The two most common types of centrifugal blowers are pressure blowers and volume blowers.
Centrifugal blower 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.
These fans increase the speed and volume of an air stream with the rotating impellers.
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 low pressure area at the center of the fan creates a vacuum that draws air into the fan.
Centrifugal blowers or fans are among the most efficient and versatile pieces of air moving equipment.
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.
Such a fan is also called a blower fan biscuit blower or squirrel cage fan because it looks like a hamster wheel.
It also adds kinetic energy to the air.
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.
