Industrial ceiling and high-volume low-speed (HVLS) ceiling fans mount to a ceiling to circulate air from overhead so they don\'t take up floor space. These air circulators are commonly used to cool machinery and help keep people comfortable in manufacturing plants, warehouses, and other areas with high ceilings and a large floor space. Reversible fans run clockwise to create a windchill effect for cooling during warm months or counterclockwise to bring warm air down from the ceiling to aid heating during cold months. Nonreversible fans run in one direction for cooling. These fans are made of heavy-gauge materials suitable for daily use, have a powerful motor that drives the fan blades to move large volumes of air, and feature high-performance bearings for a long life.
