Abstract

The gas separation apparatus comprises a flexible wall which is maintained in a placed position on an upper end of an adsorbant material; the volume between the wall and an upper dome communicates with one of inner and outer chambers on both sides of the adsorbant (4). The invention can be used to separate air components.
