Title: Molecular Sieve Type Gas Separation Systems In supplying a high volume flow of oxygen-enriched air from a molecular sieve type gas separation system two sets of molecular sieve beds are coupled in parallel. The beds and of each bed set are cyclically subjected to a charge/adsorption on-stream phase followed by a purge/desorption regeneration phase and are controlled to operate in overlapping sequence with respect to each other. At the same time the corresponding beds are controlled to operate in antiphase relationship to each other.
