T35-11,BT35,FT35 Axial-Flow Ventilators are products to replace 30K4 products.Based on analysis and comparation with the similar products abroad,through optimized design,the structure of the impeller is confirmed.The motor is improved and the loss of air flow is reduced.Therefore,the efficiency of the fans is 89.5% higher when the noise is 3.6dB lower than Noise A standard.We strengthen the welding of blades and impeller so that the blades can avoid breaking.

This series of fans are suitable to convey non-inflammable,non-explosive,non-corrosive gas in which no obvious dust can be found.The temperature shouldn't surpass 60 deg C.The fans are widely used in factories,warehouses,offices,residential houses to ventilate or enhance heat dissipation.They can be intervally installed in a long pipeline to increase the pressure in the pipe.

BT35-11 is an Explosion-proof Axial-Flow Ventilators and it can be used to exchange the inflammable and explosive gas.FT35-11 is a Corrosion-proof Axial-Flow ventilator which is used to convey the corrosive gas.Its performance and parameters is the same as T35-11's.
