered by an electric motor. As the impeller rotates, it creates a vacuum, which draws air in from the surrounding area. The air is then forced out of the fan at a higher velocity, creating a pressure differential between the inlet and outlet of the fan. This pressure differential is what allows the fan to move air from one area to another. Inline centrifugal fans are often used in ventilation systems, as they are able to move large volumes of air with relatively low noise levels. They are also used in cooling systems, as they can move air quickly and efficiently.
