Commercial and
industrial HVLS fans
Find the right industrial or commercial fan to get the most out of your facility.
What Is an HVLS Fan?
An HVLS (High-Volume, Low-Speed) fan is a large industrial ceiling fan, 7 to 24 feet in diameter, designed to move massive volumes of air at a low rotational speed. The gentle air movement these fans create mimics a natural breeze, reducing the effective temperature in a space by 8 to 15 degrees Fahrenheit in summer through the evaporative cooling effect. In winter, running the fan in slow reverse pushes warm air that has stratified near the ceiling back down to the occupied zone, reducing heating costs by up to 30%. Unlike standard industrial fans that force high-velocity air in a narrow column, HVLS fans distribute airflow evenly across the full coverage area. One Hunter HVLS fan can replace dozens of smaller spot fans while consuming a fraction of the energy.

How to Size an HVLS Fan for Your Facility
Two variables determine the right fan diameter for your space: ceiling height and square footage. Use the table below as a starting point. Obstructions (racking, overhead cranes, mezzanines) and application-specific requirements may adjust the recommendation.
| Ceiling Height | Up to 5,000 sq ft | 5,000–10,000 sq ft | 10,000–15,000 sq ft | 15,000+ sq ft |
|---|---|---|---|---|
| 10–16 ft | Up to 8 ft | 8–10 ft | 10–12 ft | 12+ ft / multiple |
| 16–24 ft | 10–12 ft | 12–16 ft | 14–20 ft | 20–24 ft |
| 24–40 ft | 12–14 ft | 16–20 ft | 20–24 ft | 24 ft + multiple |

HVLS Fans Work Year-Round
A common assumption is that HVLS fans are a summer purchase. They are not. The return on a Hunter HVLS fan spans all 12 months.
Summer cooling
Running at low speed in a counterclockwise direction, HVLS fans create a wind chill effect that makes a space feel 8 to 15 degrees cooler without lowering the actual air temperature. Facilities can reduce HVAC runtime and operating costs while maintaining worker comfort standards per ASHRAE Standard 55.
Winter destratification
Warm air rises and stratifies at the ceiling in cold weather, sometimes 10 to 20 degrees warmer at ceiling height than at the occupied zone. Running HVLS fans in slow clockwise reverse pushes that warm air back down without creating a draft. Facilities consistently report heating cost reductions of 20 to 30% after installation.

Frequently Asked Questions About HVLS Fans
What does HVLS stand for?
HVLS stands for High-Volume, Low-Speed. The name describes the core operating principle: a very large fan blade span moves an enormous volume of air per rotation while spinning slowly enough that the airflow feels like a gentle, natural breeze rather than a forced draft. The category was developed in the 1990s specifically for large industrial and commercial spaces where conventional high-speed fans could not provide adequate coverage or comfort.
How big do HVLS fans get?
Commercial HVLS fans range from 7 to 24 feet in diameter. Hunter Industrial offers models from 8 feet (XP series) through 24 feet (Titan series). Fan diameter is selected based on the square footage of the coverage area and the ceiling height of the facility.
What is the coverage area of an HVLS fan?
Coverage area scales with fan diameter and ceiling height. At the high end, a 24-foot Titan HVLS fan covers up to 22,500 square feet. Smaller models cover 7,700 to 13,000 square feet depending on size and ceiling configuration. See the sizing guide above for diameter recommendations by space size and ceiling height.
How do HVLS fans work in winter?
In winter, HVLS fans run in slow clockwise reverse at the lowest speed setting. Warm air that has stratified at the ceiling, often 10 to 20 degrees warmer than at floor level, is gently pushed back down to the occupied zone without creating a noticeable draft. Facilities consistently report heating cost reductions of 20 to 30% after installation. The same fan that cools your facility in summer pays for itself faster because it works year-round.
What is the difference between direct drive and gear drive HVLS fans?
Direct drive fans use a permanent magnet motor connected directly to the fan blade hub with no gearbox and no oil required. Gear drive fans use a gearbox to translate motor speed to blade speed, which requires oil changes, produces more noise, and introduces a potential oil contamination risk. All Hunter Industrial HVLS fans are direct drive. This means lower maintenance cost, quieter operation (under 55 dBA on the Titan), and food-safe eligibility in processing environments where oil contamination is a disqualifying factor.
How much does an HVLS fan cost?
Commercial and industrial HVLS fans are specified for permanent installation in large facilities and priced accordingly. Cost varies by fan diameter, model, mounting configuration, and control options. Operating cost is well-documented: a 24-foot HVLS fan typically runs for less than $0.50 per day in electricity. Contact us for a quote specific to your facility size, model requirements, and quantity.
What ceiling height do I need for an HVLS fan?
The minimum recommended ceiling height for HVLS fan installation is 10 feet AFF (above finished floor). Performance improves significantly in spaces with 20-foot or higher ceilings, where stratification is most pronounced and the full airflow column can develop without obstruction. As a general rule, the fan should hang at a distance below the ceiling equal to at least 25% of its diameter.
What HVLS fan certifications should I look for?
For most commercial and industrial applications, look for ETL listing to ANSI/UL 507 (the primary US safety standard), AMCA certification for independently verified airflow performance, and NFPA 13/72 compliance if your facility has an active fire suppression system. For wet locations or wash-down environments, IP66 rated drive enclosures are required. Hunter Industrial's Titan series carries all of these certifications.
How many HVLS fans do I need for my facility?
Fan quantity depends on total square footage, ceiling height, obstructions (racking, mezzanines, overhead equipment), and application requirements. A single 24-foot Titan covers up to 22,500 square feet in an open, unobstructed space. Facilities with racking or partial obstructions may need additional units. Contact us for a no-cost fan assessment and we will calculate the right quantity and placement for your specific floor plan.
Are Hunter HVLS fans suitable for outdoor or wet locations?
The DDI HVLS Fan with an IP66-rated Fan Drive Enclosure is designed for wet-location and outdoor-adjacent applications, including open-sided facilities, covered loading docks, and wash-down environments. The IP66 enclosure provides protection against water ingress from any direction. Contact us to confirm the right configuration for your specific environment.
