20 Foot HVLS Ceiling Fan | 6 Blades | 19,750 Square Foot Coverage | 137,000 CFM

Product Overview

This is a 16 foot diameter, 6-blade HVLS ceiling fan designed for large, open commercial and industrial spaces. The fan delivers up to 70,000 CFM and covers up to 12,750 square feet. It operates at a maximum speed of 44 RPM and produces less than 57 dBA at full speed.

The fan uses a 0.5 HP gear drive motor and supports both single-phase and three-phase power. Voltage compatibility includes 110-120V, 208-240V, and 460-480V. The fan is controlled by a NEMA 1 wall-mounted VFD with integrated safety disconnect, on/off toggle, and speed regulator.

Blade construction is aluminum, finished in black. The fan weighs 126 lbs. Downrod extensions are available in 1, 2, 3, and 6 foot lengths to accommodate different ceiling heights and mounting requirements.

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 suitable for large, open-plan environments where consistent air movement is needed across wide areas. Typical applications include warehouses, manufacturing facilities, distribution centers, aircraft hangars, and large workshops.

It is also used in commercial gyms and similar spaces where high ceilings and open layouts require broad air circulation. The fan?s coverage area and CFM output are designed for spaces up to 12,750 square feet.

Minimum mounting height is 10 feet, with at least 6 feet of ceiling clearance and 2 feet of horizontal clearance required. The fan can be mounted to I-beams, Z-purlins, or open joists, supporting a range of structural conditions.

Variable speed control allows adjustment for seasonal or operational needs, making it suitable for environments with changing occupancy or process requirements.

Performance and Functional Considerations

The fan?s 70,000 CFM output supports air movement in large, open spaces. The 6-blade aluminum design balances airflow and sound, with a maximum sound level below 57 dBA.

Variable speed operation is managed through the wall-mounted VFD controller. The controller includes a safety disconnect, on/off toggle, and speed regulator for direct adjustment at the installation site.

Compatible with both single-phase and three-phase power, the fan can be integrated into a range of electrical systems. Amperage varies by voltage and phase, with the highest draw at 110-120V single-phase (9.6A) and lowest at 460-480V three-phase (1.8A).

Minimum mounting and clearance requirements must be met for safe and effective operation. Downrod extensions allow for installation flexibility based on ceiling height and obstructions.

Installation and Long-Term Use

The fan is designed for mounting to I-beams, Z-purlins, or open joists. Downrod extensions in 1, 2, 3, and 6 foot lengths are available to accommodate different ceiling heights and clearances.

Minimum mounting height is 10 feet. At least 6 feet of clearance from the ceiling and 2 feet of horizontal clearance from obstructions are required for safe operation.

The wall-mounted VFD controller provides direct access for speed adjustment and includes a safety disconnect. All joined components use dual-method fastening, and additional safety features include a safety cable, hub clips, and hub retainer.

Integrated sprinkler shut-off is included for compatibility with fire protection systems. The fan?s aluminum blades and gear drive motor are designed for long-term use in commercial and industrial environments.

How This Fixture Is Commonly Used

Once installed, the fan is typically set to run at a speed appropriate for the space and occupancy. The wall-mounted VFD controller allows you to adjust speed as needed for seasonal changes or operational shifts.

Facility staff can use the on/off toggle and speed regulator directly at the controller location. The fan?s low sound output supports use in occupied spaces without significant noise disruption.

Routine checks of the safety cable, hub clips, and fastening points are recommended as part of standard maintenance. The integrated sprinkler shut-off supports compliance with fire protection protocols in facilities where required.

Downrod length and mounting method are selected during installation to ensure proper clearance and airflow. After setup, the fan operates with minimal intervention beyond periodic inspection and cleaning.
