Centrifugal fans use a rotating impeller to increase the velocity of an airstream. As the air is sucked in direction to the blades, it gains kinetic energy. The kinetic energy is then converted to a static pressure increase as the air slows before entering the discharge. 2.) Axial Fans: Axial fans move an airstream along the axis of the fan.
