HVLS (High Volume Low Speed) Fans move large volumes of air at very low speeds to create a powerful, yet gentle current of air. The benefits of big industrial ceiling fans go way beyond the massive amounts of gentle, comforting air. The lower speeds required by smaller motors allowed for an incredibly efficient cooling effect at a much lower cost. Most installations of HVLS fans save 30% or more on cooling costs. In many cases, an HVAC system is not even needed.
MacroAir is the originator of this building product, and they continue to improve on their design. The genius of a MacroAir fan is rooted in aerodynamics, and after extensive testing they re-engineered the design using only six wing-shaped blades. This resulted in the most efficient air movement using less energy, less motor torque, and less wear and tear on the fan. There are many advantages to using MacroAir:
Attic Fans draw hot air and moisture out of the attic space and discharge it to the exterior. This provides a more comfortable interior environment, reduced energy use, and protects the roof structure.
