Product Description

24 Ft Big Sized Diary Farm High Volume Low Speed Industrial HVLS Cooling Fans


  • The new self-developed external rotor motor with large torque and permanent magnet synchronization replaces the traditional motor+gearbox reducer, achieving a high degree of integration and improving reliability and transmission efficiency.
  • Aluminium alloy material is adopted in many parts to realize the lightweight design.
  • The control system adopts the closed design of IP66, which is dustproof, waterproof, moisture-proof and can withstand high temperature indoor and outdoor harsh environment.
  • The system is no position vector control,anti-electromagnetic interference, anti-radiation, small size, lightweight, beautiful appearance.
  • The system function is simple, 4 buttons easy to operation( start, stop, speed up, slow down).
  • It is made of aluminium and magnesium alloy extruded and stretched, and has the advantages of high strength, good toughness, lightweight, long life and safe operation. The fan blade surface is treated with T5+ bright surface oxidation treatment, which enhances the corrosion and oxidation resistance of the fan blade and can cope with special environmental operations.
  • Energy saving tail.

​ How does it work 


24 Ft Big Sized Dairy Farm Industrial HVLS Cooling Fans High Volume Low Speed 0

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.
