WITH INDUSTRIAL FANS, SAFETY IS ALWAYS FIRST

Here at Big Ass Fans , we live and breathe industrial conditions, so we know 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.

Durable Grade 8 hardware and no critical exposed welds for fail-safe connections
Two-set safety cable system made from aircraft-grade galvanized steel
Steel retainers and Airfoil Restraint System for robust hub and airfoil security
Built-in accelerometer for automatic fan shutdown upon impact or if a shift in building structure is detected
Fire suppression system integration for automated safety

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–because industrial safety is always the first priority.

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, durable operation.
