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

Product Overview

This 24 Foot HVLS Ceiling Fan is engineered for large-scale air movement in expansive industrial and commercial interiors. With an 8-blade, 24-foot diameter design and a 3 HP gear drive motor, it is built to deliver high-volume, low-speed airflow for occupant comfort and energy efficiency. Typical installations include open floor plan environments such as warehouses, manufacturing plants, and aircraft hangars with mounting heights of 20 feet and above.

The fan includes a NEMA 1 wall-mounted VFD controller for variable speed operation, safety disconnect, and integrated safety features. It is suitable for mounting to I-Beams, Z-Purlins, or open joist structures. Minimum mounting height is 15 feet, with required ceiling and horizontal clearances for safe operation.

Core Performance and Output

This HVLS fan delivers up to 259,438 CFM at a maximum diameter of 24 feet, providing effective coverage for up to 25,000 square feet. The 3 HP motor and 8 aluminum blades are optimized for high-efficiency air movement at low rotational speeds (up to 62 RPM), maintaining sound levels below 59 dB. Variable speed control allows adjustment to match seasonal or occupancy needs.

Performance is consistent across a range of mounting heights, but output may be excessive for spaces under 15 feet or with significant obstructions. Uniform airflow is best achieved in open-plan layouts without dense racking or partitions. At maximum coverage, airflow uniformity may decrease at the perimeter of the coverage area.

Adjustability and Control Options

The included wall-mounted VFD controller provides variable speed adjustment, on/off toggle, and a safety disconnect. Speed can be set to match comfort requirements or energy management strategies. The controller is NEMA 1 rated for indoor use and supports both 208-240V and 460-480V three-phase power.

No integrated network or BMS connectivity is provided as standard. Control is local to the wall station. The fan supports reversible operation only if specified by the manufacturer; default configuration is standard forward airflow.

Longevity and Reliability

The fan is constructed with a 3 HP gear drive motor and aluminum blades for long-term durability in demanding environments. All joined components use dual-method fastening, and safety features include a safety cable, hub clips, hub retainer, and integrated sprinkler shut-off. The fan is designed for continuous operation in industrial settings.

Routine maintenance is limited to periodic inspection of mechanical fasteners and electrical connections. The system is covered by a 5-year warranty. Operating conditions outside recommended voltage or mounting requirements may affect longevity.

Build Quality and Physical Characteristics

The 24-foot diameter fan uses 8 extruded aluminum blades and weighs 262 lbs. Blade finish options include brushed aluminum, black, blue, or white. The downrod is 1 inch in diameter, and the fan requires a minimum ceiling clearance of 6?8 feet and a minimum horizontal clearance of 2 feet from obstructions.

Mounting hardware supports installation on I-Beams, Z-Purlins, or open joists. The fan is suitable for indoor use in dry, non-corrosive environments. Sound output remains below 59 dB at maximum speed, supporting use in occupied spaces.

Where This Product Fits Best

This HVLS fan is designed for large, open-plan industrial and commercial interiors where high-volume air movement is required for occupant comfort and energy efficiency. It is most effective in facilities with high ceilings and minimal obstructions.

• warehouse ventilation
• manufacturing facility ventilation
• aircraft hangar ventilation
• gymnasium ventilation
• distribution center ventilation
• convention center ventilation
• agricultural building ventilation
• large retail ventilation

Best suited for indoor environments with mounting heights above 15 feet and open floor layouts. Not intended for outdoor or corrosive atmospheres. Structural mounting points must support the fan?s weight and dynamic loads.

Installation and Long-Term Use

Installation requires structural mounting to I-Beams, Z-Purlins, or open joists with adequate load capacity. Minimum mounting height is 15 feet, with 6?8 feet of ceiling clearance and at least 2 feet of horizontal clearance from obstructions. Electrical connection supports 208-240V or 460-480V three-phase power.

Routine inspection of mounting hardware, safety cable, and electrical connections is recommended. The fan is designed for continuous operation and minimal maintenance. Access to the wall-mounted VFD controller should be maintained for safe operation and adjustment.

How This Fixture Is Commonly Used

Typical mounting heights range from 20 to 40 feet, depending on ceiling structure and desired airflow. Fans are often spaced to provide overlapping coverage in very large facilities, with one unit covering up to 25,000 square feet. In open-plan layouts, a single fan can serve a large zone, while multiple fans may be used for even air distribution.

Spacing and layout are determined by ceiling height, obstructions, and required comfort levels. Higher output allows for fewer fans, but may increase localized air movement near the fan center. Adjusting speed can help balance comfort and energy use.

Safety, Certifications, and Warranty

This HVLS fan includes integrated safety features: safety cable, hub clips, hub retainer, dual-method fastening, and sprinkler shut-off. The controller is NEMA 1 rated. The fan is designed for compliance with standard industrial safety practices for overhead equipment.

Warranty coverage is 5 years. All installation and operation must follow manufacturer guidelines for safety and performance. No additional third-party certifications are specified.
