HV-ES Fans vs. HVLS Fans: What’s the Difference?

What is your loading dock or facility environment like? Is it comfortable? Does the air circulate? Workers who have to work in places that are uncomfortable are less productive over time and more likely to quit if they see better opportunities. It’s also vital for many businesses to protect products stored or shipped by carefully maintaining air temperature and humidity. One useful tool for this need is the fan. There are many types of fans, though. Beuschel Sales sells HV-ES fans and HVLS fans. Their names sound similar, but they do not operate the same. What’s the difference between them?


How Do Fans Work to Control the Environment?

The function of a fan is to move air around in order to affect humidity, air temperature, or air quality. How fans do this and how well they do this depends on their design and placement. 

HVLS fans, or High Velocity Low Speed fans, are a solution that affects the environment of the facility as a whole. They are installed at ceiling level and their long blades produce large, cylindrical columns of air that cool the facility similar to the way a ceiling fan does in a home. 

HVLS fans can also help lower heating costs in the winter because, when run backward, they destratify the air, pushing heat that has risen down where it can continue to make the building comfortable instead of collecting near the roof and escaping from there. This allows the HVAC system to run less and cost less money. HVLS fans can help reduce winter heating costs by up to 30 percent.

HV-ES fans, or High Velocity Energy Saving air exchange fans, are used for more targeted problems. They are installed in trailers to force hot, cold, or musty air from the inside of the trailer and replace it with a continuous stream of fresh air that is more comfortable for workers to breathe and work in. HV-ES fans are not large fans, but they’re tough and withstand impact – which is necessary in a fan used this way. They are easy to install, simple to position, and energy efficient. In fact, their 980 CFM output provides more airflow at lower amperage than all the other comparable truck fans available. 

Turbo-ES fans are used similarly, but they are more powerful than HV-ES fans. They attach to the dock by a dual articulating swing arm and produce a continuous stream of air that is able to reach all spaces in a 53-foot trailer. 

Which of the above fans would work best for your facility’s needs depends on what those are. If you are concerned about the temperature of the whole building, an HVLS fan is your solution. If you need a fan at the loading dock to keep air moving and fresh, then an HV-ES or Turbo-ES fan would work for that problem.
