Super Duty Fans SD15 High-Volume, Low-Speed 3 Blades Ceiling Fan
SD15 3-Blade HVLS Ceiling Fan by Super Duty Fans
The SD15 3-Blade Ceiling Fan from Super Duty Fans delivers exceptional performance and efficiency with fewer components. Powered by a robust 750-watt Permanent Magnet Synchronous Motor, this 15’ HVLS fan generates airflow equal to or greater than 5-blade models, thanks to its advanced aerodynamic blade design. Operating quietly at up to 85 RPM, it’s ideal for warehouses, gymnasiums, shops, or any facility seeking reliable airflow with minimal energy usage.
Despite its large coverage area of 12,300 ft², installation is quick and straightforward with the telescoping down rod and factory pre-assembled blades and hubs. The included VFD controller runs on standard 110V, converting input to 220V 3-phase power for efficient motor operation, while offering smooth, reversible speed control. Optional guy wire kit available for enhanced stability.
