The drive mechanism of the Centrifugal fans may be direct, belt, or variable drive. Which drive mechanism a centrifugal fan features determines what speed the fan moves at, and how much this speed can be varied.
It’s blade is a drum or circular plate configuration with blades, or ribs attached around its circumference with a space in the middle, this is called an impeller. It moves the air by pushing it down an exit duct in the fan casing at 90 degrees to the impeller itself as it rotates, air then rushes to equalise the lack of air pressure through the centre of the impeller, which is then pushed out of the duct and the cycle continues. This creates much greater air pressure, with greater efficiency.
Centrifugal fans are used in many industrial processes because they are able to produce large increases in air pressure. They are often used in grain drying and and greenhouse ventilation. These are also common in air pollution control as well as heating, ventilation and air conditioning (HVAC) systems.
