<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for generating low-concentration oxygen, the manufacturing cost and running cost of which are reduced. <P>SOLUTION: An air intake 1a to which air is supplied via a solenoid valve 2 by a compressor 3 and a sampling port 1b for sampling the low-concentration oxygen generated in a vessel 1 via a solenoid valve 4 are arranged at one end of the vessel 1 packed with zeolite. A discharge port 1c for temporarily discharging the high-concentration oxygen generated in the vessel 1 via a solenoid valve 6 is arranged at the other end of the vessel. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
