Re: Air Permit Applicability Request
Register Cluster 1 Decentralized Biogas Upgrading System
Dear Mr. Newland;
This letter serves to proactively provide NCDEQ Division of Air Quality (NCDAQ) with the
overview of the proposed Monarch Bioenergy (Monarch) development plans for
implementation of on -farm gas upgrading systems (GUS) for swine manure derived renewable
natural gas (RNG). Additionally, this memorandum details the utilization of oxygen injection
into anaerobic digesters for hydrogen sulfide (H2S) concentration reduction as required by the
micro -membrane GUS equipment, maximum finishing equivalents before a Section 02Q .0300
permit is required, and the emissions calculations for all proposed participants in the Register
Cluster 1 project. Monarch intends to construct multiple decentralized gas upgrading systems -
in Duplin County, NC with upgraded gas being transported via pipeline for compression and
injection into existing natural gas infrastructure. This letter serves to provide additional
information about the proposed system design and operation, and includes a discussion
regarding air permit applicability and emission rate calculations for the system.
The decentralized gas upgrading systems operating within the Register Cluster 1 system will
consist of the following key components to be installed at the farm:
• Manure conveyance improvements (in some cases: including an influent pump station
for manure delivery to the new anaerobic lagoon digester);
• An in -ground, ambient temperature anaerobic lagoon digester;
• Oxygen injection for hydrogen sulfide concentration reduction for protection of biogas
upgrading equipment.
• Wastewater piping to transfer anaerobic digester effluent to the existing manure storage
and treatment lagoon(s);
• A farm -scale micro -membrane gas upgrading system to recover methane from biogas
produced in the anaerobic digester.
• An elevated vent to release the biogas constituents not recovered by the gas upgrading
system, referred to as remnant biogas.

The process flow diagram provided below as Figure 1 depicts the operation of the anaerobic
digester and farm -scale gas upgrading system.

anaerobic digester and gas upgrading system, including venting of remnant biogas.
The components shown above will be used for enhanced manure treatment at each
participating Register Cluster 1 Gas Upgrading Facility and will produce and capture biogas
from which methane will be recovered using the farm -scale gas upgrading system. A 2017
Fact Sheet developed by the University of Maryland' discusses the efficacy of sulfur oxidizing
bacteria (SOB), their natural presence in digestion processes, the safe and acceptable
operating concentrations of oxygen in anaerobic digestion processes and the reported
hydrogen sulfide concentrations in anaerobic digesters with oxygen injection. In their fact
sheet', the University of Maryland reports that anaerobic digesters of varying feedstocks show
hydrogen sulfide concentration of 100 to 500 parts per million when oxygen injection is used.
A study done by USDA also shows that utilization of microaeration into anaerobic digesters
reduced hydrogen sulfide concentrations to below 100 parts per million on various anaerobic
digesters. Incorporation of the Cold Weather 02 Container by Energy Innovations should
reduce hydrogen sulfide concentration (-80%) from the accepted 3500 ppm raw biogas
concentration, as established by the Loyd Ray Farms Data, by two-thirds or 66% for the
protection of downstream equipment from the corrosive properties of hydrogen sulfide,
prevention of membrane fouling, and increased efficiency of gas processing and upgrading.

To ensure that all data presented in the remainder of this permit applicability determination
letter is sufficiently conservative, a 66%, or two-thirds reduction in concentration was used as
compared to the higher 80% reduction presented by Energy Innovations or the 100 to 500 part
per million range as shown in the USDA and University of Maryland reports. All participating
Register Cluster 1 farms implementing anaerobic digestion with oxygen injection for gas
upgrading and transport via pipeline are shown below in Table 1, along with the respective gas
upgrading facility they are participating in.

