A fan with a centrifugal impeller (a fan with many blades attached on a circumference) is classified as a turbo type, a radial type, or a multi-blade type depending on the direction of the blade outlet. Centrifugal impellers are suitable when the pressure rise is large compared to the flow rate, and multi-blade types are used when ventilation is the main purpose, and multi-stage turbo types are used when compression is the main purpose. → Multi-blade fan Source : Heibonsha Encyclopedia About MyPedia Information |
