Abstract
A method of monitoring health of an oxygen concentrator assembly within an onboard oxygen generating system (OBOGS) operable to produce an oxygen enriched gas is provided. The OBOGS includes a controller, a plurality of molecular sieve beds for producing the oxygen enriched gas, and a mechanical system for selectively communicating an inlet air to a subset of the plurality of molecular sieve at a given time. The method includes monitoring the health of the overall OBOGS and the mechanical system to determine whether one or more of the molecular sieve beds and/or the oxygen concentrator assembly need to be serviced.