Once upgraded, the methane will be utilized off -farm as renewable natural gas to displace
fossil -derived natural gas via pipeline transport and injection. The remnant biogas constituents,
which are the biogas constituents not recovered by the gas upgrading system, will be vented at
each farm containing an on -farm GUS. Table 2 below provides the anticipated average

Table 2. Anticipated average biogas, renewable natural gas, and remnant biogas compositions (percent by
volume).
The anaerobic digester will be utilized for improved manure treatment and biogas production
and capture. Approximately 97% of the methane will be recovered from the biogas using the
gas upgrading system and will be used as a renewable energy resource. The remaining biogas
constituents, referred to as remnant biogas, will be vented at each farm containing an on -farm
GUS. These constituents, in addition to methane, are currently emitted from the existing
manure storage and treatment lagoon. Implementing the decentralized gas upgrading system
approach at each participating Register Cluster 1 gas upgrading facility will result in reduced
greenhouse gas emissions from each participant farm because the methane generated from
manure decomposition will be captured and utilized off -farm. The emission rates for the non -
methane remnant biogas constituents, primarily carbon dioxide and hydrogen sulfide, are
expected to be reduced as compared to the current open storage lagoon operation. The
addition of oxygen injection has been shown to lower hydrogen sulfide concentrations by 66%
compared to the current emission rates from the existing lagoon. Carbon dioxide emissions
will remain unchanged.
The tables below provide a summary of the expected actual emission rates from each
participating Register Cluster 1 gas upgrading system after installation of the anaerobic
digester and decentralized biogas upgrading system. The hourly emission rates are calculated
using the maximum rated capacity of the gas upgrading system which are stated in the
respective table captions. The annual emission rates are calculated using the expected annual
biogas production for each participating Register Cluster 1 gas upgrading system. The biogas
production will not be sufficient to operate the gas upgrading system at its maximum rated
capacity for an entire year. There will be periods when the gas upgrading system is turned off
to allow the volume of stored biogas in the anaerobic digester to increase. When a sufficient
stored volume is reached, the gas upgrading system will be turned on again to recover
methane from the biogas. During the warmest months of the year, there is expected to be
enough biogas production to operate the gas upgrading system continuously, though not
necessarily at its maximum rated capacity. During colder months, the biogas production will
decrease and the gas upgrading system will be turned off more frequently. The annual
emission rates below are calculated using the expected average biogas production from each
farm given the known manure production per animal, manure to gas conversion efficiency for
Page 4 of 11

in -ground ambient swine manure derived anaerobic digesters and published raw biogas
constituent concentrations3 within the Gas Upgrading Cluster. Given the expected gas flow,
published gas constituent data and the known reduction in hydrogen sulfide concentration from
microaeration, it can be shown that approximately 2 pounds of hydrogen sulfide is produced
per finishing equivalent when manure is collected and digested in ambient, in -ground
anaerobic digesters suggesting that raw biogas from up to 50,000 finishing equivalents could
be aggregated and upgraded before the 5 ton per year emissions limit is reached.

The construction and operation of the decentralized, farm -scale gas upgrading system at each
Register Cluster 1 gas upgrading facility does not require a Section 02Q .0300 permit. 15A
NCAC 02Q .0102(d) states that any facility whose actual emissions of particulate matter
(PM 10), sulfur dioxide, nitrogen oxides, volatile organic compounds, carbon monoxide,
hazardous air pollutants (HAPs), and toxic air pollutants (TAPs) are each less than five tons
per year and whose actual total aggregate emissions are less than 10 tons per year shall not
be required to obtain a permit pursuant to Section 02Q .0300. As shown in the tables above
and in the enclosed emission rate calculations, the actual emissions of all regulated pollutants
and HAPs and TAPs are each less than five tons per year. The total aggregate emissions for
all regulated pollutants and HAPs and TAPs are less than 10 tons per year. Since the
expected actual emission rates for each participating Register Cluster 1 gas upgrading system
fall below the thresholds defined in 02Q .0102(d), the gas upgrading facilities are not required
to obtain a Section 02Q .0300 permit for construction of the on -farm gas upgrading system.
Additionally, 15A NCAC 02Q .0102(g)(14)(K) states that animal operations not required to
have control technology pursuant to 15A NCAC 02D .1800 shall not require a permit pursuant
to Section 02Q .0300. North Carolina General Statute § 143-215.10B defines "animal
operation" to mean any agricultural feedlot activity involving 250 or more swine, with a liquid
animal waste management system. "Animal waste management system" means a combination
of structures and nonstructural practices serving a feedlot that provide for the collection,
treatment, storage, or land application of animal waste, such as an anaerobic digester. Since
none of the participating Register Cluster 1 gas upgrading facilities are required to have control
technology pursuant to 15A NCAC 02D .1800 and is defined as an animal operation, the gas
upgrading facilities are not required to obtain a Section 02Q .0300 permit for construction of
the on -farm gas upgrading system.
A Section 02Q .0700 permit to emit toxic air pollutants is not required for construction of the
on -farm gas upgrading system at any of the participating Register Cluster 1 gas upgrading
facilities. A permit to emit toxic air pollutants is required if (1) Section 02Q .0711 thresholds are
exceeded by any source not exempt pursuant to 02Q .0702 and (2) a Section 02Q .0300 or
Section 02Q .0500 permit is required. 15A NCAC 02Q .0704(b) states that the owner or
Page 10 of 11

