PROBLEM TO BE SOLVED: To provide an oxygen concentrator for lowering noises.
SOLUTION: The oxygen concentrator of a pressure swing absorption type has: an absorption cylinder for filling up an absorption material for absorbing nitrogen in favor of oxygen an air compressing means for supplying the absorption cylinder with compressed air and a flow path switch valve for repeating an absorption process for pressuring the absorption cylinder, absorbing nitrogen in the compressed air, and generating oxygen unabsorbed and a process of attachment/removal for reducing pressure in the absorption cylinder to regenerate the absorption material with regular timing. When two or more flow path switch valves simultaneously operate, timing at which the respective flow path switch valves switch has a minute time deviation.
