Product context
About Virtue Series
Virtue Series is designed for large factories, warehouses and high-heat industrial spaces. Its controlled air movement helps equalize temperatures and reduce stagnant air in large occupied spaces.
9,000 airflowFresh-air evaporative coolingIndustrial spaces
Operating principle
How it works
Spread air across the floor
Air moves outward from the fan and mixes warmer and cooler layers in the space.
Support comfort circulation
Air movement can improve perceived comfort, but the fan does not provide outdoor air or refrigeration.
Built for industrial use
Engineering features
Broad air movement
Large-diameter blades move room air across occupied zones and help mix temperature layers.
Facility-led layout
Ceiling height, structure, racks, lights and sprinklers affect the final fan position.
Mechanical safety review
Mounting, fasteners and secondary retention must follow the model installation instructions.
Routine service access
Inspect blades, fasteners, controls and drive components according to the model manual.

Before specifying
Operating notes
Cooling performance depends on entering air temperature, relative humidity and ventilation. The system performs best where cooled fresh air can move continuously through the space.
Service routine
Maintenance checklist
Before serviceIsolate electrical power and follow the model manual before inspection.
During routine checksInspect blades or impellers, guards, fasteners, safety retainers and controls according to the model manual.

Airflow and Installation Details
Review the airflow pattern, control system, installation conditions and operating range for this fan.
Model and drive configuration
Virtue Series is represented by RTF-SF-5EEX in the 2026 export configuration. The source specifies NORD S1 and 5 PCS blades. The technical table lists the supplied model values, including diameter, airflow, power, voltage, current, speed, noise and weight.
Application range and installation
The source labels maximum application range in cubic meters (m³). This is a volume entry, not a floor-area rating in square meters. Select fan quantity and placement using mounting height, building dimensions, obstructions and the occupied zones. These fans circulate room air; outdoor-air ventilation and process extraction require a separate design.
Performance and service
Review the selected model's operating conditions and noise measurement method before quotation. Have a qualified installer check structural support, blade clearance, safety retainers and electrical supply. Isolate power before inspection and follow the supplied motor and controller manuals for maintenance.

HVLS Fan FAQs
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?
10 years or more, depending on installation and use.
What fan sizes are available?
Diameter from 2.8 m to 7.3 m. Industrial HVLS fans: 3.7–7.3 m; commercial HVLS fans: 2.8–4.0 m; PMSM fans: 2.8–7.3 m. Applicable area 400–1,800 sq. meters.
