The Super Duty SD20HO is the Workhorse of our industrial HVLS lineup and it moves more air than existing 24 ft. fans on the market. The 1500-Watt motor and the VFD with 220-Volt single phase input, not to mention the innovative telescoping down rod and the 6 high-tech blades with dual hubs, offer an unbeatable performance at a fraction of the price of other fans. Bigger is not always better. Smarter is better.
Cutting-edge blade design maximizes airflow and minimizes noise
Leading-edge vortex generators and rake blade tips boost air flow
High-efficiency direct drive PMSM Motor with extended life
Artificial intelligence (AI) assisted blade design for a highly-complex blade shape with perfected fluid dynamics
Each blade is constructed of injection-molded polymers (proprietary composition) with 30 patent-pending features including trailing-edge graduated serrations, leading-edge Vortex Generators (VG's), raked blade tip and complex built-in pitch contours
Universal ceiling mount included to allow for an easy installation to varying ceiling structures
Each fan mount has 4 loops to accept a guy wire system, optional on the 7 ft and 10 ft models, included on all HO models, wires are 9 ft long
Efficient PMSM state-of-the-art motor and digital VFD (included) for huge torque, with no massive gearbox required
