Product Description

4.3m 0.7kw Gearless PMSM Big HVLS Fans For Gyms

“Light weight but with great wind power” 

Our Gearless PMSM Big HVLS Fan can quietly delivers strong airflow to cool large areas with low power consumption. It is very suitable for places such as industrial workshops, warehouses or other public places.
In order to reduce weight and increase strength, a high-efficiency PMSM HVLS fan was designed through 3D computer modeling, and the fan body was made of aluminum alloy material.

The motor has also been redesigned to reduce weight, allowing it to deliver more power efficiently.

 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 is as energy efficient as a system with HVLS industrial fans. In fact, research shows that businesses can reduce or eliminate the use of expensive air conditioning with solutions optimized for oversized ceiling fans. Some oversized ceiling fan suppliers provide his 3D thermodynamic model of a customer's room, proving the effectiveness of oversized ceiling fans as a cost-effective air cooling system.