operator of a new facility that is required to have a permit pursuant to Section 02Q .0300 or
02Q .0500 and is subject to a Section in 15A NCAC 02D shall receive a permit to emit toxic air
pollutants before beginning construction unless the source is exempt pursuant to 02Q .0702.
The on -farm gas upgrading system at each participating Register Cluster 1 gas upgrading
facility is not required to have a permit pursuant to Section 02Q .0300 and therefore is not
required to obtain a permit to emit toxic air pollutants. Additionally, 02Q .0702(a)(3) states that
a permit to emit toxic air pollutants is not required for maintenance, structural changes, or
repairs that do not change capacity of a process and do not involve any change in quality or
nature or increase in quantity of emission of any regulated air pollutant or toxic air pollutant.
The anaerobic digester and gas upgrading system at each participating Register Cluster 1
farm and each Register Cluster 1 gas upgrading facility will not increase the capacity of the
manure management process nor increase the quantity of emissions of regulated air pollutants
or toxic air pollutants.
For the reasons described above, it has been determined that neither a Section 02Q .0300
permit nor a Section 02Q .0700 permit to emit toxic air pollutants is required for the
construction and operation of the decentralized gas upgrading system at each Register Cluster
1 gas upgrading facility. Monarch respectfully requests that NCDAQ provide a determination
regarding the applicability of those Sections, and any additional Sections, should it reach a
different interpretation.
Should you have any questions or need additional information, please contact me at 919-649-
4023 or via email at [e-mail]. Thank you for your
assistance.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The DFL2 (AWS310033) RNG facility will receive manure derived biogas from both the DFL2 hog farm site and DFL1 hog farm site and will process the biogas
to create renewable natural gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digester prior to upgrading. The biogas will then be
processed using a membrane filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for operation. The
membrane Titer system will generate RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion. Off -specification
RNG will be recycled to an anaerobic digester so that it may be processed again by the facility to generate RNG. The construction and operation of the DFL2 RNG facility does not require a Section 02Q
.0300 permit. This form is being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The Carter and Sons RNG facility will receive manure derived biogas from both Carter and Sons 1 and 2 farms (AWS310160) and Bostic Jr, William M hog farm
(AWS310239) and will process the biogas to create renewable natural gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior
to upgrading. The biogas will then be processed using a membrane filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the
pretreatment filters for operation. The membrane fiter system will generate RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere
without combustion. Off -specification RNG will be recycled to an anaerobic digester so that it may be processed again by the facility to generate RNG. The construction and operation of the Carter and
Sons RNG facility does not require a Section 02Q .0300 permit. This form is being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The K&K2 RNG facility will receive manure derived biogas from both sites within the K&K1/2 Farm (AWS310725) and will process the biogas to create
renewable natural gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior to upgrading. The biogas will then be processed
using a membrane filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for operation. The membrane fiter
system will generate RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion. Off -specification RNG will be
recycled to an anaerobic digester so that it may be processed again by the facility to generate RNG. The construction and operation of the K&K1 /2 RNG facility does not require a Section 02Q .0300
permit. This form is being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The Hot Dog 2 RNG facility will receive manure derived biogas from Hot Dog Farm #2 (AWS310358) and will process the biogas to create renewable natural
gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior to upgrading. The biogas will then be processed using a membrane
filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for operation. The membrane fiter system will generate
RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion. Off -specification RNG will be recycled to an anaerobic
digester so that it may be processed again by the facility to generate RNG. The construction and operation of the Hot Dog Farm #2 RNG facility does not require a Section 02Q .0300 permit. This form is
being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The Corbett 2 RNG facility will receive manure derived biogas from Corbett Farm 1 and Corbett Farm 2 (AWS310011) and will process the biogas to create
renewable natural gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior to upgrading. The biogas will then be processed
using a membrane filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for operation. The membrane fiter
system will generate RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion. Off -specification RNG will be
recycled to an anaerobic digester so that it may be processed again by the facility to generate RNG. The construction and operation of the Corbett 2 RNG facility does not require a Section 02Q .0300
permit. This form is being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The Bond's Bacon #1 RNG facility will receive manure derived biogas from Bond's Bacon #1 (AWS310123) and Bond's Bacon #2 (AWS310365) and will
process the biogas to create renewable natural gas (RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior to upgrading. The
biogas will then be processed using a membrane filter system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for
operation. The membrane fiter system will generate RNG and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion.
Off -specification RNG will be recycled to an anaerobic digester so that it may be processed again by the facility to generate RNG. The construction and operation of the Bond's Bacon #1 RNG facility does
not require a Section 02Q .0300 permit. This form is being used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

