Driving Device

Driving Device

  1. High-efficiency PMSM (permanent magnet direct drive) motor without gear and lubrication oil replacement.

  2. Adopt epoxy pouring sealant technology, which has over 30 times higher heat dissipation performance than the traditional varnish dipping treatment. 

  3. With imported NSK bearing, better insulation protection and maintenance-free. 

  4. Inner rotor motor adopts the embedded technology, without the risk of falling off and demagnetization. 

  5. Multi-point installation, fixing and balancing the force, effectively reducing the jitter and shake, improving safety.

Hub Wheel

With high-strength alloy steel, and Integrated Hub wheel structure design, safe and reliable.

Hub Wheel
VFD Controlling

VFD Controlling

  1. VFD inverter controller,  with stepless speed regulation; 

  2. The controller is designed with a split-type, longer control distance of up to 200M. 

  3. With safety protection module inside, over-current, over-voltage, lack of phase, etc. 

Fan Blade

  1. High strength aircraft Aluminum alloy: AA6063T6511 with fluorocarbon coating surface processing. 

  2. Patented airfoil design with special reinforce rib support system which increase the strength of fan blade and avoids the sagging of fan tail and fatigue loss of connecting components.

  3. Color can be customized

Fan Blade

Save Energy Cost Up To 30%

Cover 1000m² + with only 1.5kw!

Big industrial ceiling fans are energy efficient,cost-effective and can provide massive air movement in large industrial and commercial spaces.

Fan Blade Plug Connection

Fan Blade Plug Connection

  1.  High strength aircraft Aluminum alloy: AA7075 Sereis;
  2.  The blades are installed in the interpolation type, which increases the contact area between the blade plug and the inner wall of the blade and improves the force performance on the blade and the blade plug,  bettering its security.

Anti-Drop Device

Unique Anti-drop structure design to prevent any risk of falling off.

Anti-Drop Device


German DIN933 Industrial Bolt and DIN125A locknut with high strength 8.8 grade, the practical stress it could endure is 10 times than normal.


Standard export package--carton box.
