Abstract
A component gas concentrator includes an air compressor/vacuum pump, an air-tight first container containing a molecular sieve bed, the first container in fluid communication with the compressor/vacuum pump through a first gas conduit, and an air-tight second container in fluid communication with the first container through a second gas conduit. A gas flow controller such as PLC controls actuation of valves mounted to the gas conduits.
