Powerfoil 8’s purpose-built motor and patented airfoil system move up to 245,000 cubic feet of air per minute (116 cubic meters per second). The airfoils’ aerodynamic design, cuffed winglets, and AirFences™ reduce wind turbulence and noise, keeping airflow consistent throughout the coverage area.
4/5
A single 24-foot (7.3-meter) Powerfoil 8 can effectively deliver air speeds of at least 85 feet per minute (0.43 meters per second) to occupant levels over an area of more than 28,500 square feet (2,650 square meters). The fan’s range of diameters and variety of mounting options, combined with Big Ass Fans’ proprietary application design tools and expertise, ensure ideal airflow coverage for virtually any space.
5/5
Powerfoil 8’s 0.75-1.5 kilowatt motor efficiently delivers cooling airflow over a wide area, lowering the need for A/C. In winter, the fan equalizes temperatures from floor to ceiling, making heaters more efficient. This improvement in efficiency can reduce HVAC costs by up to 30%, which more than offsets the fan’s modest estimated annual operational cost of US$307—about $0.84 per day.
5/5
Powerfoil 8’s standard digital touchscreen controller allows users to turn fans on and off and adjust speed from an easy-to-use interface. Rated IP55 for the toughest environments and easy to install, the controller features durable housing, a wall bracket, and a single RJ45 port.
5/5
Powerfoil 8 measures quieter than most ambient processes in industrial applications, which typically measure 40-60 dBA. When run at low speeds for destratification, the fan’s operational sound is imperceptible at occupant level. |

5/5
Like all Big Ass industrial overhead fans, Powerfoil 8 features airfoil and hub systems made from extruded aluminum, which offers greater flexibility and protection from impacts than cast aluminum. Its heat-resistant construction and wide range of protection for voltage sag/swell make the fan an excellent choice for industrial facilities that lack A/C and experience fluctuations in power quality.
4/5
Powerfoil 8 features a non-prorated 7-year mechanical and 3-year electrical warranty. Big Ass Fans’ warranties are noteworthy for their straightforward terms and factory-direct service. Warranty terms vary by region. See bigassfans.com/product-warranties/ for full details.
5/5
Powerfoil 8 has undergone extensive third-party testing by the U.S. Department of Energy to guarantee accurate performance claims and adhere to industry regulations and standards.
5/5
Powerfoil 8 features a vented motor with double lip seals, helical gears, and ball bearings that reduce friction and protect against dust, grit, and water for smooth, long-lasting performance. As with all our overhead fans, Big Ass Fans offers a preventive maintenance program to ensure your Powerfoil 8 maintains peak performance and efficiency.
5/5
Powerfoil 8 is rated IP56, making it thoroughly protected from dust and particles and fully safeguarded against vapors and sprays of water, and its digital touchscreen controller is rated an industry-leading IP55. |

5/5
Powerfoil 8 includes a mounting system with dual galvanized steel aircraft cables designed to support the full weight of the fan, an extruded aluminum spar hub system, and Grade 8 hardware to secure components. Every weld has redundant means of safety, so no single weld is critical to the fan’s security.
5/5
Powerfoil 8 ensures maximum operational safety with dynamic features that keep all fan parts secured to the assembly in the event of an impact. Each airfoil sports interlocking retainers and a full-length airfoil restraint system, while the 19-inch (483-millimeter) spar hub system features two flexible plates with an aluminum spacer, ¼-inch (6.35-millimeter) steel retainers, and pin and collar rivet fasteners to more evenly distribute force load and reduce fatigue at attachment points. As with all Big Ass overhead fans, Powerfoil 8 integrates with fire suppression systems.
5/5
Powerfoil 8’s safety is proven through rigorous testing. The fan holds an international CB Test Certificate for passing CB Scheme safety certification and is ETL-listed to UL507 and CSA Standard 22.2 No. 113. At Big Ass Fans’ research lab, the fan has undergone successful impact testing, mount tensile testing to 28,000 pounds-force (12,700 kilograms-force), and stress testing of hub and airfoil systems, the results of which far surpass competitor testing in scope and performance.
5/5
Like other Big Ass overhead fans, Powerfoil 8 integrates with most third-party building automation systems, offering fan control, grouping, and fire relay integration using Modbus-RTU protocol, 0-10 VDC, and optional BACnet capability.
5/5
Featuring 23 patents for its airfoil and safety systems as well as patents pending for its mount and hub systems, Powerfoil 8 holds an impressive track record of airflow innovation. The fan’s purpose-built design demonstrates Big Ass Fans’ commitment to engineering safe, effective products that provide comfort and cost savings. |
