Aviation Clean Air (ACA) offers a proven solution to decontaminate aircraft interiors The patented NPBI™ Ionization technology that powers the Aviation Clean Air (ACA) Airborne Unit and the Ground Unit immediately: -Neutralizes Surface and Airborne Viruses, including COVID-19 -Sterilizes Mold and Bacteria and Removes Odors -Improves Air Quality -Produces no Ozone -Neutralizes Common Industrial Gases -Reduces Static Electricity ACA’s patented Airborne Unit, which is certified for aircraft installation by FAA Supplemental Type Certification (STC), provides constant decontamination of the aircraft interior, keeping passengers and crew protected throughout the flight. The proactive system operates through the aircraft’s existing environmental control system (ECS), and immediately kills pathogens in the air and on surfaces. ACA has Parts Manufacturer Approval (PMA) for the system and is an Approved Supplier to several OEM aircraft manufacturers. ACA holds the Patent for Design and Utility: for the Aircraft Proactive Air and Surface Purification Component from the U.S. Patent Office. In March 2020, ACA partnered with International Aero Engineering (IAE) to offer its Ionization Purification System as a Portable Ground Unit. The unit utilizes the same tested, proven technology as ACA’s patented airborne system to effectively clean and purify aircraft interiors while on the ground. The electric-powered ionization and air blower unit (110V or 220V) decontaminates the interior in one to two hours, depending on aircraft size. Well over a thousand Ground Units and Airborne Systems, utilized by a wide variety of aircraft platforms and operations, have been delivered.
