METHOD OF MANUFACTURING A DIFFUSION AND/OR FILTRATION APPARATUS

摘要

A diffusion and/or filtration apparatus, including a housing (2) consisting of a cylindrical open-ended main part closed by two end caps (14) and being provided with an inlet (15) and an outlet (not shown) for a first fluid and at least one outlet (4) for a second fluid, said first fluid being adapted to flow through the fibers (1) of a bundle of semipermeable hollow fibers arranged between two end walls (3) within the housing (2) and said second fluid being adapted to be removed from the space outside the fibers (1) through said at least one outlet (4) for the second fluid, the ends of the hollow fibers (1) being moulded into said end walls (3) and opened by a cutting. The apparatus is characterized in that the attachment between the moulded end walls (3) and the housing (2) is reduced or eliminated by a ring (6) having a low adhesive capacity as regards the material of the end walls (3) and in that said end walls (3) are supported in the longitudinal direction of the housing (2). A method of manufacturing the above described apparatus is also disclosed and claimed.
