20 Foot HVLS Ceiling Fan | 6 Blades | 10,700 Square Foot Coverage | 208-240V or 380-480V

Product Overview

This 20-foot HVLS ceiling fan moves 406,119 CFM through six aluminum blades rotating at up to 65 RPM. The fan is powered by a 1.5 HP (1100 watt) PMSM motor and operates on either 208-240V or 380-480V input, available in single-phase or three-phase configurations. Total fan weight is 297 lbs.

The unit ships with a 39-inch downrod and includes a wall-mounted VFD controller for variable speed adjustment. At full operation, sound output measures 38 dB. The fan body carries an IP55 rating, and the included controller carries an IP66 rating.

Where This Product Fits Best

A 20-foot diameter fan of this output class fits large open spaces where air needs to move across wide floor areas from a single mounting point. The 10,700 square foot coverage specification reflects the effective air movement zone under typical ceiling heights and unobstructed conditions.

The dual voltage range accommodates both standard commercial electrical systems (208-240V) and industrial three-phase services (380-480V). Facilities with either single-phase or three-phase power available can use this fan without transformer requirements within those voltage bands.

Performance and Functional Considerations

The 406,119 CFM output at 65 RPM represents maximum airflow at full speed. The variable speed capability through the included VFD allows operators to reduce blade speed for lower air movement when conditions require it. Sound level at 38 dB remains low enough for environments where noise is a consideration during occupied hours.

The PMSM motor design supports the variable speed operation required for HVLS applications where airflow needs change seasonally or throughout the day. The 50/60 Hz frequency compatibility allows installation without concern for local electrical frequency standards.

Installation and Long-Term Use

The 297 lb total weight requires structural mounting capable of supporting the fan plus dynamic load during operation. The included 39-inch downrod sets the blade plane below the mounting surface; facilities with higher ceilings or specific clearance requirements should verify whether this downrod length positions the blades appropriately for the space.

The IP55 rating on the fan body allows installation in environments where dust and low-pressure water exposure may occur. The IP66-rated controller tolerates direct water jets and complete dust ingress protection, supporting placement in washdown areas or locations with periodic cleaning operations.

Aluminum blade construction resists corrosion in humid or damp environments better than steel alternatives. The six-blade configuration distributes load across the hub and provides consistent air column formation across the full rotation.

How This Fixture Is Commonly Used

Once installed, operators control fan speed through the wall-mounted VFD rather than at the fan itself. This allows adjustment from floor level or a designated control location without requiring access to the fan or ceiling structure. Speed changes take effect immediately, so airflow can be increased during warmer periods or reduced during cooler conditions or low-occupancy times.

The 38 dB operating sound level means the fan runs without contributing significant background noise. In spaces where communication or concentration matters, this allows continuous operation without disruption. Seasonal use typically involves running the fan in forward mode during warm months for direct cooling effect and at reduced speeds during colder months to destratify warm air collecting at ceiling level.

Safety, Certifications, and Warranty

The fan carries an IP55 rating. The controller carries an IP66 rating. These ratings define the level of protection against solid particles and water intrusion for each component.

LED Lighting Supply provides a 3-year warranty on the fan and a 2-year warranty on the VFD controller.
