Blue Giant HVLS Fans

HVLS (High-Volume, Low-Speed) fans are large overhead fans ranging from 7 to 24 feet in diameter that move massive air volumes gently across industrial spaces such as warehouses, manufacturing plants, and distribution centers. They provide summer cooling by lowering perceived temperatures up to 10°F, winter destratification by running in reverse to push warm ceiling air back to floor level, moisture and condensation control, and reduced HVAC system load.

HVLS fans are worth it for large open spaces with high ceilings such as warehouses, factories, and distribution centers, where a single unit can cover up to 20,000 sq ft drawing only about 0.25 kW. They deliver up to 10°F perceived cooling in summer, can reduce heating costs by roughly 29% in winter through destratification, and typically last 10–20 years with an ROI in 2–3 years; they are less suitable for low-ceiling spaces under 16 feet or heavily racked areas.

Divide your facility's total floor area by the coverage area of a single fan and round up — a 24-foot fan covers roughly 20,000–30,000 sq. ft., a 16-foot fan about 10,000 sq. ft., and a 12-foot fan about 3,600–6,000 sq. ft. Add more fans for heavily racked or obstructed spaces that create airflow dead zones, and space them 1.5–3 times the fan diameter apart along the centerline of each bay.
