Super Duty Fans SD7 High-Volume, Low-Speed 3 Blades Ceiling Fan
SD7 High-Volume, Low-Speed 3 Blades Ceiling Fan by Super Duty Fans
Compact yet incredibly powerful, the SD7 3-Blade Ceiling Fan is designed to deliver high-performance airflow in tighter or lower-ceiling spaces. Despite its smaller 7-foot diameter, it utilizes the same cutting-edge technology as its larger counterparts—including a 400-watt Permanent Magnet Synchronous Motor (PMSM), energy-efficient operation, and a full-featured Variable Frequency Drive (VFD) controller. This ceiling fan is perfect for workshops, garages, retail spaces, or smaller industrial areas where efficient air movement is still a priority.
Each of the three high-tech blades features a proprietary polymer composition and 30 patent-pending elements that optimize performance and minimize noise. These include trailing-edge graduated serrations, leading-edge vortex generators, and a raked blade tip. The result is a quiet yet powerful fan that effectively distributes airflow over a wide 45-foot radius.
Installation is designed to be fast and user-friendly. The blades come pre-balanced and pre-assembled with attachment arms, and the down rod features a telescoping design that eliminates the need for custom cutting or drilling. The included wall-mounted VFD controller requires just 110V input, converting it to 220V 3-phase to drive the motor. Speed and direction (reversible) are adjustable, with soft ramp-up settings to protect the fan and circuit.
