Whether it’s large distribution centers, smaller manufacturing plants, schools, healthcare centers or a variety of commercial spaces, wherever people are gathered, you’ll find harmful pathogens that can cause diseases like COVID-19 and influenza. Big Ass Fans® Clean Air System is designed to destroy those pathogens, providing safer, cleaner air that everyone can enjoy.

A one-of-a-kind solution, Clean Air System delivers unmatched airflow, efficiency, and air disinfection to transform your facility’s health and comfort.

CREATING CLEANER AIR DRAMATICALLY REDUCES INFECTION RISK

The Big Ass Fans' Clean Air System pairs scientifically proven air purifying technologies with powerful airflow solutions. This results in a system that kills 99.99% of pathogens to keep your people protected and your business booming.

ION DISINFECTION TECHNOLOGY
Industrial / Commercial

Ions are electrically charged particles that are proven to attack and eliminate pathogens. Big Ass Fans – armed with bipolar ionization units – create millions of ions per minute and distribute them rapidly through powerful airflow. This provides cleaner, safer air and surfaces – all without producing any harmful ozone.

UVGI (UV-C) DISINFECTION TECHNOLOGY
Commercial / Residential

UV-C light has been a scientifically proven disinfectant for over 70 years. By incorporating CDC endorsed UVGI (UV-C) technology with Big Ass Fans, pathogens move through an upper-air-level disinfection zone – continuously and safely providing clean air where it’s needed most.

REDUCING RISK WITH EVERY SPIN

Big Ass Fans’ full-service air disinfection solution kills 99.99% of SARS-CoV-2 (the virus that causes COVID-19) and other airborne pathogens throughout your space.

How does Big Ass Fans' Clean Air System work? add

Big Ass Fans’ innovative Clean Air System is a full-service, facility-wide air quality solution that kills airborne pathogens in your space. Big Ass Fans’ Clean Air System operates under three key features:

Powerful Airflow – Why bother disinfecting the air if it never actually reaches your people? Their fans’ superior airflow is the key to delivering clean, comfortable air to the spaces where we live, work, and breathe.

Proven Technology – Air disinfection methods have existed for decades, but seamless integration into their industry-leading products makes this technology more practical and more effective than ever before.

Unmatched Expertise – They’re the airflow experts. With our custom specification, commercial/industrial installation, and a lifetime of system support and maintenance, you’ll keep your people protected for the long haul.

Which Big Ass Fans products are currently part of the Clean Air System? add

Big Ass Fans offers the following products with Clean Air System:

For industrial and commercial applications:

  • Powerfoil X3.0 (12 – 24 feet diameter)
  • Powerfoil D (8 – 24 feet diameter)
  • AirEye (20 – 30 inch diameter)

For commercial and residential applications:

  • Haiku (52, 60, and 84 inch diameter)
  • Essence (8-14 feet diameter)

Where do I use "UVGI (UV-C)” technology versus “ionization” technology? add

Both technologies have their relevant advantages, depending on application, which is why Big Ass Fans has implemented both into specific products.

FOR SMALLER SPACES (EX. RESIDENTIAL, COMMERCIAL, AND OFFICE SETTINGS):

Speaking to Haiku with UV-C technology, UV-C has over one hundred years of proven performance and is recommended for pathogen inactivation by ASHRAE, the Centers for Disease Control, the World Health Organization, and the Illuminating Engineering Society. Haiku with UV-C technology works best in applications where there is a ceiling covering the space, particularly in residential and commercial office settings.

FOR LARGER SPACES (EX. COMMERCIAL, INDUSTRIAL AND WAREHOUSE SETTINGS):

Combining ion and UV-C technologies with the airflow management and power of a Big Ass fan will dramatically affect the efficiency of the solution.
