Donaldson Expands Air Purification System Offerings to Airbus A330/A340

Sept. 15, 2020

Donaldson Aerospace & Defense, a division of the Donaldson Company, Inc. has received product manufacturing approval for its A330/A340 Air Purification System (APS).

Originally developed in conjunction with Boeing for the 787 Dreamliner, Donaldson’s innovative APS pairs EASA-recommended HEPA filtration with advanced air purification into a single system.

Donaldson’s HEPA filtration captures 99.97 percent of harmful contaminants down to 0.3 microns, including pollen, smoke, dust, allergens, bacteria, spores, fungus and viruses. Air purification takes HEPA’s work one step further by removing odors as well. Air purification is achieved through a gas phase adsorption chemical filtration process that removes unpleasant and irritating odors originating inside and outside the aircraft that inhibit passenger comfort – exhaust, anti-icing fluid, bleed air, perfume, cleaning agents, harsh chemicals, etc. The result is cleaner air to breathe for all onboard for a more comfortable environment.

“The Donaldson APS gives airlines the peace of mind that they are going the extra mile to ease passenger comfort,” said Fixed Wing Director, Lars Hesbjerg. “Commercial airline passengers want to breathe air that is clean and free of allergens, uncomfortable odors and potentially harmful particulates. With the extensive cleaning airlines are undertaking today with harsh chemicals that can affect allergies, the Donaldson APS helps ensure fresh, clean air to increase passenger comfort.”

The Donaldson APS is interchangeable with the HEPA filter with minimal weight increase and similar change intervals compared to a standard particulate filter.

Donaldson’s APS is currently installed and in use on hundreds of Airbus A320s and Boeing 777s, and all Boeing 787 Dreamliners. Approval for the Boeing 777 is expected later this year.
