220v MagneticHVLS Industrial Large Residential Ceiling Fans For Restaurant

Product Description

220v Permanent Magnetic Industrial Hvls Ceiling Fans For Residential And Restaurant

• This is new large HVLS energry-saving industrial fan based on PMSM (permanent magnet synchronous motor) principle developed byDawang.With 260N.m torque,the driving force is more stronger and the torque is more stable.86% motor efficiency,IE4 highefficiency.The fan diameter from 2.5M to 7.3M,14850m³/min air volume,free maintain for life,no need to change oil and seal.20-years reliable life,W.Fans series solves the problem of ventilation and cooling in large spaces with better performance,lower energy consumption and longer life.
• Adopt high performance vector and high frequency carrier technology to make the fan start smoothly and run noiseless.
• Long life devices escort: digital potentiometer, knob switch, electrolytic capacitor and other simple operation, easy to use: save energy, effort and time!
• This series fan permanent magnet synchronous motor is dynamic, highly efficient, long-life, low noise, and wide rang of speeds, especially the feature of power output of unit volume can make the fan be used to those places with strict requirements of size & weight. Thus these excellent features make our fans have a wide range of applications, such as in industrial control field, auto industry and aerospace.

 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.
