ABSTRACT:
A molecular sieve for an oxygen concentrator free of internal filtering elements and suitable for personal use to provide substantially pure oxygen for a medical patient to breathe, having a container formed of metal with an inlet thereto and an outlet and seamed with welded seams so as to be leak-proof to moisture and able to withstand passage of hot re-activating gas, an oxygen concentrating molecular sieve material contained within the container and having a longitudinal extent concentric with the longitudinal axis of the container, filter screens and springs contained within the container extending the full diametrical extent of the container and positioned on opposite sides of the sieve material, coaxial with the longitudinal axis of the container, the sieve material being a material re-activatable by passage therethrough of a hot gas and being sandwiched between the filter screens and springs and maintained in alignment with the longitudinal axis of the container.
