SELECTIVE GAS ENRICHING DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent air amount permeated through a gas enriching membrane from being reduced by controlling the temperature of a gas enriching unit in a selective gas enriching device. SOLUTION: This selective gas enriching device comprises a gas enriching unit 31 having a function for increasing the concentration of specified gas components, a temperature control means 52 for controlling the temperature of the gas enriching unit, a pump 32 feeding out the gas components, and an outlet port 33 for discharging the gas components fed out from the pump 32.
