Centrifugal fans

Centrifugal fans move air in a radial direction relative to the shaft (a change in direction of the airflow) and increase its pressure, using centrifugal force generated by the rotation of blades mounted at angles on the fan wheel. The blades of the fan wheel can be forward-curved (for high flow and relatively low pressure), backward-curved (for medium flow and high pressure) or radial (for low flow and high pressure). Centrifugal fans are widely used in domestic and industrial applications requiring higher pressures (e.g. leaf blowers and air conditioning systems).
