20 AS-D+—AS-P Series Instruction Manual
AirSep Corporation
Manual Air Inlet Valve (V-1)
This manual valve controls the ow of feed air from the air compressor to the lter
assembly. It is named manual feed # 1 valve (V-1).
Particulate Filter
The particulate lter, or prelter, removes particulates from the feed air before the
air enters the coalescing lter and then the adsorbers.
Coalescing Filter
The coalescing lter 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. It controls the maximum
oxygen generator cycle pressure. The setting of the regulator is customized as per
the demand of oxygen for your application. Please ensure that the feed air regulator
setting is not changed before consulting AirSep Corporation.
Setting the feed air regulator to a value such that the maximum
oxygen generator cycle/bed pressure is 80 psig or more can cause
severe damage to the molecular sieve in the adsorbers which will
not be covered under AirSep’s warranty.
Filter Drain Valve
This automatic valve removes moisture from the lters through tubing connected to
an outlet of the lters.
Manual Filter Outlet Valve (V-2)
This manual valve controls the ow of feed air from the feed air regulator after the
lters to the automatic feed air valves. It is named manual feed # 2 valve (V-2).
Automatic Feed Air Valves
The automatic feed air valves control the ow of the feed air as the air enters the
adsorbers.
Automatic Waste Valves
The automatic waste valves control the ow of waste gas as it exits the adsorbers.
Pneumatic Equalization Valve
The pneumatic equalization valve enables the pressure in the adsorbers to equalize
after the product oxygen exits from one of the adsorbers.
