HVLS fans, also known as High Volume Low Speed fans, are a perfect example of simple yet innovative engineering! You must understand that, despite moving slowly, HVLS fans can circulate air over a space as large as 20,000 sqft. And what’s the secret? Their bigger blades! In this blog, we will learn why bigger blades perform better and why opting for HVLS fans in the long run is a wise investment!
Why Bigger Blades Move Air More Efficiently
1) Bigger Blades Move More Air With Less Effort
The main advantage of bigger blades is their ability to circulate huge amounts of air without operating at high speed. The broad surface region of the HVLS fan’s blades displaces more air in every rotation, building a firm but gentle airflow that covers the entire space uniformly. HVLS fans rely on blade diameter & design; On the other hand, traditional fans depend on speed to generate airflow.
2) They Ensure Uniform Air Circulation
In large spaces, stagnant air usually results in uneven temperatures, hot air near the ceiling & cool air near the floor. HVLS fans resolve this issue by slowly pushing hot air downward, distributing air evenly, and moving it back upward. This continuous process doesn’t allow hot and cold air to stay in their places, providing uniform air distribution across the space. The steady airflow helps to improve comfort, reduces condensation that can cause harm to stored goods/equipment and prevents spoilage of products in warehouses.
3) They Are More Energy Efficient
One of the most important reasons behind choosing HVLS fans with bigger blades is none other than energy efficiency. As HVLS fans circulate more air at a slow pace, the motor tends to utilise less power, which means low energy costs and carbon footprint. As a matter of fact, HVLS fans are able to lower energy consumption by approximately 30% in the summer season and cut heating expenses by around 20% in winter when utilised in reverse mode.
4) They Operate Quietly & Require Less Maintenance
Despite the giant blades, HVLS fans are silent and don’t make any sound! Their aerodynamic design and slow rotation help to minimise vibration and mechanical noise. Additionally, low-speed functionality and fewer moving parts mean less wear & tear, leading to extended lifespan of the equipment and low maintenance expenses.
5) They Provide Year-Round Comfort & Productivity
In the summer months, HVLS fans stimulate evaporative cooling, making occupants feel up to 10° F cooler without even bringing a change in the actual temperature. Whereas in winter, reversing the direction of the fan simply can circulate warm air trapped below the ceiling, providing a relaxed indoor atmosphere.
In Conclusion
In simple terms, bigger blades of HVLS fans are not just about size; they are about more efficient and more competent airflow. HVLS fans always deliver uniform air distribution, promote comfort throughout the year, operate quietly and most importantly, save energy costs!
