Centrifugal Blower Fan

It also adds kinetic energy to the air.

Centrifugal blower fan.

Centrifugal fans and blowers typically have one of eight types of wheels that draw the air into the inlet of the blower housing through the wheel and discharges it at 90 degrees out through the discharge of the housing. Centrifugal blowers or fans are among the most efficient and versatile pieces of air moving equipment. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink. The low pressure area at the center of the fan creates a vacuum that draws air into the fan.

Centrifugal fans also known as centrifugal air blowers are one of the most widely used fans because it s more cost effective than axial fans and these fans are simpler in terms of construction. In addition to material handling applications centrifugal air blowers are popular for the hvac industry and air pollution control systems. The two most common types of centrifugal blowers are pressure blowers and volume blowers. Such a fan is also called a blower fan biscuit blower or squirrel cage fan because it looks like a hamster wheel.

Equipment cooling blowers create a more concentrated stream of air than equipment cooling fans to blow away the heat generated by electronic equipment induction heaters and high wattage bulbs. The scroll housing in a centrifugal fan accelerates the air and changes the direction of the airflow twice a full 90 degree before leaving the housing.
