In large industrial facilities like warehouses, manufacturing plants, distribution centers, etc managing the indoor air quality is quite challenging. There are various options like having HVAC systems, high-speed floor fans, and coolers, etc. But these solutions fail to provide long term cooling solutions . HVLS fans can de-stratify large volumes of air in a way that clears air in any facility enabling the HVAC system or coolers to work more efficiently. This can improve the employee’s health and comfort in an absolute environment.
Air Quality is closely related to proper air circulation, which can be achieved by installing HVLS fans, which moves large volumes of air with minimum energy. By regulating the airflow, HVLS fans not only regulate temperature but also prevent stagnant air and dust free environment. Toxic airborne chemicals are eliminated at a rapid pace because of high air volume.
Better Air Movement
HVLS fans move a large amount of air through the buildings. Better air movement leads to improved Indoor Air Quality.
Energy and Cost savings
Better air movement leads to energy savings. Though fans can circulate air, HVLS fans can mix and distribute air more efficiently and at less speed, resulting in significant energy savings.
Heating and Cooling
During winter, warm air rises up hence the temperature at the floors is low. HVLS fans push the warm air found near the ceiling downwards where it mixes with the cooler air close to the floor and then is circulated throughout the building.

In the summer, HVLS fans help by cooling the interior of the facility. HVLS fans can cause a temperature difference of up to 7 degrees, leaving facility interiors significantly cooler.
Need for Eliminating Smaller Fans
Single HVLS fan is equivalent to at least 200 smaller fans. Instead of having a large number of smaller fans which would require frequent maintenance and expensive repairs, few numbers of HVLS can be used in replacement. This in return helps to save energy and eliminate inefficient use of power from smaller fans.
Comfort
Whether cooling in the summer months or keeping the facility warmer in the winter, HVLS fans de-stratify the heat layers and mix the air to create even temperature. This helps to provide a better environment for the employees and increases their enthusiasm.
Summary
HVLS fans provide numerous benefits irrespective of the season. They use less energy than high speed floor fans.They enhance environmental control to comfort workers and protect products. Advantages of HVLS fans should be considered carefully during the design of a building.
