ABSTRACT A mass transfer device (60) includes a hollow fiber bundle (10) comprising a generally cylindrical core (14) having opposed ends, a plurality of layers of hollow fiber (12) that have been wound around the core, and binding means (48a, 48b, 48c) such as double- sided pressure-sensitive tape that have been wound around the layers of hollow fiber in a plurality of longitudinally spaced locations along the core and intermediate the opposite ends of the core for providing longitudinally spaced support means for the hollow fiber bundle. The hollow fiber bundle is enclosed in a housing (62) having an inner wall (80) which defines a generally circular opening for receiving the hollow fiber bundle except that the inner wall adjacent a fluid outlet manifold (74) includes an expansion volume (82) for the hollow fibers that are adjacent that fluid outlet manifold. A screen (88) is provided adjacent the fluid outlet manifold to prevent the fibers from migrating too far into the outlet and to provide a controlled expansion.
