78 Inch Drum Fan | 43,370 CFM | 110-120V

Product Overview

This is a 16 foot diameter HVLS ceiling fan with five aluminum blades and a direct drive 800 watt PMSM motor. The fan is designed for large open spaces and provides variable speed operation from 25 to 75 RPM.

The fan is controlled by a wall-mounted VFD and includes a remote control for speed adjustment. It operates on single phase power and supports both 208V-240V and 277V-480V voltage ranges.

The standard finish is available in black or silver. The fan weighs 120 lbs and comes with a 59 inch downrod, with custom downrod lengths available.

Sound output is rated below 40 dBA during operation. The fan is rated for use in environments requiring IP57 protection.

Where This Product Fits Best

This fan is suitable for large commercial and industrial spaces where air movement is needed across areas up to 6,400 square feet. Typical applications include warehouses, manufacturing floors, distribution centers, and sports venues.

The IP57 rating allows installation in locations where dust and water exposure are present, such as facilities with open loading bays or areas subject to periodic washdown.

The fan is compatible with I-beam mounting, which is common in steel-structured buildings and open truss ceilings. The 16 foot diameter is intended for spaces with sufficient ceiling height and clearance for safe blade rotation.

Variable speed control supports both high and low airflow requirements, making the fan suitable for year-round use in temperature management and occupant comfort.

Performance and Functional Considerations

The 800 watt PMSM direct drive motor delivers consistent torque and quiet operation. The fan operates at speeds from 25 to 75 RPM, allowing adjustment for different airflow needs.

With a coverage area of 6,400 square feet, this fan is intended for large, open-plan spaces. The five-blade design balances airflow and efficiency while maintaining a sound level below 40 dBA.

The fan draws 2.0 amps at 220V and supports both 208V-240V and 277V-480V input voltages. This allows integration into a range of electrical systems found in commercial and industrial facilities.

The wall-mounted VFD controller and remote provide direct speed adjustment from the floor or control room. The aluminum blades are designed for durability and corrosion resistance in demanding environments.

Installation and Long-Term Use

The fan is designed for I-beam mounting, which is standard in many industrial and commercial buildings. The 59 inch downrod provides adequate drop for most high-bay installations, with custom lengths available for site-specific requirements.

At 120 lbs, the fan requires secure mounting and proper structural support. The IP57 rating allows for installation in areas exposed to dust and water, supporting long-term reliability in challenging environments.

Variable speed control is managed through the wall-mounted VFD and remote, allowing for adjustment without accessing the fan directly. The direct drive motor reduces maintenance requirements compared to belt-driven systems.

Aluminum blades resist corrosion and are suitable for use in humid or partially exposed locations. Routine inspection of mounting hardware and electrical connections is recommended for ongoing safety and performance.

How This Fixture Is Commonly Used

Once installed, the fan is typically set to a speed that matches the airflow needs of the space. You can adjust the speed using the wall-mounted VFD controller or the included remote, depending on seasonal requirements or occupancy levels.

The fan operates quietly, with sound output below 40 dBA, so it does not interfere with normal activities or communication on the floor. The five-blade design provides steady, even air movement across the coverage area.

In facilities where dust or water exposure is a concern, the IP57 rating allows the fan to remain in operation during cleaning or in areas with airborne particulates. The aluminum blades and direct drive motor require minimal ongoing attention.

Custom downrod lengths can be specified to achieve the correct mounting height for your ceiling structure, ensuring safe clearance and optimal airflow. The fan is typically left running for extended periods to maintain consistent air movement.
