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.

In addition to material handling applications centrifugal air blowers are popular for the hvac industry and air pollution control systems. The low pressure area at the center of the fan creates a vacuum that draws air into the fan. These fans increase the speed and volume of an air stream with the rotating impellers. It also adds kinetic energy to the air.

Direct drive fans have fewer moving parts than belt drive fans for less maintenance. How a centrifugal fan works the rotating fan blade creates a low pressure area at the center of the blade and a high pressure area at the edges of the blade. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink. The two most common types of centrifugal blowers are pressure blowers and volume blowers.

Centrifugal blowers or fans are among the most efficient and versatile pieces of air moving equipment. 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.
