The CB-11HVLS has been specifically designed to turn rough working conditions into a breeze. Install our energy efficient HVLS fan and you’ll immediately notice the difference.

The CB-11HVLS has been designed from the ground-up to deliver ultimate energy-efficient solutions. Its fan blades are constructed of high-strength, fatigue resistant aluminum alloy, powder coated to ease cleaning and ensure long life. To further extend life, each CB-HVLS fan features incredibly reliable magnet motors to drive the fan blades directly without reduction gearing. For the best cooling solution, pair up a Cool Boss HVLS fan with a Cool Boss evaporative air cooler and spread that chilled air!

Large structures, like warehouses, can get too expensive to cool effectively with just AC alone. Large shutter doors that are often open will make it more difficult to regulate temperature. That’s where Cool Boss HVLS fans come in. They’re there to make sure that you and your employees can do their jobs to the best of their abilities without heat bringing them down by effectively spreading chilled air all throughout the facility.

When people work in uncomfortable environments, there are many ways that can go south. At best, they make a little mistake which costs you time (and as we all know time is money), and at worst an employee suffers a heat related illness. Neither option is preferred. Providing ideal working conditions doesn’t just make your employees happier, which in itself is worth it. It also makes them more productive. A comfortable environment keeps their mind focused on the task at hand.

If you’ve ever ran AC for extended periods of time, you don’t need me to tell you how expensive that can get. With a Cool Boss HVLS fan in the mix, AC will be able to more effectively travel throughout the workplace in a significantly shorter amount of time, resulting in increased energy-efficiency!

The CB-11HVLS isn’t just for summer. Our top-of-the-line HVLS fans deliver energy-efficient solutions year-round! Suppose the second floor is roughly twenty degrees warmer than the first. Trying to get the first floor warmer is just going to end up costing you big, unless you decide to simply mix the air. By using an HVLS fan to push the air down, you blend the air and create a more comfortable work environment overall. It won’t make the first-floor cooler, it’ll just evenly distribute air. This process is known as Destratification, and it ends up improving energy efficiency, comfort, productivity, as well as equipment performance.
