Centrifugal fans use a rotating impeller or wheel to increase the speed and pressure of an airstream. Air is discharged at 90 degrees to the inlet airstream. The centrifugal speed increases as the airstream reaches the ends of the fan blades and is then converted to pressure.
Centrifugal fans develop much higher pressures than axial fans and are widely used for industrial processes because of their ability to handle particulate and aggressive chemistry in the air. They are categorized by their wheel designs, materials of construction and configurations. Wheels can be airfoil, radial or backwardly inclined designs and in carbon steel, stainless steel or FRP (fiber-reinforced polymer) construction. Their configuration will determine if they are cataloged as a high-pressure blower, plug fan, square fan, or industrial exhauster.
Optional wheel designs produce different pressure ranges and CFM possibilities, efficiencies vary, and generated noise levels fluctuate. Some degree of noise attenuation is typically required for an industrial centrifugal fan.
BI wheels perform to high efficiencies at relatively low tip speeds maintaining smooth and quiet operation.
Industrial applications with improved efficiency
Airfoil wheels utilize hollow blades. These wheels can operate at a slightly higher speed while consuming less horsepower.
These wheels offer a strong structural design that is perfect for heavy material handling and dirty, dusty environments.
The closed radial wheel performs to high efficiencies at relatively low tip speeds maintaining smooth and quiet operation.
