Estimating the term…
The present invention provides, as a pressure swing adsorption type oxygen concentrator aiming to be used for the home oxygen therapy, and having the device reliability ensuring a low failure occurrence rate, and the adsorption performance stability, ensuring the stable oxygen concentration performance even over a long period, a pressure swing type oxygen concentrator having at least one adsorption column charged with an adsorbent capable of preferentially adsorbing nitrogen rather than oxygen, and an air compressor for pressure supplying and/or vacuum exhausting air to and/or from the adsorption column, characterized by including a nonwoven fabric filter for collecting sealing material wear particles in an air channel between the adsorption column and the air compressor.
