20 Foot HVLS Ceiling Fan | 8 Blades | 19,750 Square Foot Coverage | 183620 CFM

Product Overview

This is a 20 foot diameter, 8-blade HVLS ceiling fan designed for large-scale air movement in commercial and industrial environments. The fan delivers up to 183,620 CFM and covers up to 19,750 square feet.

The fan operates with a variable speed drive and is compatible with both single-phase and three-phase power. The motor is a 1.5 HP gear drive. The fan is available in brushed aluminum, black, blue, or white finishes.

Blade construction is aluminum for durability and reduced weight. The fan is controlled by a wall-mounted VFD with integrated safety disconnect, on/off toggle, and speed regulator.

Safety features include a safety cable, hub clips, hub retainer, dual-method fastening for all joined components, and an integrated sprinkler shut-off.

Where This Product Fits Best

This fan is suited for large open spaces where high-volume, low-speed air movement is needed. Typical applications include warehouses, manufacturing facilities, distribution centers, aircraft hangars, and gyms.

Minimum mounting height is 15 feet, with a required ceiling clearance of 3 to 4 feet and a minimum horizontal clearance of 2 feet. The fan weight is 218 lbs, so structural support must be verified before installation.

Mounting options include I-beam, Z-purlins, and open joist structures. Downrod extensions are available in 1, 2, 3, and 6 foot lengths to accommodate varying ceiling heights and obstructions.

Sound level is below 59 dBA, which supports use in environments where low noise is important.

Performance and Functional Considerations

The fan provides up to 183,620 CFM at a maximum speed of 49 RPM. This output is suitable for moving large volumes of air across expansive floor areas.

Variable speed control allows adjustment to match seasonal requirements or occupant comfort. The wall-mounted VFD controller provides direct access to speed settings and includes a safety disconnect.

Power requirements are 208-240V or 460-480V three-phase, and 110-120V single-phase. Amperage draw is 1.90A at 208-240V three-phase and 0.95A at 460-480V three-phase.

Blade material is aluminum, which resists corrosion and reduces overall fan weight for easier handling during installation.

Installation and Long-Term Use

The fan is designed for mounting to I-beams, Z-purlins, or open joist structures. Downrod extensions in multiple lengths allow for flexibility in positioning based on ceiling height and obstructions.

Minimum mounting height is 15 feet. Ensure at least 3 to 4 feet of clearance above the fan and 2 feet of horizontal clearance from any obstruction.

All joined components use dual-method fastening for added security. Safety cable, hub clips, and hub retainer are included as standard safety measures.

The integrated sprinkler shut-off is included for compatibility with fire suppression systems. The fan is controlled by a wall-mounted VFD, which should be installed in an accessible location for daily operation and maintenance.

How This Fixture Is Commonly Used

Once installed, the fan is typically set to a speed that matches the comfort or ventilation needs of the space. The wall-mounted VFD controller allows you to adjust speed as needed throughout the year.

In large open areas, the fan helps maintain consistent air movement, reducing temperature stratification and improving occupant comfort. The low sound level supports use in environments where noise is a concern.

Blade and motor design allow for continuous operation in demanding environments. The aluminum blades are easy to clean and maintain, and the gear drive motor is built for long-term reliability.

Safety features such as the integrated sprinkler shut-off and dual-method fastening are in place to support ongoing compliance and operational safety in active facilities.

Safety, Certifications, and Warranty

Safety features include a safety cable, hub clips, hub retainer, dual-method fastening, and integrated sprinkler shut-off.

The fan is supplied with a 5-year warranty from LED Lighting Supply.

All safety and operational features are built into the fan as standard.
