Product Overview
This is a 20 foot diameter HVLS ceiling fan with 8 aluminum blades. It is designed for large commercial and industrial spaces requiring high-volume, low-speed air movement. The fan delivers up to 183,620 CFM and covers up to 19,750 square feet.
The fan uses a 1.5 HP gear drive motor and operates at a maximum speed of 49 RPM. Variable speed control is provided through a wall-mounted NEMA 1 VFD controller. The fan is available in brushed aluminum, black, blue, or white finishes.
Mounting options include I-beam, Z-purlins, and open joist structures. Minimum mounting height is 15 feet, with a required ceiling clearance of 3-4 feet and a minimum horizontal clearance of 2 feet.
The fan weighs 218 lbs and operates at a sound level below 59 dB.
Where This Product Fits Best
This HVLS ceiling fan is suited for large open areas such as warehouses, manufacturing plants, distribution centers, and gymnasiums. It is intended for spaces where consistent air movement is needed across wide floor areas.
Facilities with high ceilings and structural support for I-beam, Z-purlin, or open joist mounting can accommodate this fan. The minimum mounting height and clearance requirements must be met for safe and effective operation.
Applications include temperature equalization, occupant comfort, and air circulation in environments where traditional high-speed fans are not practical or effective.
Performance and Functional Considerations
The fan provides variable speed operation through a wall-mounted VFD controller. This allows adjustment of airflow to match seasonal or operational needs.
With a maximum output of 183,620 CFM, the fan is capable of moving large volumes of air at low speeds, reducing noise and minimizing draft discomfort. The sound level remains below 59 dB during operation.
Voltage compatibility includes 208V-240V and 460V-480V three-phase, as well as 110V-120V single-phase. The fan draws 1.90 A at 208-240V 3-phase and 0.95 A at 460-480V 3-phase.
The 1.5 HP gear drive motor is designed for continuous operation in demanding environments. The aluminum blades are corrosion-resistant and suitable for industrial use.
Installation and Long-Term Use
Mounting options support installation on I-beams, Z-purlins, or open joists. The fan requires a minimum mounting height of 15 feet, with at least 3-4 feet of ceiling clearance and 2 feet of horizontal clearance from obstructions.
The fan is supplied with a 1 inch downrod and weighs 218 lbs. Structural assessment is recommended to confirm load capacity before installation.
The wall-mounted VFD controller includes a safety disconnect, on/off toggle, and speed regulator. All joined components use dual-method fastening for added security.
Long-term use is supported by a 5-year warranty and integrated safety features, including a safety cable, hub clips, hub retainer, and sprinkler shut-off integration.
How This Fixture Is Commonly Used
After installation, the fan is operated using the wall-mounted VFD controller. You can adjust the speed to increase or decrease airflow as needed for occupant comfort or process requirements.
The fan is typically left running during occupied hours to maintain consistent air movement. The low-speed operation helps avoid disruptive drafts while still providing coverage across large areas.
Routine checks of the safety cable, hub clips, and fastening points are recommended as part of regular maintenance. The integrated sprinkler shut-off is designed to work with fire protection systems where required.
Color options allow the fan to match facility aesthetics or safety color coding as needed.
Safety, Certifications, and Warranty
The fan includes a safety cable, hub clips, hub retainer, and dual-method fastening for all joined components. An integrated sprinkler shut-off is provided for compatibility with fire protection systems.
The controller features a safety disconnect for lockout/tagout procedures. The fan is covered by a 5-year warranty from LED Lighting Supply.
