Here's a more comprehensive guide to the high-volume, low-speed (HVLS) fans you'll always need. In this guide, you will learn about HVLS large fans that are widely used in various tall spaces.

    As energy costs increase worldwide and health standards become more important, HVLS fans are critical to reducing costs and keeping employees safe. So the question is: How can you keep your employees and customers safe and comfortable without worrying about high air conditioning bills? So, that's where this ultimate guide comes into play.

HVLS Fan History:

    Large ceiling fans that rotate at low speeds and generate a lot of airflow have their origins on farms. The founders of HVLS fans noticed that if the temperature was too high, the cows would not produce milk. In 1998, the Department of Agriculture at the University of California, Riverside presented the challenge of cooling cows to increase milk production during the hot summer months. His solution was to invent an oversized industrial fan to keep livestock cooler and more comfortable. In 1999, the world's first HVLS fan was born.

    In 2015, Jiangsu Dawang Ventilation Machinery Co., Ltd. (DAWANGFAN) was established and has been continuously innovating in the large fan industry. Dawang Ventilation currently has a huge domestic and international distribution network.

How do HVLS fans work?

    The airflow generated by the HVLS King large fan can make the human body comfortable, sweat quickly evaporates, and the body feels effectively cooled by 5-8°C.

    So what's the rationale behind the HVLS King fan? The HVLS King fan generates a large amount of airflow, which absorbs sweat moisture from the surface of the body and accelerates the body's natural evaporation for cooling effect. The air flow formed by the HVLS fan blades forms a cone from top to bottom and pushes toward the ground. As more air flow is pushed to the ground, it flows in the horizontal direction, and then pushes upward to the roof after encountering the lateral block or the horizontal airflow adjacent to the fan. , so as to strengthen air circulation in all directions, multiple angles, and no dead ends, and eliminate temperature stratification.  

    Circulating air also has a positive effect on reducing humidity, which is not possible with traditional industrial floor fans or blowers. Conversely, HVLS King fans create a lot of updraft, forcing hot air down the ceiling, keeping employees warm in winter!

HVLS big fan vs small fan

HVLS King Large Fan

Small fan

    A large HVLS fan (fan diameter from 2.5m to 8.0m) can replace multiple small fans. Since the HVLS King fans spin slower, they are also quieter than small high-speed fans at no more than 38dba. HVLS King fans can cover more area than small fans. In addition, the small high-speed fans dissipate heat quickly, resulting in greater friction between the moving air and the still air, which is not aerodynamic and cannot produce the same cooling effect as the HVLS King fan.

    The advantage of HVLS fans is that they save space on your venue. Traditional fans have a large footprint and are a major safety hazard, and employees can trip over fans or wires. The HVLS King large fan hangs from the top of the building and does not block the view.

Heating and cooling benefits of HVLS King fans

    Have you ever been somewhere, looked at the weather forecast on your phone, and suddenly felt: “It's much cooler here! ” or “This is much warmer! ”. Well, that's exactly how the HVLS King's large energy-efficient fans keep you cool or warm, and the HVLS King fans can help our bodies adjust their comfort levels.

    Air movement increases the rate at which heat is removed from our bodies due to convection and evaporation. The moving air displaces the hot air in contact with the skin surface of our body and increases the heat transfer rate, which keeps us feeling cooler. You can see the same principle in food, if you blow a hot bowl of soup, it will cool down faster than it sits.

    In winter, you can reverse the HVLS King fan and create an updraft that forces hot air down from the ceiling to the floor, greatly maintaining employee comfort.

Is the HVLS King fan quiet?

HVLS King fans are much quieter than smaller fans and HVAC systems

    HVLS King fans are much quieter than smaller fans and HVAC systems. Small fans spin faster than large fans and produce up to 80 decibels of noise! HVAC systems require multiple mechanical parts to create airflow, which is also a noise compared to HVLS king fans. If you want a quiet and comfortable workplace, then the HVLS King fan is your best choice.

Are HVLS King fans energy efficient?

    Dawang HVLS industrial large fan is a new type of ventilation and cooling equipment developed under the premise of saving energy and reducing consumption, improving the working environment and improving human comfort. The technical feature of HVLS (High-Valume, LowSpeed) is the large air volume , low speed, take Dawang's 7.3m diameter fan as an example, the maximum speed of the fan is 55 rpm, but it can generate an air volume of nearly 15000m³ Consume no more than 1.0 kWh.

    Through the low-speed operation of the King fan, it can accelerate the air circulation in the environment, effectively realize the exchange of fresh air inside and outside, and produce 1-3 three-dimensional natural wind effect, truly realize energy saving and consumption reduction, improve the working environment, improve the Human comfort.

Do HVLS King fans improve air quality?
    EPA emphasizes the importance of increased ventilation to reduce the amount of air pollutants or pollutants in workplaces and homes. Large HVLS King fans can generate a large amount of circulating air, which is quickly exchanged with outdoor fresh air through doors, windows or roof fans. While HVAC systems help with this, they typically don't exchange with outdoor air and are expensive to maintain.

    The HVLS King fan can work independently or replace the HVAC system to replace the dirty and stale indoor air with fresh outdoor air. While most buildings have exhaust systems installed, if doors and windows are left open, their effect is lost. Installing HVLS King fans can circulate the fresh air mixed in, continuously improving indoor air quality.
