Oxygen concentration system

An adsorption system (100) for separating air into a concentrated gas component, the system comprising:

• a compressor (115) for receiving and compressing air from an air supply, providing a compressed air supply;
• molecular sieve material for separating the compressed air supply into a concentrated gas component;
• a first molecular sieve chamber (130) for receiving the molecular sieve material;
• at second molecular sieve chamber (135) for receiving the molecular sieve material;
• a supply chamber for receiving the compressed air supply and for communicating the compressed air supply to the first and the second molecular sieve chambers;
• an outlet delivering a concentrated gas component from the molecular sieve material;
• and
• a fixed orifice for communicating the concentrated gas component between the first molecular sieve chamber and the second molecular sieve chamber,
• wherein the molecular sieve material has a total molecular sieve material weight, and wherein the total molecular sieve material weight per square inch of the area of the fixed orifice is less than <3,000 lbs/square inch.
