The 4-79 and 4-2 × 79 centrifugal fans can be used for indoor ventilation and air exchange in general factories and large buildings. They can be used as both input and output gases. The types of gases transported are air and other gases that are non self igniting, non exploding, non entangling, harmless to the human body, and non corrosive to steel materials. There shall be no viscous substances in the gas, and the dust and hard particles contained shall not exceed 150mg/m3. Gas temperature: not exceeding 80 ℃, gases with similar properties can also be selected.

1. Each fan casing is made in two types: clockwise rotation and counterclockwise rotation.

2. The outlet position of the fan is represented by the outlet angle of the casing. The 4-79 type fans No3A~6A are all made into one type at the factory, and the user unit installs them in the required position according to the requirements. The adjustment range of the air outlet position is 0 ° C~225 ° C, with an interval of 45 ° C; The adjustment range of the air outlet position for No7C to 8C is 0 degrees to 180 degrees, with an interval of 22.5 degrees; The positions of the single inlet and dual inlet air outlets for No10E-20E are fixed in three different sizes: 0 degrees, 90 degrees, and 180 degrees, and cannot be adjusted. If you need non-standard models such as special machine numbers and special air outlet angles, our company can design and manufacture them for you, but please specify them in detail when placing an order.
