Weifang U-one Machinery Equipment co.,ltd specializes in designing, manufacturing and installing of ventilation equipment.
Products Description
【Structure and principle】:
The fan is mainly composed of wind blade, motor, outer frame, protective net, support frame, louver and other components.The motor drives the wind blade to generate 4 air flows. The movable shutter type can be equipped according to the user’s needs. The shutter can be opened automatically after startup and closed automatically when it stops, so as to prevent the entry of outdoor dust and foreign matters, as well as the influence of rain, snow and downwind.

【Performance characteristics 】:
1.Fan blade is made of Krupp Stainless steel, dust-free, beautiful and durable. Special blade shape design ensures large air volume, no deformation and no fracture.
2.Both Chinese famous motor and Siemens motor are available, and the voltage and frequency of the motor can be customized. The fan specially designed by famous automobile company in China can effectively solve the heat dissipation problem of motor itself. The protection grade of motor is IP 55 and the insulation grade is F.
3.The fan pulley is made of high strength aluminum magnesium alloy, which can reduce the weight, complete impeller blade and high corrosion resistance. Design of reinforcing rib pulley. Eliminate internal stress, improve its own stiffness and stability, will not be broken.
4.The fan bearing adopts special waterproof design for double row bearing, so water can not enter. High intensity, low noise, maintenance free, long service life.
5.High strength nylon 100 turn heavy hammer opening mechanism is adopted to ensure the shutter opening and closing flexibly.
6.Imported belt is adopted to ensure service life and maintenance free.
