<p><P>PROBLEM TO BE SOLVED: To provide a silent oxygen concentrator elongating the service life of a compressor by lowering an intake-air temperature of the compressor without lowering the product oxygen concentration, and reducing the intake-air noise. <P>SOLUTION: This oxygen concentrator is provided with: at least an adsorption column filled with adsorbent preferentially adsorbing nitrogen to oxygen; an air compression means for supplying compressed air to the adsorption column; a cooling means for cooling the air compression means; and a sound insulation box for reducing radiated noise of the air compression means, wherein the sound insulation box is divided into two chambers by a partition wall and has two flow paths where a cooling air flow path for supplying the cooling air to a first chamber and a raw material air flow path for supplying raw material air to the air compression means are divided by a partition respectively, and the second chamber is provided with the air compression means. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
