<p>Disclosed is an oxygen concentrator which can supply stable feed air to an absorption unit immediately after start-up, even when started-up at low rotation. The oxygen concentrator is provided with a compressed air generator, which has an inbuilt rotation body and generates compressed air, and a suction unit, which introduces the aforementioned compressed air to an inner section and, by means of an adsorbent filled into said inner section, absorbs nitrogen and separates and produces oxygen. The aforementioned compressed air generator has a control unit (200) which controls the rotational frequency of the aforementioned rotation body such that the rotational frequency is appropriate with regard to the amount of oxygen being generated. When the device starts up, said control unit drives the rotational frequency of the aforementioned rotation body at a higher rotational frequency than that previously determined.</p> |
