Product Features

1. There are four drive modes of fans: A, B, C and D: A drive is used for No2.8~5, and C drive is used for No6. C drive and D drive are used for No8~12,
No 16~20 adopts B type transmission;

2. Fans № 2.8A~6A are mainly composed of impeller, casing, air inlet, motor and other parts. In addition to the above structures, No6C and № 8~20 also have drive parts;

3. Impeller: It is composed of 10 backward tilting machine airfoil blades, curved wheel covers and flat rear discs, and is made of steel plate or cast aluminum alloy. After dynamic and static balance correction and overspeed operation test, it has high efficiency,
Stable and reliable operation, good air performance;

4. Casing: It is made into two different types, among which, the No2.8~12 casing is made into a whole and cannot be disassembled. The No16~20 casing is made into three open type, which is divided into two halves horizontally
The half is vertically divided into two halves along the centerline and connected with bolts, so that the impeller can be put in or taken out during installation and maintenance;

5. Air inlet: it is made into an integral structure and installed on the first side of the fan. The section parallel to the axial direction is a curve shape, which can make the air flow enter the impeller smoothly with less loss;

6. Transmission: composed of main shaft, bearing box, rolling bearing, pulley or coupling;

7. Steel pipe or cable wiring, and grounding screws are set inside and outside the motor housing;
