MacroAir Technologies, manufacturers of HVLS commercial ceiling fans, has published a white paper that explains why 6-blade HVLS fans lower carbon footprint

MacroAir Technologies, Inc., manufacturers of HVLS (High Volume, Low Speed) commercial ceiling fans, has published its newest white paper, "Advances in HVLS Fan Technology: How Six Blades Perform Better, Lower Energy Costs." The white paper can be downloaded from the MacroAir website at:

The free white paper, "Advances in HVLS Fan Technology: How Six Blades Perform Better, Lower Energy Costs," explains how reducing the number of fan blades from 10 to six (a 40% reduction) gives HVLS fan users a number of benefits including: a 30% drop in fan weight, a 13% decrease in the amount of energy needed to run the fan, and a 10% performance boost. Six-blade HVLS fans also put less stress on a building's infrastructure and more importantly, lower the manufacturing carbon footprint.     

"HVLS fans have always been a 'green' technology," says Eddie Boyd, President of MacroAir Technologies. "When they were invented by Walter Boyd in 1998 to help cool dairy cattle, nothing like them existed. They're incredibly energy efficient and due to airflow dynamics, do a great job of helping companies lower heating and cooling costs. However, we believed we could make them even more efficient by creating a larger airfoil shape and reducing the number of fan blades. The result is a fan that not only moves more air but requires less energy to do so."

The white paper also covers the history of HVLS fan technology as well as the physics of airflow. Although the slow movement of HVLS fans is deceptive, due to their large diameter (the smallest HVLS fan is eight feet in diameter), the fans move a large column of air down and out 360 degrees. This large column of air cools spaces much more efficiently - while requiring less energy. One HVLS fan can cool down a 20,000 square foot space and replace approximately 50 small high-speed fans.
