20 Foot HVLS Ceiling Fan | 8 Blades | 19,750 Square Foot Coverage | 183620 CFM
This 20 foot HVLS ceiling fan is a strong choice for large, open commercial and industrial spaces needing reliable, high-volume air movement, thanks to its eight aluminum blades, 1.5 HP gear drive motor, and up to 183,620 CFM output. The wall-mounted VFD controller allows precise speed adjustment and includes integrated safety features, supporting both operational flexibility and facility safety. Its low sound level (below 59 dBA) minimizes disruption in occupied areas. Ideal applications include warehouses, manufacturing plants, distribution centers, aircraft hangars, and gymnasiums with ceilings at least 15 feet high. It is not suitable for low-ceiling or confined spaces.

Product Overview
This 20-foot HVLS ceiling fan is designed to move air across large interior floor areas with an 8-blade aluminum assembly and 1.5 HP gear-drive motor. It delivers up to 183,620 CFM at 49 RPM.
The fan is configured for warehouse ventilation and manufacturing facility ventilation where overhead mounting structure can support a 218-pound fan assembly. Its stated coverage area is 19,750 square feet.
Core Performance and Output
At maximum speed, the fan produces 183,620 CFM at 49 RPM. Variable-speed operation allows airflow to be reduced for changing occupancy, process, or seasonal conditions.
The fan operates on 60 Hz power and is available for 110-120V, 208-240V, and 460-480V systems with 1-phase or 3-phase configurations. Listed 3-phase current draw is 1.90 A at 208-240V and 0.95 A at 460-480V.
The 20-foot diameter and stated coverage area suit large open layouts. Building obstructions, structural bays, and other overhead equipment affect actual air distribution across the floor.
Adjustability and Control Options
A wall-mounted NEMA 1 VFD controller is included. The controller provides a safety disconnect, on/off toggle, and speed regulator.
Variable speed allows the fan output to be adjusted without changing the fan configuration. The controller location should remain accessible for facility personnel while staying clear of normal traffic and work activity.
Longevity and Reliability
The fan uses a 1.5 HP gear-drive motor and aluminum blades. The assembly includes dual-method fastening for joined components.
A safety cable, hub clips, and hub retainer are included as part of the safety system. The fan carries a 5-year warranty.
Build Quality and Physical Characteristics
The fan has an 8-blade aluminum configuration with a 20-foot diameter. Available finishes are brushed aluminum, black, blue, and white.
The complete fan weighs 218 pounds and uses a 1-inch downrod. Mounting options include I-beam, Z-purlin, and open joist structures.
Where This Product Fits Best
This fan fits large enclosed facilities that need broad overhead air movement and have adequate ceiling height and structural support. The minimum mounting height is 15 feet.
- warehouse ventilation
- manufacturing facility ventilation
- distribution center ventilation
- aircraft hangar ventilation
- gymnasium ventilation
- agricultural building ventilation
The installation area requires 3 to 4 feet of minimum ceiling clearance and 2 feet of minimum horizontal clearance. The fan includes integrated sprinkler shut-off.
Installation and Long-Term Use
Install the fan on an I-beam, Z-purlin, or open joist structure that supports the fan weight and installed assembly. Confirm the selected voltage, phase, mounting structure, and required clearances before installation.
Maintain at least 15 feet of mounting height, 3 to 4 feet of ceiling clearance, and 2 feet of horizontal clearance. The wall-mounted VFD should be positioned where its disconnect, on/off control, and speed regulator can be safely accessed.
How This Fixture Is Commonly Used
In warehouse ventilation, manufacturing facility ventilation, and distribution center ventilation layouts, the fan is mounted above open floor areas with clearance around the blade sweep. Placement is coordinated with structural members and sprinkler components.
For gymnasium ventilation, aircraft hangar ventilation, and agricultural building ventilation, fan layout follows available mounting points and open floor geometry. Higher fan output can cover a larger area, but building obstructions and layout requirements affect final placement.
Safety, Certifications, and Warranty
The included wall-mounted VFD is NEMA 1. Safety features include a safety cable, hub clips, hub retainer, dual-method fastening of joined components, and integrated sprinkler shut-off.
The fan includes a 5-year warranty. Maintain the installed clearances and mounting arrangement throughout the service life of the fan.
