Product Overview
This 20-foot HVLS ceiling fan is designed to move air across large indoor spaces using six aluminum blades and a 1.5 HP PMSM motor. It delivers up to 406,119 CFM at variable speed.
The fan has a 10,700 square foot coverage area and a 39-inch downrod for suspended ceiling installation. Its 297-pound weight and 20-foot diameter require confirmation of the supporting structure before installation.
Core Performance and Output
The 1100-watt motor operates at up to 65 RPM and produces up to 406,119 CFM. Variable speed operation allows airflow to be adjusted for changing conditions within the space.
The fan operates on 208V-240V or 380V-480V power at 50/60 Hz and is available for single-phase or three-phase service. The PMSM motor supports controlled low-speed airflow across a broad coverage area.
The 20-foot blade diameter can be excessive in areas with limited ceiling clearance or obstructions. Coverage and airflow distribution depend on ceiling height, structural placement, and surrounding equipment.
Adjustability and Control Options
A wall-mounted VFD controller provides variable speed control. The controller has an IP66 rating.
Variable speed operation allows facility personnel to reduce or increase airflow as operating conditions change. Controller location should remain accessible for normal operation and service.
Longevity and Reliability
The fan uses aluminum blades and a PMSM motor. The fan housing has an IP55 rating.
The controller is rated IP66. The product includes a 2-year warranty.
Build Quality and Physical Characteristics
This fan has a 20-foot diameter, six aluminum blades, and a silver finish. The assembled fan weight is 297 pounds.
A 39-inch downrod is included. The downrod length, blade diameter, and fan weight must be considered with ceiling clearance and structural support conditions.
Where This Product Fits Best
This fan fits large indoor environments where broad, low-speed air movement is needed across open floor areas. Its coverage area and 20-foot diameter align with large-scale ventilation layouts.
- warehouse ventilation
- manufacturing facility ventilation
- distribution center ventilation
- aircraft hangar ventilation
- agricultural building ventilation
- livestock facility ventilation
The IP55 fan rating supports use where the fan requires protection from dust and water exposure. The IP66 wall controller provides a higher enclosure rating for the control component.
Installation and Long-Term Use
Installation requires a ceiling location that can support the 297-pound fan assembly and accommodate the 20-foot blade sweep. The 39-inch downrod establishes the suspended position below the mounting point.
Electrical service must match the selected 208V-240V or 380V-480V configuration and available single-phase or three-phase power. The wall-mounted VFD controller should be placed where operating staff can access it.
Long-term service includes keeping the blade area clear and maintaining access to the controller. Ceiling obstructions and changes to the surrounding layout can affect airflow distribution.
How This Fixture Is Commonly Used
In warehouse ventilation, manufacturing facility ventilation, and distribution center ventilation layouts, the fan is positioned over open areas to create broad airflow coverage. The 20-foot diameter requires clear space around the blade path and below the suspended fan.
For aircraft hangar ventilation, agricultural building ventilation, and livestock facility ventilation, placement is based on the available ceiling structure, occupied zones, and obstructions within the space. Fan speed is adjusted through the wall-mounted VFD controller.
Higher speed increases airflow output, while final placement depends on ceiling height, layout requirements, and the 10,700 square foot coverage area.
Safety, Certifications, and Warranty
The fan is rated IP55. The wall-mounted VFD controller is rated IP66.
The fan operates on 208V-240V or 380V-480V power at 50/60 Hz. The warranty period is 2 years.
