Particulate Filter (Not Available On As-A Models); Coalescing Filter; Feed Air Regulator; Filter Drain Valve - AirSep AS-A Instruction Manual

Particulate Filter (Not available on AS-A models)

The particulate filter, or prefilter, removes particulates from the feed air before the
air enters the coalescing filter and then the adsorbers.

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. 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 without consulting AirSep Corporation.

Filter Drain Valve

This automatic valve removes moisture from the filters through tubing connected to
an outlet of the filters. In higher series models, the automatic valve is not present
instead the moisture removal operation is controlled by the PLC.
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. It is named manual feed # 2 valve (V-2).
Automatic Feed Air Valves
The automatic feed air valves control the flow of the feed air as the air enters the
adsorbers.
Automatic Waste Valves
The automatic waste valves control the flow of waste gas as it exits the adsorbers.
Pneumatic Equalization Valve (AS-D+ — AS-P models only)
The pneumatic equalization valve enables the pressure in the adsorbers to
equalize after the product oxygen exits from one of the adsorbers.
Automatic Product Valve
The automatic product valve controls the flow of product oxygen from the
adsorbers. This valve is manual in AS-D+ thru AS-P models and is named manual
product valve (V-3).
Check Valves (Not available on AS-D+ models)
The check valves ensure that product gas does not flow back into the adsorbers.
4-6
Setting the Feed air regulator to a value such that the
maximum oxygen generator cycle 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.
