Product Description

Commercial Ceiling Fan Blades Cooling Industrial Large Fan

Gearless direct drive HVLS Industrial Ceiling Fans specially dedicated for large scale space. The streamlined fan blade adopts aerodynamics principles and advanced process, the diameter is from 2.5-7.2 meters, with coverage 14860m3/min. Only using the efficient servo direct drive motor, can create plenty of comfortable natural wind.

Permanent magnet servo drive motor
1. IP64, small size, no lubricating oil, low energy consumption, no maintenance, can work for nearly 15 years, beautiful appearance, especially suitable for villas, churches, cafes, restaurants, etc.
2. The motor is designed with high pyrolysis technology and the operating temperature is about 38 °C.
3. internal precision Hall induction digital closed-loop control, can correctly control the switch station, step-less speed change.

Integrated control box
4. The servo drive system can make fan has a fast reaction with DSP control core and inner complex control algorithm. In addition, it has continuously variable, precise localization and a protection system with over-voltage, over currents.

 Technical parameters 

​ How does it work 

The principle behind the extra large ceiling fan is to move a very large amount of air by using large-diameter fan blades rotating at a low speed to break up the stratified air layer. The low speed of the fan makes it more efficient to convert electrical energy into useful laminar flow, rather than generating wasteful turbulence and resistance at higher speeds-which ultimately only generates unwanted heat. These large blades move more air than their smaller ceiling fans, usually 5-20 times, and have the same cooling effect. No other cooling system can be as energy-efficient as a system using HVLS industrial fans. In fact, research shows that companies can reduce or even completely eliminate the use of expensive air conditioning systems through optimized extra large ceiling fan solutions. Some extra large ceiling fan vendors provide 3D thermodynamic models of customer rooms, which proves the effectiveness of extra large ceiling fan as a cost-effective air cooling system.
