21ft Air Ventilation Big HVLS Fans For Warehouse​

“Light weight but with great wind power” 

Our D-700D high efficiency Big HVLS fan is the perfect solution for warehouse environments. With its powerful yet quiet airflow, it effectively circulates air throughout the space, keeping the temperature consistent and creating a comfortable working environment for employees.

When installed on the roof, our fan provides sufficient airflow to cool down the entire warehouse, ensuring proper ventilation and reducing the risk of heat-related issues. Its low power consumption allows for cost-effective operation, helping businesses save on energy expenses.

Designed with the warehouse setting in mind, our high efficiency PMSM HVLS fans are constructed using lightweight aluminum alloy materials. This not only reduces the overall weight of the fan but also enhances its strength and durability, ensuring reliable performance in demanding industrial environments.

The blades of our fan are made from high strength aluminum alloy, further enhancing their robustness. Additionally, the blades are carefully powder-coated to minimize friction, resulting in smooth and efficient airflow generation.

We have also taken the initiative to re-design the motor, reducing its weight without compromising its power output. This ensures that our fan operates efficiently and effectively, providing the necessary airflow to keep the warehouse cool and well-ventilated.

Upgrade your warehouse with our D-700D high efficiency Big HVLS fan and experience the benefits of improved airflow, reduced energy consumption, and a more comfortable working environment.

 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.

 Features 

※Energy saving: The maximum power of D-700D extra large ceiling fan is 1500 watts.
※Big wind: D-700D has a maximum wind volume of 18000m³/min.
※Natural airflow: D-700D extra large ceiling fan can form wind like natural airflow.
※Lightweight fan main body: The total weight of D-700D (main body) is 47kg.
※Built-in PMSM motor: D-700D adopts no PMSM motor and gear box.
※Stepless speed regulation: Our controller is perfectly matched with the fan, and the fan speed can be adjusted steplessly.
