Duncan Aviation recently obtained supplemental type certificate (STC) approvals from Transport Canada Civil Aviation and EASA for an installation package for the Aviation Clean Air (ACA) ionization system aboard Bombardier Globals and Challenger 300/350s.

The approvals clear the way for Duncan customers in Canada and the European Union to buy the ACA packages for their aircraft, including the STCs, ionizers, and PMA parts kits. “We’re seeing strong demand for the ACA system in Europe and the Middle East,” said avionics installation sales rep Steve Elofson. “A Global Express in Europe is currently having the ACA Ionization system installed in accordance with the EASA-approved STC.”

Designed for installation in the aircraft’s existing environmental control system, the ACA ionizers neutralize pathogens, including those that cause the flu and the common cold, and removes allergens and unpleasant odors. Testing from independent lab Innovative BioAnalysis found that the ACA ionizer was effective at rendering the Covid-19 coronavirus harmless, Duncan said, noting that 99.4 percent of the virus particles were inactivated within 30 minutes.

Most of Duncan’s main facilities and satellite shops are able to perform necessary modifications before installing the ACA Ionizer system.
