The air separation module (ASM) uses semi-permeable, hollow fiber membranes, packaged in a cylindrical canister that removes oxygen from a compressed air stream to generate a nitrogen enriched air (NEA) stream. Parker Aerospace's air separation modules are used in a variety of our inerting systems designed and manufactured for military, commercial, and business aircraft.
Our separation modules benefit from proprietary, higher-performance Parker fibers not available to other companies, resulting in a smaller, lighter, and less-costly system.
Parker's air separation module (ASM) keeps fuel tanks more safe, utilizing our semi-permeable hollow fiber membrane technology. The Parker fiber also has the highest performance of all available aerospace ASMs, enabling the smallest total ASM weight and package volume on the market today.
Each ASM is put through rigorous test scenarios to meet strict requirements for tolerance and resistance. Parker has broad experience in analyzing, testing, and fielding all major ASM fibers, allowing the best choice of fiber to be selected for each program or application.
As the premier world leader in fuel tank inerting systems, Parker has turned 50-plus years of inerting technology leadership into an unequalled pedigree that translates into durable, world-class products that last, flight after flight.
