Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an oxygen concentrator for safely treating high concentration oxygen stored in a tank.SOLUTION: The oxygen concentrator includes: ducts 101A, 101B for returning high concentration oxygen stored in a product tank 41 to sieve beds 33A, 33B; and discharge valves 102A, 102B for closing the ducts 101A, 101B when the oxygen concentrator 1 is used and opening the ducts 101A, 101B when the oxygen concentrator 1 is not used. Thus, when the oxygen concentrator 1 is not used, the high concentration oxygen stored in the product tank 41 is mixed with nitrogen inside the sieve beds 33A, 33B, so that the oxygen concentration is reduced. Consequently, the high concentration oxygen stored in the product tank 41 is safely treated.
