T4-72 centrifugal fanDetailed product description：

T4-72 centrifugal fan No.3-6 has air outlet positions ranging from 0 ° to 225 °, with intervals of 45 °, and is driven by A-type transmission; The positions of air outlets No.7 to No.20 are 0 °, 90 °, and 180 °, with N07 to No.12 being driven by C or E type, and No.16 and No.20 being driven by B type.
T4-72 centrifugal fan No.3-6 is mainly composed of impeller, casing, air inlet and other parts matched with a direct connected motor; In addition to the above-mentioned parts, No.7-20 also has transmission parts, etc.
1) The impeller consists of 10 backward inclined circular thin plate blades, a curved front plate, and a flat rear plate. All are made of steel plates and have undergone dynamic and static balance calibration
Positive, with good air performance, high efficiency, and smooth operation.
2) The casing is made into two different types. The No.3-12 casing, as a whole, cannot be disassembled. The casings of No.16 and No.20 are made in three parts, with the upper half divided vertically along the centerline in addition to being split into two halves along the horizontal plane, and connected by bolts.
3) The air inlet is made as a whole and installed on the side of the fan. The cross-section parallel to the axial direction is curved, which allows gas to enter the impeller smoothly with minimal loss.
4) The transmission part consists of a main shaft, a bearing box, rolling bearings, and pulleys.
