ST Engineering receives AML-STC for installation of ACA’s air purification solution

ST Engineering has announced that the Commercial Aerospace business of ST Engineering 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.

With the certification, ST Engineering can 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.

Howard Hackney, ACA managing member added: “ST Engineering is well-known and respected for its innovation and engineering capabilities. Their proven MRO expertise in serving airlines worldwide enhances ACA’s distribution network and allows more operators to experience the benefits of our system.”

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. Compared to solutions that only sanitise a cabin interior after a flight, ACA’s solution provides passengers with continuous and more proactive protection.
