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.

Powerfoil LED

Powerfoil D’s ultra-bright and fully dimmable LED upgrade outshines the competition and makes a visible difference in any environment. It’s no secret that workers in well-lit facilities are safer, happier, and more productive.

Industrial Power, Quiet, and Comfort

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. In winter it optimizes energy efficiency and comfort by gently recirculating the heated air trapped at the ceiling back down to people at the ground floor.

Versatile and Customizable Industrial Fan

We purpose-built Powerfoil D for industrial spaces, but its feature-rich design is a great match 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.
Other Optional Features:

  • BACnet adapter
  • Mounting kits for solid beams and purlins
  • Extended warranty
  • Advanced controller options

Touchscreen Simplicity

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.
