1、BF fan box overview

1.1.BF type fan box wheel adopts forward inclined multi-wing wheel and low noise external rotor motor, motor and the wheel are directly connected, fan noise is low than belt driven fan box. Fan install form divided horizontal (W) and vertical (L) is two types. Fan install form divided horizontal (W) and vertical (L) is two types. Fan install form divided horizontal (W) and vertical (L) is two types.
1.2.To adapt to different venue noise requirements, fans can all be equipped with different length silencers, and can also increase the fan noise suppression type box to make the fan noise less. 1.2.To adapt to different venue noise requirements, fans can all be equipped with different length silencers, and can also increase the fan noise suppression type box to make the fan noise less.

5、BF type fan box processing process
5.1. Wind fan wheel, machine shell is high quality galvanized plate, all molded production, using riveting, bite mouth and other means, surface clean and flat, no welding deformation phenomenon.
5.2.Fan silencing type box body adopts frame, box board assembly structure, frame adopts advanced metal cold bending unit once stretched and made (can also be used according to user needs aluminum alloy profile), box board outer layer is galvanized plate or color coated plate, surface clean and beautiful, corrosion resistant strong, inner layer is high quality PVC or galvanized silencing microporous plate, the interlayer is ultrafine glass cotton, can further reduce noise.
