HVLS stands for high-volume, low-speed fan. These HVLS fans are bigger than 7 feet in diameter and are used to move large amounts of air to help condition big areas such as warehouses, barns, auto dealerships, auditoriums, restaurants, air plane hangars, fitness centers, and other large public gathering places.
If you are looking for more comfort, an HVLS fan can be a great asset. Not only will it help keep you cool but it cuts down on your energy bill up to 35%. In the winter, EnergyLogic’s MacroAir HVLS fans can spin in reverse, pushing the warm air off the ceilings and back down to the floor where your heat belongs.
Some companies like Big Ass Fan feature wings on their blades. Recently the department of energy has issued new compliance requirements for 2020 that significantly impact the HVLS fan industry - in a good way for consumers. The DoE has found that winglets and other wing attachments do not significantly benefit blade efficiency. In fact, other NASA-inspired design elements provide EnergyLogic’s MacroAir airfoil blades with highly efficient performance, while maintaining a simple elegant design.
When choosing a product for your space you will want to consider ease of use and technology available to help monitor your fans energy consumption. Some fans feature a geared motor that has more components at risk of breaking down. Geared motors can also produce more noise and tend to put more pressure on the structure, due to weight. Consider an EnergyLogic MacroAir gearless motor fan.

So who offers the best warranty in the industry? This is a no-brainer. MacroAir carries a full warranty with 50,000 hours of run time, or 16 years based on average run hours per year!
EnergyLogic’s MacroAir Fans are much lighter, weighing 239 lbs (including standard mounting hardware), compared to Big Ass Fan’s 347 lbs (not including mounting hardware), which will also require additional structural support in some applications.
