SD20HO High-Volume, Low-Speed Ceiling Fan by Super Duty Fans

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:

  • We can deliver to a local freight terminal near you.  Typically this is within 30-60 minutes away depending on location.  We will find a location - Contact Us
  • Do you have a buddy that owns a forklift and we can ship it there?  Does your place of work have a forklift?  Select this location as the delivery address. 
  • Warehouse pickup - This is always an option but depends how far you're willing to drive. 
  • Rent a forklift - This is the least favorable option but may be necessary.  We always schedule the delivery so this should minimize the days required to rent.

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. 

How do I know if my order requires a forklift or if a lift gate service is available?

See the drop down options that show when you're attempting to place an order. 

Residential Deliveries

Yes, we deliver to residential addresses!

Will the freight company contact me to schedule the delivery?

Yes, the freight company will call you ahead of time to schedule the delivery to ensure you are available to receive/unload your order. 

Warehouse Pickup (No Freight Charge)

Warehouse pickup is available for almost all of our brands.  Warehouse locations are listed on each product page.  At checkout, select "Pickup" and choose the warehouse you'd like to pickup from.  Upon ordering, we will send an email with the pickup form/number. 

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. 

Flat Rate Shipping and Freight Quotes

Most of our products have a flat rate shipping fee. However, if you see a note that says "Contact us to see if we can ship for less" then this means we're able to quote for a better price.  Contact Us now!
