The main purpose of the T35 axial flow fan is to replace the 30K4 type. The BT35 fan can pass through various corrosive gases and places containing flammable, explosive, and dust-free materials. T35 and BT35 axial flow fans can be used for ventilation and heat dissipation in general factories, warehouses, offices, and residences. They can also be installed in series at intervals in long exhaust pipes to increase the air pressure in the pipes. The gas passing through T35 should be non corrosive and free of significant dust, with a medium temperature of ≤ 70 ℃.
