3.0 System Description
3.1 General
The AirSep Corporation PSA Oxygen Generator is a self-contained unit
that uses Pressure Swing Adsorption (PSA) technology to produce
oxygen on site. The PSA process extracts oxygen from ambient air to
deliver product oxygen continuously to an application that requires feed
oxygen.
The oxygen generator uses compressed air from its internal air
compressor as a feed gas to produce the product oxygen. Ambient air
enters the air intake, passes through a gross particle filter to remove large
airborne particulate matter, then flows into the internal air compressor.
The air compressor pressurizes the feed air and delivers the feed air to a
heat exchanger for cooling. The cooled, pressurized air then enters one
of the adsorber vessels.
The oxygen generator uses in its adsorber vessels an inert ceramic
material called molecular sieve to separate compressed air into oxygen
and other gases. The unique properties of molecular sieve allow it to
attract, or adsorb, nitrogen physically from air under pressure. This allows
oxygen to exit the adsorbers as a product gas and flow into a mixing tank,
which maintains stable flow and purity of the product oxygen. The product
oxygen flows from the mixing tank through a pressure regulator that
allows the delivery pressure to be set as required for your application.
Finally, the product oxygen flows through a flowmeter, which allows you to
set the flow rate required for your application.
While one adsorber produces oxygen, the other depressurizes to exhaust
the waste gases it adsorbed (collected) during the oxygen production
cycle. The entire oxygen generating process is completely regenerative,
which makes it both reliable and virtually maintenance-free. The
molecular sieve does not normally require replacement when maintained
and used according to this instruction manual.
Refer to the Appendix A of this instruction manual for a detailed flow
diagram, an electrical schematic, and specifications for the oxygen
generator.
