High Temperature Membrane for OBIGGS Application
Honeywell’s Innovative High Temperature Membrane
Oxygen and water vapor are “fast” gases which quickly permeate the membrane, allowing nitrogen to flow through the fiber bores as the product stream.
This illustration shows how fast gases like oxygen and moisture permeate the surface of the individual membrane fibers while nitrogen molecules remain inside and are delivered as the product gas.

Thousands of individual fibers wrapped around a core make up the nitrogen generating hollow fiber membrane module. The engineering of the module is important to maximizing the performance of the whole system.