FACILITY (Plant Site) INFORMATION
Describe nature of (plant site) operation(s): The B&C Farm RNG facility will receive manure derived biogas from B&C Farm (AWS310090) and will process the biogas to create renewable natural gas
(RNG). The biogas will first be treated with microaeration (66 % H2S Concentration reduction) within the anaerobic digesters prior to upgrading. The biogas will then be processed using a membrane filter
system to recover methane from the other biogas constituents. The membrane filter system requires H2S removal by the pretreatment filters for operation. The membrane fiter system will generate RNG
and tail gas, which consists of the biogas constituents not recovered as RNG. The tail gas will be vented to the atmosphere without combustion. Off -specification RNG will be recycled to an anaerobic
digester so that it may be processed again by the facility to generate RNG. The construction and operation of the B&C Farm RNG facility does not require a Section 02Q .0300 permit. This form is being
used to submit project information to NCDAQ for informational purposes only, not as part of a permit application.

Micro -aeration and Oxygenation System
Technology Summary
Name of Technology: Micro -Aeration and Oxygenation System
This technology introduces a small amount of nearly pure oxygen into the lagoon digester to promote the biological
oxidation of sulfur.
Type of Technology: Removal of H2S by biological consumption
Applicable:
The removal or reduction of H2S from raw biogas prior to the membrane upgarding unit improves the membrane
performance, requiring fewer membranes to achieve the comparable level of purity and methane recovery.
The production of renewable natural gas from anearobic digesters requires the near complete removal of H2S in
order to Utility Natural Gas Pipeline tariff specifications.
Achievable 1­12S Reduction
H2S reduction efficiency depends on several factors, including temperature, surface area- headspace volume ratio
and biogas residence time. Oxygen injection into a lagoon digester is expected to reduce H2S concentrations in
raw biogas by 66% - 75%, based on similar experience with dairy lagoon digesters . Laboratory testing has
achieved up to 90% H2S reduction (Khoshnevisan et al., 2017).
Typical Industrial Applications:
Oxygen/Air injection is used in continuously stirred tank reactors (CSTR), and ambient lagoon digesters. Oxygen
injection has been used extensively in dairy lagoon digesters.
Theory of Operation:
Hydrogen Sulfide (H2S) is generated in anaerobic digesters primarily through the decomposition of organic matter,
and the use of sulfate as a terminal electron acceptor by sulfate -reducing bacteria (SRB) (Ramos and Fdz-
Polanco, 2014). The pH of the digester determines the equilibrium relationship between how much H2S remains in
the liquid phase as HS-versus the amount of H2S in the digester head space.
The process [micro-aeration/oxygenation] is primarily biological: sulfide oxidizing bacteria in the digester convert
hydrogen sulfide, in the presence of oxygen, to one of three products, sulfur precipitate, sulfate, or thiosulfate, with
all three reactions thermodynamically favorable (Krayzelova et at., 2014). Oxygenation also improves digester
stability and enhances hydrolysis (the first step in anaerobic digestion).
Oxygen is preferred to air because air brings unwanted nitrogen, which dilutes the biogas heating value and
impacts renewal natural gas purity. An Oxygen generator (usually a small PSA) produces 95+% Oxygen stream.
Oxygen is injected into the head space of the digester. Sulfur oxidizing bacteria (SOB) use oxygen and H2S to
produce elemental sulfur and water. The elemental sulfur precipitates and settles in the lagoon digesters, or is
carried out of the digester in the liquid effluent.
H2S reduction at the lagoon digester improves membrane performance and decreases downstream RNG H2S
polishing media changeouts.
An Oxygen generator package unit produces a high purity oxygen stream (> 95% 02), which is injected into the

