For 20 years, Big Ass industrial fans have set the standard for powerful, efficient airflow that transforms uncomfortable facilities and lowers overhead costs. They’re pacing the field with Powerfoil D, the only direct-drive overhead fan purpose-built for harsh industrial conditions.
Big Ass Fans was forged in industrial conditions, so they 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:
- 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 shutdown upon impact
- Fire suppression system integration for automated safety
Powerfoil D’s 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.

Air ions are formed when a molecule gains enough energy to become ionized. In nature, sources of energy that can cause this to occur include background radiation, ultraviolet light, cosmic radiation, atomization of water, movement of large masses of air, and lightning. Normal, fair-weather air ion concentrations range from 200 to 800 negative and 250 to 1500 positive ions/cm3. An approaching storm can increase the positive air ion concentration to over 5,000 ions/cm3! (source)
Air ions are charged molecules that are naturally found in the air. In addition to their natural occurrence, air ions can also be generated artificially through ion technology generators or as byproducts of other industrial processes. Both positive and negative ions are formed when molecules or atoms lose or gain electrons. Common ions found in the air include H+, H3O+, O+, N+, CO4-, OH-, H2O-, and O2-.
Big Ass Fans’ Clean Air System ionization systems produce positively and negatively charged ions that attach to the surface of the cell membrane of airborne pathogens. The organism’s membrane is degraded, leaving genetic material exposed to oxidation, resulting in pathogen inactivation.
A jet of airflow is created by the Big Ass fan, which runs across the Clean Air System ionizers and increases the overall rate of ion generation in a space. If you can feel the breeze generated by our fans, then you are in an area of increased ion concentration.
The half-life of an air ion is dependent on its size and mobility. Negative ions tend to be smaller with half-lives of several minutes in dry, clean outdoor air while positive ions are larger and have half-lives of about 30 minutes. When indoors, the life of an ion is much shorter because of the increased probability of the ion shorting to ground by contacting a wall or surface. Therefore, in a confined space ions may only “live” for about 30 seconds. (source)
Both technologies have advantages and disadvantages, depending on the application. Ionization systems do not rely on recirculation of air to be effective, so semi-outdoor applications are a much better match for ionization systems. Ionization systems also offer the added benefit of surface cleaning, which may be critical in some applications.
Yes, retrofits are available for Big Ass Fans’ ion technology products.
No. The Big Ass Fans’ Clean Air System ionizer will operate once powered, and in sync with the Big Ass fan, when the fan is in continuous operation.
Yes. Air ions are naturally occurring and form when a molecule gains enough energy to become ionized. Testing proves that high concentrations of strategically-placed ions, like those produced in Big Ass Fans Clean Air System ion products, will deactivate airborne pathogens in your space and create a safer environment for everyone occupying it.
ASHRAE Standard 62.1-2019 Section 5.7.1 mandates that all air-cleaning ionization systems be listed and labeled to UL 2998, which provides certification that the air cleaning product has zero ozone emissions. Big Ass Fans’ Clean Air Systems ionization technology is listed and labeled to UL 2998 standard, certifying the products as ozone-free.
The Big Ass Fans’ Clean Air System ionization unit is powered, and injury may result if the unit is touched while in operation. For directional fans, the ionization unit is placed behind our engineered caging. For overhead fans, the unit is placed on the fan which is out of reach of immediate personnel.
No. The Big Ass Fans’ Clean Air System ionizer will operate at any point when your Big Ass Fan is receiving power.
Yes. The Clean Air System ionizer will run continuously with your normal use of your Big Ass fan.
A green LED indicator light will illuminate when power is applied to the unit and ions are being generated.
Your Big Ass Fans certified installers will complete 3 annual calibrations following the initial installation. This process will consist of:
- Visiting the customer’s site annually, for 3 years, after the initial installation and commissioning of the Big Ass Fans’ Clean Air System
- Inspection and cleaning of the customer’s Clean Air System
- Testing to verify Clean Air System ion operation and levels, followed with a post-test report
