Centrifugal "Blower Fan" works with centrifugal fan is similar, except that the air compression process usually is the result of several working impeller (or several stages) under the effect of centrifugal force carried out. Blowers have a high-speed rotation of the rotor blades on the rotor drive air speed movement, the centrifugal force of the air in the shape of an involute casing, along involute fan outlet flow, high-speed air stream has a certain pressure. New air from entering the center housing supplement. High-speed single-stage centrifugal "Blower Fan" works: a prime mover driven by high-speed rotation of the impeller shaft, the axial air flow from the inlet into the high-speed rotation of the impeller into a radial flow is accelerated, then into the diffuser chamber, changing the direction of flow the slowdown, which would slow down the role of the high-speed rotation of the gas stream has the kinetic energy is converted to pressure energy (potential energy), so that "Blower Fan" stable outlet pressure.
