What is a HVLS fan?
HVLS fans can control environments to help prevent issues like sweaty slab syndrome, help extend shelf life of products, lower your energy bill costs, and provide more comfort and productivity for your employees and patrons. Applications include everything from agriculture, manufacturing and distribution warehouses, maintenance shops, public spaces, restaurants, fitness clubs, education auditoriums, sports facilities, and more.
Where did the term HVLS come from?
The term High-volume, Low-speed fan was originally created by the inventors of the industry, MacroAir. The original concepts stems from a need to cool dairy cows. When dairy cows are hot, they produce less milk. The MacroAir HVLS fan design has since taken off and other competitors have entered the market, like Big Ass Fans. While Big Ass Fans, with a heavy presence in marketing, tends to be the market leader in sales, MacroAir is the leader in terms of quality, cost, warranty, support, and ease of install.
What should I consider when purchasing an HVLS fan?
When you are looking to make an investment in an HVLS fan you should be looking at a couple key factors:
- Warranty - How long and what are the terms? MacroAir Fans guarantees our fans for 50,000 hours (average, 16 years) even with a DIY installation. Big Ass Fans warranty is 7 years mechanical 3 years electrical.
- Gearless direct drive vs. geared - Fewer parts means less opportunity for breakdown and longer equipment life.
- Installation - Is it easy? MacroAir Fans are much lighter, coming in at a 188 lbs (including standard mounting hardware), compared to Big Ass Fan’s 233 lbs (not including mounting hardware), which will also require additional structural support in some applications.
- Cost and return on investment - Finally, compare apples to apples pricing and look at which fan is a better value. More importantly look to see which fan will cost less to operate in the long-run.

Installing the HVLS fan
When looking to install your HVLS fans, think about cost, ease of install, hardware required, who can install or manage the install, and weight.
- Extra Equipment - Be sure to ask about the mounting equipment required. MacroAir has the optional Rapid-Mount Industrial Kit to remove guy wires up to 10ft drop length. Fan models like Powerfoil 8 may require guy wires on typical applications greater than 5 feet.
- Weight - These are really big fans! Pay attention to weight in accordance with how you are
going to install and secure your fan. The Powerfoil 8 18ft. diameter weighs 233 lbs. without mounting hardware. A comparable MacroAir AirVolution-D weighs just 188 lbs. including standard mounting hardware.
Big Ass Fans Winglets vs. MacroAir No Winglets
Here’s a few things that are important to note about the very noticeable winglets featured on Big Ass Fans’ Powerfoil 8:
- Winglets don’t necessarily mean more air. In fact, the United States Deptarment of Energy (DoE) has come out with new rulings for 2020 that may make Big Ass Fans rethink the validity of using these winglets beyond pure aesthetics.
- Winglets can increase the torque of the fan which can decrease the life of the fan.
- Winglets can create disruption in the airflow and ultimately decrease the efficiency of the HVLS fan.
