e2 Electronic Oxygen Concentrator

The e2 draws in room air and separates oxygen from the air utilizing the Pressure Swing Absorption process and creates medical grade oxygen for the patient. The e2 Oxygen Concentrator compresses the medical grade oxygen to 60 PSI and stores the oxygen in a reservoir for supply on demand.  Once the reservoir pressure builds to 60 PSI, the compressor shuts down and enters Power Saving Mode.  As the e2 Oxygen Concentrator requires oxygen, it supplies a regulated steady flow of oxygen at 50 PSI.  As the reservoir is depleted, the compressor energizes and starts the process over.
