24 Foot HVLS Ceiling Fan | 8 Blades | 25,000 Square Foot Coverage | 259,438 CFM

Product Overview

This is a 24-foot diameter HVLS ceiling fan with eight aluminum blades, delivering 259,438 CFM at a maximum speed of 62 RPM. The fan is powered by a 3 HP gear drive motor and operates on three-phase power at either 208-240V or 460-480V. Total fixture weight is 262 lbs.

A NEMA 1 wall-mounted VFD controller is included with the fan. The controller provides a safety disconnect, on/off toggle, and variable speed regulation. The fan operates at a sound level under 59 dBA at full speed.

Color options include Brushed Aluminum, Black, Blue, and White. Downrod extensions are available in 1 ft, 2 ft, 3 ft, and 6 ft lengths to accommodate varying ceiling heights and structural conditions.

Where This Product Fits Best

This fan is sized for large open floor plans requiring air movement across areas up to 25,000 square feet. Typical environments include warehouses, manufacturing facilities, distribution centers, hangars, gymnasiums, workshops, and factories.

Minimum mounting height is 15 feet. Ceiling clearance between the fan and the structure above must be at least 6-8 feet. Horizontal clearance from walls, columns, or obstructions must be at least 2 feet from the blade tips.

Three-phase electrical service is required. Facilities with 208-240V service will see approximately 12A draw; facilities with 460-480V service will see approximately 6A draw. Operating frequency is 60 Hz.

Performance and Functional Considerations

At 259,438 CFM, this fan moves a substantial air volume at low rotational speed. The eight-blade configuration and 24-foot sweep generate broad, consistent airflow across the coverage area without the turbulence or concentrated drafts associated with smaller high-speed fans.

The 3 HP gear drive motor sustains output at variable speeds controlled through the wall-mounted VFD. Speed adjustment allows operators to balance airflow intensity with occupant comfort or process requirements as conditions change throughout the day or season.

Sound output remains below 59 dBA, which is relevant in occupied spaces where excessive fan noise would interfere with communication or work activities.

Installation and Long-Term Use

Mounting hardware supports I-beam, Z-purlin, and open joist configurations. The appropriate downrod length should be selected based on ceiling height and the required clearance between the blade plane and the floor or occupied zone. Available downrod lengths are 1 ft, 2 ft, 3 ft, and 6 ft.

At 262 lbs total weight, structural load capacity of the mounting point must be verified before installation. All joined components use dual-method fastening. Additional safety provisions include a safety cable, hub clips, and hub retainer.

An integrated sprinkler shut-off is included for installations where fire suppression systems are present. This feature allows the fan to stop automatically when sprinkler activation is detected.

How This Fixture Is Commonly Used

Once installed, speed is adjusted using the wall-mounted VFD controller. Operators typically increase airflow during warmer periods or when the space is at higher occupancy and reduce speed during cooler conditions or unoccupied hours. The variable speed control allows the fan to run continuously at lower output without excessive energy draw or noise.

In warehouse and manufacturing environments, facilities often run the fan at moderate speed during shifts to support thermal comfort and air circulation without creating drafts that disturb lightweight materials or interfere with processes. In gymnasiums and hangars, speed is adjusted based on activity levels and seasonal temperatures.

Maintenance access for the motor and hub is from floor level using appropriate lift equipment. The aluminum blades do not require lubrication or seasonal adjustment.

Safety, Certifications, and Warranty

Safety features include a safety cable, hub clips, hub retainer, dual-method fastening on all joined components, and an integrated sprinkler shut-off. The wall-mounted VFD includes a safety disconnect.

This fan carries a 5-year warranty.
