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.
