| Purpose:
4-79 type Centrifugal fan is modified the original HDG type Centrifugal fan, both retain the advantages of the original type HDG, and made a big improvement on the original HDG type, the fan's air good performance, high efficiency, low noise. This type of fan is mainly used in factories and large buildings indoor and ventilated take a breath, both can be used as the input gas, also can be used as the output of gas.
