<p>PROBLEM TO BE SOLVED: To provide an oxygen enricher of which the air suction noise and the nitrogen exhaust noise are decreased as much as possible. SOLUTION: When the compressed air from an air compressor is supplied into a nitrogen adsorbing chamber composed to adsorb nitrogen selectively, a gas in which oxygen is highly enriched is produced. A silencer is set up at the outlet of the pipe to exhaust the adsorbed nitrogen in the nitrogen adsorbing chamber. A pipe of which the inside diameter is larger than that of the suction pipe of the air compressor is installed at the air suction pipe. A pipe of which the inside diameter is larger than that of the connecting pipe between the silencer and the nitrogen adsorbing chamber is installed at the connecting pipe.</p> |
