Introduction Of Centrifugal Fan


Centrifugal fan is a kind of machinery that relies on input mechanical energy to increase gas pressure and discharge gas.

The basic composition of a centrifugal fan: a rotating impeller and a volute casing. The function of the rotating impeller is to obtain energy from the air; the function of the volute is to collect air and effectively convert the dynamic pressure of the air into static pressure.

When the centrifugal fan is energized and rotated, it drives the impeller to rotate, driving the gas to continuously flow in and out, and generate air volume and voltage. With the shape of the impeller blades, the air volume and pressure generated by the centrifugal fan are also different.

All impellers are produced in moulds and are verified by a precision dynamic balance machine at high speed. They have the advantages of small size, high efficiency, large air volume, low vibration, low noise, superior performance, and convenient installation and debugging.

SIMO Blower specializes in manufacturing centrifugal fans with high quality and affordable prices, which are loved by new and old customers.


Product Features

Forward fan: generally a blower, the impeller hub is parallel to the edge of the impeller, and the exit angle of the impeller is greater than 90 degrees.

Backward inclined fan: Generally, it is an induced draft fan. The impeller hub and the impeller are not parallel, and the exit angle of the impeller is less than 90 degrees.
