A high-volume, low-speed (HVLS) fan is a large fan with sizes in diameters that range between 6 and 24 feet in diameter. A single HVLS fan is capable of displacing several smaller conventional constant speed fans (sometimes called propeller, box or panel fans) and can improve the de-stratification of warm air.

Model 780 of the MacroAir fans delivers comfort while having a sleek design for spaces requiring style and silence. Or for the budget-minded, the AirVolution-D3 is the most cost effective HVLS fan on the market today.

HVLS fans are generally ceiling fans although some are pole mounted.
