PURPOSE:To provide an oxygen amplified air supplying device capable of obtaining oxygen amplified air, having a high containing rate of oxygen, from air by a method wherein an oxygen amplifier having an oxygen amplifying film constituted by forming a high-polymerized thin film on a porous supporting film, a fan, taking air from a suction port and sending it by a pressure to the oxygen amplifier, and a suction pump, sucking and filtrating the air sent by pressure to the oxygen amplifier through an oxygen amplifying film, are utilized. CONSTITUTION:The oxygen amplifier 12 is formed by bundling the oxygen amplifying film 10, employing hollow thread-like porous glass as the supporting film. The oxygen amplifying film 10 is opened at the both ends thereof and is held in a sealed condition in the flow path of the air in the vessel 19 by employing seal members 22A, 22B. Air is taken from a suction port 14 by driving the fan 16 and is sent by the pressure into the oxygen amplifier 12 while the air is sucked and filtrated through the oxygen amplifying film 10 by driving the suction pump 18 and, thus, the oxygen-rich air is supplied from a blow off port 20. Gas, except said air, such as nitrogen, carbon mono-oxide, carbon dioxide or the like, for example, are discharged out of a discharging port 24. |
