ST Engineering receives AML-STC for the installation of Aviation Clean Air’s Proactive Air Purification Solution

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

With the certification, the company can install the patented ‘Needlepoint Bipolar Ionisation System’ (NPBI) that neutralises pathogens and purifies air in cabin interiors during flight operations on commercial and VIP-configured Airbus A320/A321 aircraft.

ST Engineering’s vice president and head of cabin interior and engineering solutions Tan Yen Ping said: “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.”

ACA’s air ionisation and purification system is powered by the patented NPBI process, which the company said “has been problem 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 per cent of airborne and surface pathogens, including the SARS-CoV-2 virus, the company added.
