IMPELLERS

As a fan impeller rotates, the impeller through centrifugal force creates vacuum or low pressure at its inlet suction side. In turn, the impeller creates a positive pressure, inducing a force of air on the discharge side. Below are some of the types of impellers, each with its own specific purpose.