lagoon digester headspace. The injection location is in multiple locations provide a minimum residence time to
allow the oxygen to be consumed by the sulfur oxidizing bacteria. A continuous oxygen analyzer monitors oxygen
concentration in the lagoon headspace to adjust oxygen injection rate.
Oxygen Injection Flow is based on biogas production flow rates. Oxygen injection flow is added at roughly 4 times
the H2S flow rate. Biogas oxygen concentration is continuously monitored. Oxygen injection is stopped/limited to
0.2% Oxygen in the biogas to prevent product RNG quality issues. Biogas H2S is monitored periodically (1/wk) to
determine if the oxygen injection flow needs to be adjusted.
Advantages:
1. Oxygen injection reduces H2S in raw biogas
2. Oxygen injection produces little or no additional solid waste.
3. Oxygen injection improves lagoon digester stability
4. Oxygen injection improves hydrolysis which can lead to additional methane production from greater
volatile solid degradation (Jenicek et al. 2017).
5. Oxygen injection uses no solid or liquid chemicals to reduce H2S.
Disadvantages:
1. Oxygen injection can produce a flammable mixture under the digester cover, if not properly monitored and
controlled.
2. Oxygen injection can cause RNG purity issues, if not properly monitored and controlled.
3. Oxygen injection uses electric motors to generate the oxygen stream.
Other Considerations:
Micro -aeration and oxygenation provide a more cost effective reduction of H2S than traditional means, such as,
iron sponge media, ferrosorp media, water scrubbers, etc..

