Why an HVLS fan?
If you are looking for a solution to help increase occupant comfort and shelf life of your products, decrease hazards in your environment due to moisture control, or decrease your energy bill, an HVLS fan might be a perfect solution.
Where was HVLS started?
Dairy farms is the short answer. MacroAir invented the HVLS (High-volume, low-speed) industry when a dairy farm was looking for a solution to cool their cattle in order to produce more milk. Since then there have been many companies entering the market with slick marketing campaigns, like Big Ass Fans. In this comparison we look at Big Ass Fans Basic 6 model vs. EnergyLogic’s MacroAir AVD3 model. You might be surprised what 3 blades vs. 6 blades actually means.
Isn’t six blades better than three?
The short answer is no. By eliminating blades we were able to reduce the weight, wear-and-tear and ultimately reduce energy costs. Having winglets like those featured on the Big Ass Fans Basic 6 can also increase torque on the fan and could decrease the life of the HVLS fan. The MacroAir AVD3 gets the job done better with less material and energy consumption, period.

Questions to ask your HVLS sales associate
Be sure to check all the boxes when you are looking to make an investment into purchasing an HVLS fan. Answering a few of these questions up front could save you big in the long run.
- How long will they last? - It depends on the brand but some companies, like Big Ass Fans, offer a different warranty depending on who installs your Basic 6. MacroAir boasts a whopping 50,000-hour runtime, no matter who installs your MacroAir AVD3.
- Does it offer a gearless drive? - This is really important because gearless motors have fewer moving parts and less chance of breaking down. No gears means no oil, no seals, no maintenance, less weight, less noise, a total of two moving parts, and the best part, less energy consumption. MacroAir AVD3 has a no-gears approach while Big Ass Fans Basic 6 has and oil-filled gearbox with several moving parts.
- Can my fan go in reverse for winter? - Be sure to ask if your fan can rotate in reverse, and how easy it is to switch. This is really important if you’re in colder climates. Running the fans in reverse will push warm air off the ceiling and push it down to the ground without creating a chilling breeze. MacroAir features on-demand reverse with its digital touchscreen controller. Big Ass Fans Basic 6 will require a manual flip on the fans themselves, which may require a ladder or lift.
- How do I Install? - Some companies, like Big Ass Fans, require you to use a factory certified installer in order to get your full warranty. This could end up costing you more than using a third party or doing it yourself. The MacroAir AVD3 comes with everything you need for an easy installation, without hidden costs. Big Ass Fans Basic 6 may not even include mounting kits in the price of the unit.
- How much can it save me on my energy bill? - While application vary depending on use and environment, EnergyLogic’s 24 ft MacroAir AVD3 operates on a lean 50 cents a day. Big Ass Fans’ 24 ft Basic 6 could end up costing you as much as $337 per year, almost twice as much!
