3.0 Generator Description
3.1 General
The AirSep Corporation PSA Oxygen Generator is a self-contained unit that utilizes
Pressure Swing Adsorption (PSA) technology to produce oxygen on site. The
oxygen generator uses compressed air to produce oxygen. Air enters the Oxygen
Generator through an external air intake gross particulate filter. This filtered air
enters the compressor via a suction resonator, which quiets the compressor’s
suction sound. Pressurized air then exits the compressor and passes through a
heat exchanger. The heat exchanger reduces the temperature of the compressed
air. Next, a two-way solenoid feed valve directs the air into 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. Each adsorber produces oxygen for approximately eight seconds.
Oxygen exits the adsorbers through a pressure regulator, flow control valve, and
flowmeter. The flow control valve, which is part of the flowmeter, controls the
amount of oxygen delivered to the 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.
