How Big Are HVLS Fans?

An HVLS fan (high-volume, low-speed) is a ceiling fan with a tip to tip diameter greater than 7 feet (2.1 meters). The HVLS fan’s size and design allow it to move large amounts of air at a slow speed. The result is energy efficiency and comfort.

A high-quality HVLS fan gently circulates air to create a cooling effect of up to 10°F (6°C). It also works with a forced hot air system to push warm air down from the ceiling in winter, resulting in savings of up to 30 percent.

Big Ass Fans® was launched in 1999 as the HVLS Fan Co., but later changed its name to be more self-explanatory. The company has been at the forefront of HVLS technology, with patented innovations in fan blade shape, silent operation and efficient, maintenance-free motors. Big Ass Fans sells HVLS fans that range in diameter from 8 to 24 feet (2.4 to 7.3 meters).
