A crowded public areaHVLS fans are so versatile that they can be used in a number of places – large hangars, warehouses, or manufacturing centers. One area where these fans particularly excel is in crowded areas where huge numbers of people tend to move in and out.

To understand why HVLS fans do so well in crowded areas, we can look at a few of their key features and some real-world examples of how they’ve been used in places with a lot of people.

Large coverage areas

Because HVLS fans have such large blades, the columns of air that they create are much larger than air streams created by small box or pedestal fans. The largest fans can cover an area of over 20,000 square feet.

This is important because most places that get crowded are also large spaces – think of an airport, train station, or big lobby. These locations need a solution that can disperse air everywhere, not just in certain parts of the space.

Quiet operation

Besides their massive columns of air, another thing HVLS fans are known for is running at a whisper-quiet sound level. This is critical because most crowded areas involve people communicating or listening to information relayed over a speaker. Imagine being in an airport and trying to hear an announcement about your flight while loud fans are buzzing all around you.

Even the largest of HVLS fans are quiet enough to prevent a situation like this. Most fans operate at around 50 dBA— about the same level of noise as your home refrigerator. There’s no need to worry about noise from HVLS fans preventing people from hearing the information they need.


HVLS fans come in many different sizes and styles. Some spaces might be fine with a 16-foot fan, while others might be large enough to require a 24-foot model. No two spaces are the same – many of them have cavernous ceilings, while others are vaulted in a dome-shape. Still others may have steeples or angular ceilings. Whatever type of large space you need to improve airflow in, there’s a fan model that will help keep it cool.

Cost effective

Large spaces require more money to run: there is more furniture, larger HVAC systems, more employees needed to staff the area, and so on. If your facility is already spending a lot to maintain a large area, you probably don’t have the budget for a new cooling solution that could significantly increase your monthly operating costs.

Fortunately, HVLS fans are not this type of solution. The best HVLS fans can operate on a dollar a day, and because they work in conjunction with your HVAC system, installing an HVLS fan actually saves you money on your operating costs in the long term.

Examples of large spaces that use HVLS fans

  • Western Railway’s long-distance train terminal in Mumbai, India. The company considered using an air conditioning system or smaller fans, but found that HVLS fans were preferable because the fans could improve airflow and temperatures in an open-air setting like a train station.
  • Valencia Airport. About 5 million travelers per year pass through this airport in Manises, Spain. After installing 24-foot HVLS fans, the airport was able to efficiently cool the space and run its HVAC system at a lower level.
  • Riverside Rancheros Equestrian Center. This equestrian center in southern California regularly hosts calf roping, barrel racing and other rodeo-style events attended by 350 people or more. When they started using HVLS fans, Riverside Rancheros created a comfortable environment for guests and saved thousands per month on energy costs.

The Bottom Line

HVLS fans can help you get a better handle on cooling and heating in your crowded areas. Be sure you pick a fan with the size and capacity you need and you can minimize the cost of keeping your space comfortable and quiet for its occupants.
