The Air Separation Module (ASM), is a key fuel tank inerting system component which protects fuel tanks from ozone combustion. However, ozone is a powerful oxidant that can degrade materials commonly used in fuel tank inerting systems causing it to fail.

This white paper, written by Abdullah Alyafawi, Ph.D, an Eaton R&D Engineer, will outline the challenges ozone presents to ASMs, and the multiple layers of protection that were designed to produce an ASM that exceeds all ozone protection reliability tests, ensuring longer life on-wing and greater performance. For more than 40 years, Eaton has been advancing fuel tank inerting technology.
