Centrifugal blower fan is a kind of H-spd fan produced by Huahao motor which demanded from customer. we have 2 types of this fan, one is AC and another is BLDC310V, both of this 2 type can reach high energy efficiency, the AC can get “A” class ,the brushless DC can reach A+++, they are so popular in Europe and other which need energy efficiency request.
The main material of this Centrifugal blower fan is plastic reinforce PP , light but strong, we had pass the drop testing easily.
We adopt the Germany technology for this Centrifugal blower fan, during the production all the part and fan are controlled strictly by QC department according to the standards,so you will see the good quality and a reasonable price from our products. And our design is opening,you can choose the speed,power,cable color,soket..etc as you want.
