The system is an adsorption system (100) for separating air into concentrated gas components, an air source, a compressor (115) that receives and compresses the air source and supplies a compressed air source, and the compression It has a molecular sieve material for separating the air source into concentrated gas components. The adsorption system supplies a concentrated gas component at least 5 liters per minute (LPM) from the molecular sieve material. The system has a specific total weight per LPM of 9 pounds / LPM. Further, the output amount of the concentrated gas is supplied by the adsorption system, and the purge amount of the concentrated gas is injected into the sieve chamber of the adsorption system that undergoes a purge cycle. The purge amount has a value that is less than or equal to the difference between the maximum amount and the output amount, and the purge amount is controlled based on the output amount. |
