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 blades look different from anything you've seen before because they perform better than anything you've ever seen. 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
