• The 4-72 type centrifugal blowers are mainly used for general factory and large buildings indoor ventilation, or transportation of air and other non-hypergol, not explosive, not volatile, human harmless and not steel corrosive gas. And it can be used for air blast of off gas boiler in formaldehyde plant.

• The 4-72 type centrifugal fun №2.8~6A is mainly composed of impeller, machine shell, air inlet and motor etc. in addition to it, №6C and №8~20 have the transmission part.
Impellers一Composed of 10 retroverted airfoil blades, curved wheel covers and flat plates。It is made of steel (B4-72 used casting aluminum alloy)。Through dynamic and static balance correction and over speeding operation experiment, the efficiency is high, the operation is stable and reliable, and the air performance is good.
Machine shell一is made to be two different types. Of which: No. 2.8~12 shell is made as a whole, unable to be separated. №16~20 shell is made into three openings. In addition to the two halves horizontally divided, the upper part, along with the center line, is perpendicularly divided to the two halves, connected with the bolts, convenient for installation, repairing , or impeller removal.
Air inlet一Made of the overall structure, installed in one side of the fan, and the cross section, parallel to the axis, is the curve shape, to smooth the flow into the impeller, and decease the damage.
Transmission group一Consists of a spindle, a bearing box, a rolling bearing, a belt wheel or a coupling. The main shaft is made of high quality steel. The complete structure of the bearing box adopts rolling bearing grease for lubrication.

• The type of fan, air quantity, pressure, outlet angle, rotation direction, as well as the motor model, power, speed, etc., should be marked in the type selection.
•《Performance parameters of centrifugal fan》 is provided.
