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

Product Overview

This 20 foot HVLS ceiling fan uses eight aluminum blades and a 1.5 HP gear drive motor to deliver up to 183,620 CFM. The fan is designed for large, open commercial and industrial spaces requiring high-volume air movement.

Variable speed control is managed through a wall-mounted VFD controller with integrated safety disconnect, on/off toggle, and speed regulator. The fan operates at a maximum of 49 RPM and maintains a sound level below 59 dBA.

Available in brushed aluminum, black, blue, or white, the fan weighs 218 lbs and is compatible with multiple mounting types, including I-beam, Z-purlins, and open joist structures. Downrod extensions are available in 1, 2, 3, and 6 foot lengths to accommodate different ceiling heights.

Minimum mounting requirements include a 15 foot ceiling height, 3-4 feet of ceiling clearance, and 2 feet of horizontal clearance from obstructions.

Where This Product Fits Best

This fan is suited for large-scale environments such as warehouses, manufacturing plants, distribution centers, aircraft hangars, and gymnasiums. The 19,750 square foot coverage area supports use in open floor plans where broad, even air movement is needed.

It is appropriate for facilities with ceiling heights of at least 15 feet and where structural mounting to I-beams, Z-purlins, or open joists is possible. The fan is not intended for low-ceiling or confined spaces due to its size and clearance requirements.

Applications that benefit from high airflow and low noise, such as workshops and assembly areas, are a good fit. The fan?s color options allow for integration with facility aesthetics where needed.

Performance and Functional Considerations

The 1.5 HP gear drive motor and eight-blade design provide consistent, high-volume airflow across large areas. The fan delivers up to 183,620 CFM at a maximum speed of 49 RPM, supporting occupant comfort and air circulation in demanding environments.

Variable speed control through the wall-mounted VFD allows for adjustment based on seasonal or operational needs. The sound level remains below 59 dBA, minimizing disruption in occupied spaces.

Voltage compatibility includes 208V-240V and 460V-480V three-phase, as well as 110V-120V single-phase. Amperage draw is 1.90 A at 208-240V 3P and 0.95 A at 460-480V 3P. The fan operates at 60 Hz.

Minimum mounting height, ceiling clearance, and horizontal clearance must be maintained for safe and effective operation. The fan?s weight and size require secure structural mounting.

Installation and Long-Term Use

The fan is designed for mounting to I-beams, Z-purlins, or open joists. Downrod extensions in multiple lengths support installation at varying ceiling heights while maintaining required clearances.

All joined components use dual-method fastening, and safety features include a safety cable, hub clips, hub retainer, and integrated sprinkler shut-off. These features support safe installation and operation in active facilities.

The wall-mounted VFD controller provides direct access to speed and on/off functions. The fan?s aluminum blades and gear drive motor are built for long-term use in industrial environments.

Routine inspection of mounting hardware and safety features is recommended as part of ongoing facility maintenance.

How This Fixture Is Commonly Used

Once installed, the fan is typically set to a speed that matches the comfort or air movement needs of the space. The wall-mounted VFD controller allows you to adjust speed as conditions change, such as during seasonal transitions or when occupancy levels vary.

Facility operators rely on the fan to maintain consistent air movement across large open areas, reducing stagnant zones and supporting occupant comfort. The low sound level allows the fan to run during working hours without interfering with communication or workflow.

Color options can be selected to match facility branding or visibility requirements. The fan?s safety features are designed to operate passively, requiring only periodic checks as part of standard maintenance routines.

Safety, Certifications, and Warranty

Safety features include a safety cable, hub clips, hub retainer, dual-method fastening, and integrated sprinkler shut-off. These are built into the fan for operational safety in commercial and industrial environments.

LED Lighting Supply provides a 5 year warranty on this fan.
