VSA Oxygen Generator
Low Pressure Compressed Air is introduced into the absorber by means of a PD Blower. Air is passed through the Zeolite absorber bed. As the air passes through the Zeolite, Nitrogen is preferably absorbed from the air leaving the Oxygen to pass through. Once the bed becomes saturated with Nitrogen the air flow must be stopped and the pressure reduced. This accomplished by stopping the blower and reversing its direction. In this way the one blower can act as a compressed air feed source and a vacuum compressor. As the air pressure is reduced in the absorber the Nitrogen that was absorbed on the Zeolite is released and exhausted from the system. This cycle is continued over and over to product the quantity of oxygen required. To balance out any supply disruptions a buffer tank is utilized.