Birmingham. AL 35217. USA

Device Description: The OMEGA 50 is a self-contained, plug & play oxygen separation device designed to produce
up to 50 Liters per Minute (LPM) at outlet pressures starting at 20 Pounds per Square Inch (PSI). The OMEGA system is
designed specifically towards industrial applications, especially those deemed as "critical" operations that cannot allow
for equipment issues to shut down their entire operation. The OMEGA makes use of 5 individual PSA sub -systems,
which produce their own independent oxygen volumes before combining all feeds via a manifold and into a storage tank
built into the unit. Each subsystem is isolatable from both the pneumatic & electrical portions of the larger OMEGA
system, allowing a location to continue to operate at near full capacity still should an issue ever occur with one of those
smaller subsystems. The unit is housed in a 0.16" thick aluminum cabinet, which is hardy enough to resist most
abrasions/dents/heavy handling yet still lightweight enough that the device can be lifted if need be. Additionally said
aluminum cabinet also effectively doubles as a heat exchanger, as it absorbs portions on the system's internal waste
heat byproducts and allows that heat to be radiated back outside of the device into the surrounding area. The OMEGA
50 contains one 850 Cubic feet per Minute Circulation Fan mounted on the cabinet inlet filter port to help create a large
negative pressure space directly in front of the inlet, which is rapidly filled by outside fresh air before being cooled and
then rapidly accelerated into the unit's internals, where it continues to expand outwards and lower in temperature. This
helps keep a stable & consistent operating temperature once established, regardless of changes or fluctuations in the
outside ambient air's temperature. Additionally, each individual subsystem has two 100 Cubic feet per Minute circulation
fans for each compressor, designed to pull the column of cool fresh air from the top of the device downwards over the
compressor's aluminum shell, cooling the compressors, while also serving as a fresh air supply for the compression
cycle. Each subsystem has its own individual circuit breaker protection as well as hour meter, pressure relief valve built
into the compressor, a power cable (IEC), and a switch that effectively turns on/off that individual system, allowing it to
be isolated from the master device in case there were ever an issue with an individual portion. Each compressed air
supply is both rapidly cooled via an aluminum helical heat exchanger used downstream of each compressor, as well as a
hollow -yet -sealed coarse aluminum tank designed to throttle the high-pressure/high-flow compressed air stream through
a restriction before rapidly expanding it into the empty space of this tube. This results in a temporary pressure drop in the
gas supply, which massively lowers the dew point of that air supply and rapidly condenses out of the compressed air
stream almost all of the available moisture content in that air, which settles in the lowest region of the tube as a liquid,
where it's safely removed from the system via absorption into a cotton lace wick material which passes through a sized
brass orifice and exits the closed loop system where its evaporated away. Each molecular sieve bed is controlled by its
own individual Printed Circuit Board, which is universal voltage & frequency, and has a built-in transformer designed to
convert the incoming AC electricity down into 24 Volt DC power to run the two solenoid valves atop each sieve bed on a
timed interval cycle which is also stored on each board. This keeps the separation process continuing to separate for as
long as the device is receiving power. Product oxygen gas is collected from each molecular sieve bed before having its
pressure set via an individual pressure regulator mounted to each sieve bed module. These 5 feeds pass through their
own individual one-way check valves, rated to 125 PSIG & tolerant of the highly oxidizing oxygen product gas; these
prevent larger boluses of downstream oxygen from either working backwards into one of the sieve bed columns sets or
having that larger volume act as a barrier on one of the sieve bed column's product feeds, which would prevent oxygen
from passing onto downstream in the system. After passing through the check valves, these individual product feeds
combine into a single feed line using 2 Quick -Connect manifold fittings, which are composed of the same material as the
check valves and are tolerant of the oxygen gas use as well as higher pressures and flow volumes. This single product
feed line is then passed into a larger aluminum 3-gallon storage tank, where the oxygen feed expands again slightly and
loses some temperature before being compressed back together just shortly before exiting the device, which ensures no
product pressure drops or intermittent outlet flow volume. That master outlet flow volume is set by a sized fixed orifice
inside the unit just prior to exiting the OMEGA 50 oxygen outlet, but can potentially be replaced or changed out for a
rated flow meter with a built-in orifice for precise oxygen flow distribution as well as something rated for oxygen -specific
use and potentially larger flow volumes. Unit is toggled ON/OFF by either a master power switch on the side, or via a
contactor connection inside the unit that allows power control from either a PLC or some other electrical distribution
device.

