For 20 years, Big Ass industrial fans have set the standard for powerful, efficient airflow that transforms uncomfortable facilities and lowers overhead costs. We led the way with direct-drive technology 10 years ago; now we’re pacing the field with Powerfoil D, the only direct-drive overhead fan purpose-built for harsh industrial conditions. In the hot, dusty environments that put competitors’ fans out of commission, Powerfoil D thrives with cool, quiet operation.
Have an off-brand fan that can’t get the job done? With our trade-up program, we’ll give you credit for that “other” fan when you upgrade to an authentic Big Ass Fans product.
Big Ass Fans was forged in industrial conditions, so we fully appreciate the need for products that promote and maintain safe operations in tough environments. That’s why no other industrial fan has more redundant safety features than Powerfoil D.
The patented Airfoil Restraint System suspends your fan’s airfoils in the event of severe impact damage. Featuring durable nylon straps that extend from hub to winglet, the Airfoil Restraint System is standard on 20- and 24-foot models (available upon request for smaller diameters) and keeps people, products, and property out of harm’s way.
We knew that to have the first direct-drive overhead fan to withstand industrial abuse, we’d have to design and purpose-build it ourselves. We didn’t use off-the-shelf components or rely on outside engineers to do what we do best; we developed an all-new drive and motor and created the only overhead fan that comes standard with an IP66 rating and max temperature rating of 131 °F (55 °C).
Powerfoil D has the size and muscle to create high-volume airflow, but it’s not all brawn; its Neodymium magnet motor runs quietly and with incredible efficiency, so there’s no mechanical noise to distract people in your space. The airflow from Powerfoil D makes occupants feel up to 10 °F (6 °C) cooler in summer, and in winter gently recirculates the heated air trapped at the ceiling back down where people need it.

We purpose-built Powerfoil D for industrial spaces, but its feature-rich design is a handsome suit for nearly any commercial or public application. Its sleek aesthetic and virtually silent operation are perfect for restaurants, retail spaces, fitness centers, and outdoor venues. A wide range of diameters and mounting options make it great as a retrofit or for new construction, while its static output shaft supports a variety of functional attachments.
Powerfoil D is pre-programmed to integrate with your fire suppression and building automation systems (0-10 VDC, Modbus standard), so there’s no time-consuming setup. Just mount the fan’s digital, variable-speed wall controller to a standard junction box with a Cat5 cable and you’re up and running. A resistive-touchscreen makes it easy to turn your fan on or off, change speed, and set password protection.
Need something with greater functionality than our standard digital controller? We offer several upgrades to provide comfort, energy savings, and security for your people and property.
