Centrifugal Fan

Centrifugal Fan a fan uses the kinetic energy of the rotating blade to enhance the pressure of the gas thereby moving them against the resistance caused by ducts. Centrifugal fans accelerate the air by changing the direction of the flow of the air. These fans throw the constant amount of air at a constant speed. In other words you can say that the velocity of the air in a system is constant irrespective of the fact that the mass flow rate is not constant. It is one of the most commonly used fan in the HVAC industry.
