The Super Duty SD20HO is the workhorse of our HVLS (High-Volume, Low-Speed) ceiling fan lineup, engineered to outperform even 24-foot models with smarter design. Its 1,500 W Permanent Magnet Synchronous Motor (PMSM) and integrated variable frequency drive (VFD) convert standard 220 V single-phase input into seamless 3-phase power, delivering up to 55 RPM with minimal amp spikes. The six dual-hub blades, injection-molded from a proprietary polymer, feature 30 patent-pending refinements—from trailing-edge serrations and leading-edge vortex generators to raked tips and built-in pitch contours—for maximum airflow across 22,650 ft². A telescoping down rod eliminates cutting or drilling, and the rugged guy-wire system ensures stability in even the most demanding industrial environments.
Durability and versatility are built in. The IP20 controller (upgradeable to IP67) offers on/off, variable-speed, and reversible airflow, accepts fire-suppression relays, and mounts neatly on any wall. Hubs and down rods arrive in sleek aluminum, while the motor and mounts sport a satin-black finish; blades ship in black but can be custom-painted in high-adhesion colors for large orders. Pre-assembly of blades, hubs, and mounting hardware streamlines installation.

Forklifts and Lift Gates
All of our Single Post, 2 Post, and 4 Post Lifts* require a forklift (or similar) to unload. Tire Changers and Balancers and other small items allow for a lift gate service (At no additional charge) Lift gate service will lower your order to street level. How do I know if a forklift is required? See the drop down options that show when you're attempting to place an order.
What if I don't have a forklift at my location and my order requires it?
This is a common question and here's some alternatives:
Can I hand unload my order if I don't have a forklift?
No, sorry, the truck drivers don't allow for this. 2 things: Liabilities and the time it takes to unload - truck drivers can't wait, even if you have an army of help.

Freight Terminals
If you don't have a forklift at your location, we can find you a freight terminal in your area and they will load your trailer onsite. (Typically 30-60 minute drive away, depending on location) Special note: Some orders are so large they ship on a flatbed by themselves, in these cases a freight terminal delivery is not an option. The product page will state whether this is the case.