Addendum 2 — Service Guide for Preventative Maintenance & Basic Operation
This is dependent on the environment it's used in & the frequency with which it's run. The following are
suggested servicing interval periods:
9550-1025: OMEGA Cabinet Filter Element (Black Foam Material inside Retainer)
o Accessed from outside of the device by removing the exterior black outer casing of the
cabinet filter retainer, with foam insert nestled in between two retainer pieces.
o Filter can be manually removed and washed with warm water/soap to remove large dirt &
dust particles. These filters can be rewashed about 5-6 times before the material loses its
shape and no longer conforms to the filter retainer holder.
o Be sure to clean every 1-3 months (sooner if run constantly or used in a dusty environment)
9800-1027: Compressor Inlet Filter (White Filter Paper)
o This is a one & done sort of filter; once dirty, it's replaced. This filter cannot be washed or
reused, and it is highly discouraged to try to modify existing filters or foam material to fit this
compressor filter's housing.
o Replace each filter element every 6-12 months (depending again on environment & run
time); this filter is after the exterior black foam filter and typically is only exposed to very fine
particles, so it does not get obstructed as often as exterior filter
A good Quarterly Service Checkup List:
• Check oxygen purity (done with a standalone oxygen analyzer)
• Check oxygen outlet pressure (done with a pressure gauge connected to the outlet feed)
• Check oxygen flow rate (done with a second flow meter; connect to oxygen outlet flow, open up fully,
and ensure it matches the flow seen on the concentrator's flow meter to make sure we aren't losing
any flow)
You can get more detailed with it if you have specialized devices:
Check each of the compressor's outlet flow volume & pressure rate. This can be done with a flow
meter that measures Cubic Feet a Minute (SCFM)/at least 150 Liters per Minute, and with a 0-60
PSI analog Pressure gauge. Please keep in mind that each check will need to be done on each
individual air compressor/molecular sieve bed to identify potential issues or faulty
equipment. While the final product purity & pressure can be measured outside the device, because
the individual feeds are combined into a single outlet product line, you will not be able to tell which
potential subsystem may be experiencing the issue that's dropping the collective product's purity,
pressure, and/or outlet flow volume. Each check is minimally invasive, low technical skillset required,
limited technical tools required, is a very short process, presents no risk to user/device/longevity,
and is a 100% reversible process.
o Compressor Pressure Check - Hook up after the compressor outlet at a test point called
P1. Connect a Tee fitting to the 3/8" OD tubing exiting from the Moisture Separator
Assembly but before each individual Sieve Column. Connect one side of the tee to this tube,
add another small section to connect the other end of the tee to the sieve bed module's
solenoid valve inlet port to "close the loop", and connect your pressure gauge to the other
unoccupied end of your test Tee fitting. Now start the oxygen concentrator up and wait a few
minutes for baseline values to be established. Monitor the compressor's pressure readings;
anything below 18 PSIG may point to a leak somewhere in that particular system, whereas
anything exceeding 40-42 PSIG may indicate a downstream obstruction that needs to be

investigated further. The compressor has a set specification on the outlet flow and at what
corresponding pressure; this will slip gradually over time as the compressor's seals and 0-
Rings break down. Most compressors can be rebuilt once this occurs and can prolong their
lifecycle, rather than be outright replaced.
o Compressor Flow Check — Take your standalone flow meter (high flow volume), and
connect it inline/in series at the P1 pressure point described above. Ensure your flow meter
does not have a flow restricting orifice in it, and open the flow on the meter up all the way.
Making sure your flow meter is connected to the Moisture Separator's outlet tube on the
meter's inlet, and making sure your connection to the molecular sieve beds downstream is
on the meter's outlet, start the unit up and wait a few minutes for those values to establish.
Now watch your flow meter as it rises and falls over the course of a 7-10 second cycle,
making note of the lowest flow point measured as well as the highest flow volume
measured, and pass that along to your service center or to the product's manufacturer for
help deciphering.
Check the internal pressures on the sieve beds
o Molecular Sieve Bed Column Pressure Check — To perform a pressure check on the
sieve beds, you'll be testing our P2 check location. Locate each molecular sieve bed column
set and find its mounted pressure regulator attachment; on one end of the regulator's
connecting tee should be a red plug fitting that occupies a'/4" OD Quick Connect fitting.
Remove this red plug while the unit is not running, and connect a 0-60 PSI pressure gauge
to this quick connect fitting; this should "close the loop" again on the PSA system. Now start
up the system, and allow
o There's an acceptable range; if it drops below said range, there's a leak that developed from
a seal breaking down. If it raises above the acceptable range, it means the beds have
hydrated and need to be replaced
Outside of these few checks and periodic servicing, there's not much more that can be done in terms of
servicing or preventative maintenance other than what is listed above. Keeping the device as cool as
possible during operation, attempting to limit moisture content in the feed air supply for the compressors if
possible, preventing frequent start/stop cycles on the running operation side, using PRO 02-provided or
verified replacement parts in the device assembly, preventing modifications to the device's
parts/operation/setup without confirming first with the manufacturer before performing, and running the
device in a PRO 02-approved setup will all greatly improve operational lifespan of the OMEGA 50 unit, as
will this preventative service & maintenance. If ever needing any questions answered, technical answers,
troubleshooting assistance, or anything similar, feel free to reach out to infoQproo211c.com and we'll direct
your inquiry to the applicable/correct department(s).
