PURPOSE:To provide the titled module capable of obtg. oxygenenriched air from air with small pressure drop by housing assemblies of hollow yarn comprised of hollow yarn membrane for selectively permeating oxygen arranged around an air feed pipe permitting the recovery of oxygen-enriched air from the end of the hollow yarn membrane, in a vessel opened at one end. CONSTITUTION:Hollow yarn membranes having selective permeability for oxygen are arranged around an air feed pipe in the assembly of hollow yarn by which oxygen-enriched air is recovered from its end part. A module is constituted by housing one or plural numbers of the hollow yarn assembly in the vessel opened at one end being constituted with an end plate 7, side plate 11 and a rack 14 taking consideration not to generate pressure drop in the oxygen- enriched air. The air forced from an air feeding port 6 passes from a hole 15 trough the space between the hollow yarns, diffused in the vessel, then discharged from the open end constituted with the rack 14. Since a large opening is formed at the open end, almost no pressure drop is generated. On one hand, a part of the air and oxygen permeates the hollow yarn, conducted to a permeated air chamber 10 through the open end 4 and withdrawn as oxygen-enriched air from an exit 8 of the permeated air.
