Abstract
A modular, pneumatically parallel arrangement of sieve beds for a pressure swing adsorption gas concentration apparatus is described. A manifold head structure having a plurality of ports, channels and components which are connected together forms the pneumatic circuit for the pressure swing adsorption process. The manifold structures are arranged so as to be simply connected together to modularly form a pressure swing adsorption apparatus of the desired capacity.
