A centrifugal utility fan is a type of fan that uses centrifugal force to draw air into the fan and then expel it outwards. This type of fan is typically used in industrial and commercial settings, such as factories, warehouses, and office buildings, to provide ventilation and air circulation. Centrifugal utility fans are designed to move large volumes of air at high speeds, which makes them ideal for providing cooling and ventilation in large spaces. The fan blades are typically made of metal and are arranged in a circular pattern to create the centrifugal force needed to move the air. The blades are usually connected to a motor that is used to power the fan. The motor can be powered by electricity, gas, or other sources of energy. Centrifugal utility fans are also used in HVAC systems to help regulate the temperature and air quality in a space. They are also used in many other applications, such as in agricultural and industrial settings, to provide ventilation and air circulation.
