HVLS Fans
Our industrial HVLS (High-Volume, Low-Speed) fans are engineered to circulate massive volumes of air across expansive floor areas. Using aviation-grade extruded aluminum blades and precision drive systems, including our flagship King Series HVLS fans and gearless Paragon Series ceiling fans, we create a gentle, continuous breeze that de-stratifies air temperatures and delivers substantial perceived thermal relief across thousands of square meters.
Key Engineering Highlights
Diameters from 2.5m (8ft) up to 7.3m (24ft) tailored to facility ceiling height
6063-T6 aviation-grade aluminum extruded blades with aerodynamic winglet tips
Four-tier mechanical safety retention systems with high-tensile steel cables
Coverage area defined strictly in square meters (m²) and square feet (ft²)
Aerodynamic & Airflow Sizing Principles
HVLS fans operate on the principle of moving deep, wide air columns down to the floor where they transform into horizontal radial airflow across high-bay warehouse facilities. When combined with evaporative units in integrated fan and evaporative cooler combination solutions, or evaluated through our proven warehouse destratification case study, this non-turbulent breeze accelerates skin sweat evaporation to create a 3°C to 5°C cooling effect on occupants without noise or draft turbulence. Facility managers can also request a facility engineering consultation to optimize blade diameters and motor specs.

Can I use an HVLS fan to improve the air quality of my facility?
Yes. HVLS fans reduce humidity and distribute odor and smoke, providing healthy, fresh air.
Can these HVLS fans be mounted outdoors?
Traditional HVLS fans can't be mounted outdoors, but the portable series can. Moveable fans are indoor or outdoor flexible; suitable for gardens, gyms, playgrounds and so on.
Can the speed of the fan be adjusted?
Yes. A DANFOSS frequency converter with a step-less regulator varies the speed.
Do I need an HVLS fan if I already have an excellent HVAC system?
HVLS fans assist the HVAC system and spread cool air to every corner, so the AC does not need to run fully for as long.
How do I know that I need an HVLS fan?
If you have a large space and want better air-conditioning performance, air quality and ventilation, you need an HVLS fan. One fan can cover an area of up to 1,800 sq. meters depending on the size of the fan.
How long is the warranty on an HVLS fan?
RTFANS HVLS fans have a warranty period of three years.
What is the expected service life of HVLS fans?
