OX-12
12-SCFH Oxygen Generator (Concentrator)
Installation and Operation Manual
OX-12 Oxygen Generator Manual
Cautions, Warnings and Hazards
Oxygen is a powerful oxidizing agent; it can cause fire or explosion. Observe strict
cleanliness procedures when fabricating and connecting the oxygen piping. It is
imperative that oxygen systems be properly cleaned and inspected to insure that
no combustible materials remain in the connecting piping and fittings. Do not
allow the free flow of oxygen from the Oxygen Generator or from any point on the
oxygen manifolding.
Ensure that the Oxygen Generator is in a well-ventilated area. If the space is occupied,
sufficient ventilation must be provided to prevent the accumulation of low oxygen
concentration waste gas in the space. Approximately 6 air changes per hour are
necessary.
Do not allow rain or condensation to contact the Oxygen Generator. The Oxygen
Generator is not weather proof. The unit must be operated indoors or in an enclosure
in a noncondensing environment.

OX-12 Oxygen Generator Manual
Introduction
The operation of the Oxygen Generator is based on the pressure swing adsorption
(PSA) cycle using synthetic zeolite molecular sieve. The Oxygen Generator is capable
of delivering oxygen flows up to 12-standard cubic feet per hour (SCFH) at over 90% by
volume oxygen concentration. The main components of the Oxygen Generator are an
Oxygen Concentrator Module and an oil less air compressor.
Typical applications for the Oxygen Generator include aquaculture and feed gas for
ozone generation. Ozone Solutions can supply oxygen generators, sub-systems and
components for generators in many capacities.
Installation
Place the unit in a manner that allows for sufficient access space around the Oxygen
Generator to perform normal maintenance and service. Also ensure there will be a free
flow of cooling air around the unit. Connect the unit to a grounded power source rated
for the voltage and current requirements stated on the label on the unit.
IMPORTANT: The location of the Oxygen Generator must be well ventilated. Contact
Ozone Solutions if further assistance is needed.
IMPORTANT: Choose a location for the Oxygen Generator that does not allow rain or
condensation to contact the unit. The Oxygen Generator is not weather proof. It must
be operated indoors or in an enclosure in a noncondensing environment.

Oxygen Hook-up
The oxygen outlet connection is 1/8-inch female National Standard Pipe Thread (FPT)
and is located on the front of the Oxygen Generator. The hex-nut bulkhead fitting
should be stabilized with a 7/8-inch wrench to prevent rotation when making your
connection to the unit.
IMPORTANT: Oxygen is a powerful oxidizing agent; it can cause fire or explosion.
Observe strict cleanliness procedures when fabricating and connecting the oxygen
piping. It is imperative that oxygen systems be properly cleaned and inspected to
insure that no combustible materials remain in the connecting pipe and fittings.
If you are not familiar with oxygen cleaning procedures, refer to the Compressed Gas
Association documents G-4.1 “Cleaning Equipment for Oxygen Service” and G-4.4
“Industrial Practices for Gaseous Oxygen Transmission and Distribution Piping
Systems.”
IMPORTANT: Do not allow the free flow of oxygen from the Oxygen Generator.
Ensure that the oxygen flow is measured and controlled to rates that do not exceed
rated capacity.
Operation
To start the Oxygen Generator, connect the unit to a grounded power source rated for
the voltage and current requirements stated on the label on the unit. Push the toggle
switch on the front panel to the up position.
Set the outlet oxygen flow to 12-SCFH (5.5-SLPM) or less.
IMPORTANT: Ensure that the Oxygen Generator is in a well-ventilated area. If the
space is occupied, sufficient ventilation must be provided to prevent the accumulation
of low oxygen concentration waste gas in the space. Approximately 6 air changes per
hour are necessary.
IMPORTANT: The flow meter installed on the Generator is set to read accurately when
the discharge is to atmospheric pressure. If the actual discharge pressure is
substantially above atmospheric pressure, the reading can be adjusted to determine the
precise flow rate, according to the following formula (using psig):
Please contact Ozone Solutions if additional assistance is required.
Do not allow the oxygen product to vent freely. Do not exceed rated capacity.

Maintenance
Compressors require a rebuild after 5,000 to 12,000-hours of operation, depending on
environmental conditions.
See the Service Parts section for information on compressor rebuild kits and inlet filters.
