The main purpose of the T35 axial flow fan is to replace the 30K4 type. 30K4 is an analysis and comparison of the former Soviet Union products introduced in the 1950s and similar foreign products. Through model test research, the fan airfoil is determined and the cylindrical type is used. The structure of the hub and the motor have been modified to reduce the flow loss. Therefore, the fan efficiency outlet is increased to 77% based on the circular area and 89.5% based on the outlet ring area. The noise level is reduced by 3.6dB compared to the A sound level , And the strength at the root of the leaf is enhanced to avoid blade breakage.
BT35 type explosion-proof axial flow fan adopts explosion-proof measures and chooses explosion-proof motor, so it can be used as a non-corrosive place containing flammable and explosive gas, as a general-purpose explosion-proof ventilation and ventilation equipment, T35BT35 type axial fan It can be used for general ventilation in factories, warehouses, offices and residences or to enhance heat dissipation. If the casing is removed, it can be used as a free fan. It can also be installed in series in a long exhaust duct at intervals to increase the wind pressure in the duct.
The series of products are divided into 13 types according to the diameter of the impeller, and they are arranged at a time No2.8, 3.15, 3.55, 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, etc. Each model can be equipped with 5 angles such as 15 °, 20 °, 25 °, 30 ° and 35 °.
