An air separation module comprising a bundle of hollow elongated membranes, and a pressure vessel enclosing the bundle. The pressure vessel includes an outer tube, end caps at opposite ends of the tube, and an inner tube located within the fiber bundle. The inner tube is fixedly mechanically connected at opposite ends to the end caps to form a structural spine of the pressure vessel, whereby loads acting on the air separation module are transferred between the end caps primarily by the center tube.
