Duncan Aviation is offering the installation of a chemical-free air purification system at its three main facilities and satellite shops. The MRO provider has installed the system in a Gulfstream and is working on approvals for other aircraft.

The purifier, from Aviation Clean Air (ACA), is an active air-filtration system installed in an aircraft’s environmental control system to improve cabin air quality, killing pathogens and removing odors allergens, Duncan said. Components are housed in a black anodized aluminum box and weigh 1.34 pounds.

“Because it’s not a static air filter, the system actively kills viral, bacterial, and fungal pathogens, such as those that cause the common cold, flu, MRSA (methicillin-resistant staphylococcus aureus), C. diff (clostridium difficile), E. coli (escherichia coli), pneumonia, polio, and mold,” the MRO provider said. In addition, it neutralizes gases resulting from fuel emissions and other volatile organic compounds, and odors caused by cooking, cleaning, cigarette smoke, stagnant air, pets, and lavatories.

ACA developed an ionization process that prevents the ability of pathogens to bond, said Duncan Aviation’s senior avionics sales rep Steve Elofson. “The ACA component, in a process involving cold plasma, causes a chemical reaction that changes the positive and negative ions, severing hydrogen bonds on the cell’s surface. Without these bonds, the pathogen will not be able to mutate or reproduce and will quickly die.”
