<p><P>PROBLEM TO BE SOLVED: To provide a pressure-fluctuation adsorption type oxygen concentrator carrying a dehumidifier which can efficiently remove moisture in raw material air. <P>SOLUTION: The pressure-fluctuation adsorption type oxygen concentrator 1 comprises an adsorption floor filled up with an adsorbent which alternatively adsorbs nitrogen rather than oxygen, an air supply means 120 which provides pressurized air, a raw material, to the adsorption floor and suction removes the exhaust from the adsorption floor, and an oxygen feed means which feeds to a user oxygen enriched air formed from the adsorption floor, and comprises a moisture separating means including a moisture-permeable membrane 131 which separates moisture in air and in which the primary side of the moisture-permeable membrane 131 is connected to a pipe which feeds the pressurized air between the air supply means 120 and the adsorption floor and the secondary side of the moisture-permeable membrane 131 is connected to the pipes for evacuation of the adsorption floor and the air supply means 120. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
