There are lots of “Industrial” fans on the market today. They might look good on the website, but most don’t move enough air and will not survive in a tough environment. There are better quality options available but they can be extremely expensive or too large or inflexible for your space. Super Duty Fans are durable, affordable AND they move big air. Our fans are the smarter solution for your cooling needs.

Serious Fans Have Shrouds!

What they are saying!

  • Scott A. Miami FL

    My employees are happier, and my employee turnover is lower since I installed two of the SD5XL fans in my manufacturing facility. I highly recommend them!
  • Paul S. Des Moines, IA

    We hung 6 of the Super Duty Fans in my dairy barn and the difference was night and day. We plan to add more to other barns before summer. These fans are well-built and move a lot of air, and I recommend them.
  • Richard M. Houston, TX

    The summers inside my airplane hangar were unbearable, so we bought a SD5XL fan and hung it in the middle of our 60’ x 65’hangar. It moves air throughout the entire building, and we can work on the airplanes in July with no problem. This was a lot less money than those big fans, they move more air, and the quality is excellent.
