The present system is an adsorption system (100) for separating air into a concentrated gas component, which has an air supply, a compressor (115) for receiving and compressing the air supply, providing a compressed air supply, and molecular sieve material for separating the compressed air supply into a concentrated gas component. The adsorption system delivers at least 5 liters per minute (LPM) of concentrated gas component from the molecular sieve material in which the system has a specific total weight per LPM9 lbs/LPM. Additionally, an output quantity of the concentrated gas is delivered by the adsorption system and a purging quantity of the concentrated gas is dispensed into a sieve chamber of the adsorption system undergoing a purge cycle. The purging quantity has a value equal to or less than the difference between the maximum quantity and the output quantity, and the purging quantity is controlled based on the output quantity.
