ACA’s air ionisation and purification system is powered by the patented NPBI process, which has been proven to swiftly purify the air and surfaces as well as neutralise viruses and bacteria throughout an aircraft interior.

ST Engineering’s commercial aerospace business has received the Approved Model List Supplemental Type Certificate (AML-STC) from the Federal Aviation Administration (FAA) to install Aviation Clean Air (ACA)’s cabin air purification solution on Airbus platforms.

The certification allows ST Engineering to install the patented Needlepoint Bipolar Ionisation (NPBI) System that neutralises pathogens and purifies air in cabin interiors during flight operations on commercial and VIP-configured Airbus A320/A321 aircraft.

“With more borders opening up, we want to help boost passenger safety and confidence, and enhance passenger comfort with innovative cabin interior sanitisation solutions. By combining our MRO and engineering expertise with ACA’s patented purification system, we aim to provide this proven and low-maintenance solution to support the return to flying,” said Tan Yen Ping, Vice President and Head, Cabin Interior and Engineering Solutions, ST Engineering.

ACA’s air ionisation and purification system is powered by the patented NPBI process, which has been proven to swiftly purify the air and surfaces as well as neutralise viruses and bacteria throughout an aircraft interior. The system is able to stop the spread of up to 99.9% of airborne and surface pathogens, including the SARS-CoV-2 virus. The NPBI process can also remove odours, dust and pollen; prevent mould, neutralise common industrial gases and reduce static electricity.

The system is automatically activated during flights to provide constant decontamination of the aircraft interior without using or introducing chemicals.

Duncan Aviation's ACA ionisation system

Duncan Aviation’s Engineering & Certification Services and Parts Manufacturer Approval (PMA) departments have created an installation package for the Aviation Clean Air (ACA) ionisation system for Challenger 300 and 350 aircraft.

The packages include everything necessary for installing the ACA Ioniser system, including the Supplemental Type Certificate (STC), the ionisers, and PMA parts kits.

“Although our facility in Lincoln, Nebraska, has been modifying the air ducts for the installation, any of Duncan Aviation’s three main facilities or many of the company’s 27 Satellite Shops, are able to perform the necessary modifications prior to installing the ACA Ioniser system,” commented Pat Mapes, Manager of Avionics Install & Avionics Line. “When we say the kit includes everything, we mean every screw, nut, bolt, and switch necessary for the installation.”

The teams have also created ACA Ionisation installation packages for the Global models. Kits are currently available for those aircraft and can also be installed at any of the three main Duncan Aviation facilities or Satellite Shops. Additional STCs and PMA kits are in work for the Falcon 2000 and 7X models and should be available in the coming months.

Designed to be installed in an aircraft’s existing environmental control system, the ACA ionisers operate in the aircraft’s ductwork. The ionised hydrogen molecules neutralise pathogens and remove allergens and unpleasant odours, including those from pets, cigarette and cigar smoke, engine exhaust, cooking, lavatories, and VOCs (volatile organic compounds).

In May 2020, 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.

Satair to distribute Ionisation Purification System

Satair is to distribute Aviation Clean Air (ACA) Air Ionisation and Purification System.

The patented ACA airborne deactivates airborne pathogens, viruses and bacteria while congruently reducing Volatile Organic Compounds (VOCs) and odours.

Matt Jessee, Head of Business Development, Global Distribution, Satair says: “This product has been utilised in VIP and military operation for years, and now will be made available to all airline customers via Satair.”

The system uses needlepoint bipolar ionisation (NPBI) technology. It works by leveraging an electronic charge to create a high concentration of positive and negative ions. These ions travel through the air continuously seeking out and attaching to particles, setting in motion a continuous pattern of particle combination. As these particles become larger, they are eliminated from the air with increased speed. Additionally, positive and negative ions have microbicidal effects on pathogens, ultimately reducing the infectivity abilities of viruses and bacterial pathogens.

Howard Hackney, Managing Director of Aviation Clean Air, commented, “Test results have proven that our needlepoint bipolar ionisation concept neutralises many pathogens, including SARS-CoV-2 without representing any health risks, as this technology does not create ozone.”

In tests jointly conducted with Aviation Clean Air, Global Plasma Solutions has demonstrated the effectiveness of its proprietary needlepoint bipolar ionisation technology to neutralise SARS-CoV-2 (COVID-19) on surfaces.

In tests jointly conducted with Aviation Clean Air, Global Plasma Solutions has demonstrated the effectiveness of its proprietary needlepoint bipolar ionisation technology to neutralise SARS-CoV-2 (COVID-19) on surfaces.

In the laboratory study, Aviation Clean Air designed a test to mimic ionisation conditions such as those of a commercial aircraft’s fuselage. Based on viral titrations, it was determined that at 10 minutes, 84.2% of the virus was inactivated. At 15 minutes, 92.6% of the virus was inactivated, and at 30 minutes, 99.4% of the virus was inactivated.

Needlepoint bipolar ionisation leverages an electronic charge to create a high concentration of positive and negative ions. These ions travel through the air continuously seeking out and attaching to particles. This sets in motion a continuous pattern of particle combination. As these particles become larger, they are eliminated from the air more rapidly.

Additionally, positive, and negative ions have microbicidal effects on pathogens, ultimately reducing the infectivity of the virus. Global Plasma Solutions’ needlepoint bipolar ionisation is ozone-free and the only kind in its category to pass the RCTA DO-160 standard for aircraft.

Traditional bipolar ionisation systems produce harmful ozone as a byproduct.
