Each day we're asked What does Big Ass Fans do exactly? Well, we make six- to 24-foot diameter ceiling fans that use their immense size -not speed- to move massive amounts of air over large spaces. The demand has been phenomenal with Big Ass Fans installed everywhere from Airports-to-Zoos worldwide. We entered the world in 1999 as the HVLS (High Volume/Low Speed) Fan Company, a nod to our technology. And, with each fan sold, we noticed people looking skyward in disbelief and uttering, That sure is a big ass fan.  It didn't take us long to embrace the quirky name and become the Big Ass Fans Company.
