Duncan Aviation STC for ACA air purification in Global slated for July

Duncan Aviation is anticipating the completion and availability of its first supplemental type certificate (STC) for the Aviation Clean Air (ACA) ionisation system for a Global aircraft on July 24. The Duncan Aviation engineering and certication services team is developing the STC to cover the installation of the safe and effective air ionisation system, and the team is also working on paths to certify other makes/models, including a Challenger 300/350.

Designed to be installed in an aircraft's existing environmental control system, ACA is an air- and surface-purification system. The ACA system improves air quality throughout the aircraft and, more importantly, kills pathogens and removes allergens and unpleasant odours.

In May, lab testing conducted by independent lab Innovative BioAnalysis found the ACA ioniser effective at rendering harmless the novel coronavirus that causes COVID-19. The lab test showed that 99.4% of the virus particles were inactivated within 30 minutes.The system has been tested and proven to kill the coronavirus that caused SARS (Severe Acute Respiratory Syndrome), as well.

The ionised hydrogen molecules also deactivate other viral, bacterial and fungal pathogens such as those that cause the common cold, flu (swine, avian, etc.), MRSA (methicillin-resistant Staphylococcus aureus), C. diff (clostridium difficile), E. coli (Escherichia coli), pneumonia, polio and mold.

In addition to pathogens, the ACA component neutralises potentially harmful gasses caused by fuel emissions, other VOCs (volatile organic compounds) and offensive odours caused by cooking or cleaning, cigarette and cigar smoke, stagnant air and lavatories. Pet odours are also neutralised. The system will also reduce the static electricity in aircraft that is caused by the low relative humidity of the cabin air.

"Like our customers, we have always known there were dangerous viruses and bacteria in the world. We've all heard of the SARS and MERS viruses and drug-resistant bacteria, and now we can add COVID-19 to the list. Avoiding them mostly meant washing our hands often and thoroughly," says Michael Kussatz, avoinics regional sales in the Eastern US. "After doing some research, we found that the ACA ionisation system gives pilots and passengers a space where there is a very natural process going on that is deactivating these pathogens, rendering them harmless, as we travel in comfort.”

Because installation can typically be completed in less than two weeks, Duncan Aviation can install the ACA air ioniser as a stand-alone event or part of a scheduled-maintenance event.
