Check Valves
The check valves ensure that product gas does not flow back into the adsorbers.
Circuit Board
The circuit board controls the cycle time and sequence of operation of the solenoid
and drain valves.
Coalescing Filter
The coalescing filter removes condensed water, oil vapor, and other contaminants
from the feed air before the air enters the adsorbers.
Feed Air Regulator
The feed air regulator is set at the AirSep Corporation factory. The feed air regulator
controls the amount of air pressure at which the oxygen generator cycles.
Filter Drain Valve
This automatic valve removes moisture from the filters through tubing connected to
an outlet at the back of the oxygen generator.
Flow Controller (Not available on AS-20 and AS-450 — AS-1000 models)
The flow controller ensures consistent flow of the delivered product oxygen.
Manual Filter Outlet Valve
This manual valve controls the flow of feed air from the feed air regulator after the
filters to the automatic feed air valves.
Manual Inlet Valve
This manual valve controls the flow of feed air from the air compressor to the filter
assembly.
Particulate Filter (Not available on AS-20 model)
The particulate filter, or prefilter, removes particulates from the feed air before the
air enters the coalescing filter and then the adsorbers.
Pressure Switch
When the oxygen generator operates in Auto mode, the pressure switch monitors
the oxygen pressure in the oxygen receiver. When the pressure in the oxygen
receiver increases to approximately 380-415 kPa (55-60 psig), the pressure switch
circuit closes and the oxygen generator starts a timed shutdown that stops the unit
at the end of the shutdown sequence. When the pressure in the oxygen receiver
decreases to approximately 310 kPa (45 psig), the pressure switch opens to
activate the oxygen generator, and oxygen production begins. When the oxygen
generator operates in Manual mode, the pressure switch circuit remains open and
the oxygen generator cycles continuously.
