Preventive Maintenance
Frame Inlet Air Filter Element Replacement:
The Frame Inlet Air Filter Element provided with the MOGS-100 must be replaced every
three to six months, depending on the amount of dust and debris in the operating location.
The element helps to maintain the quality of the feed air supply and to keep the inside of
the machine relatively clean. This filter element is accessed by reaching under the front
of the machine and pulling it forward. While these can be supplied by
OGSI
as part of a
spares kit, the easiest way to get replacements is by going to any hardware store and
buying 16

furnace filters.
Failure to replace the filter element on schedule will result in the warranty becoming invalid.
Inlet Air Filter Element Replacement:
The air filters (2) keep dust and dirt from entering the air compressors and need to be
changed twice a year in normal environments to maintain system performance.
In areas of excessive dust and oil, it is important to change the filters more often.
A quarterly change is recommended. These filter elements are accessed by removing the
wing nuts on the black filter housing covers at eye level inside the front door. These can
also be supplied by
OGSI
as part of a spares kit.
Cabinet:
The cabinet should be occasionally washed down with a sponge or clean rag and some
soapy water. Avoid the use of ammonia or other strong chemical based cleaning
solvents. The intention is to avoid dust and dirt from building up on the machine.
Ammonia in particular will contaminate the molecular sieve inside the oxygen generators
and result in poor unit performance.
Air Storage Tank Drain:
When the system is first installed it is a good idea to open the solenoid valve drain
located at the bottom of the grey air tank every few days. If more than a few drops of
water are drained from the tank, it implies that your location is very humid and you
should check the storage tank regularly (every few days). If there is very little or no
water drainage, then the storage tank can be checked less frequently (once every month).
The idea is to prevent water from getting into the oxygen generator sieve beds. This is
not needed for units with an auto-drain.
Air Compressors:
The Air Compressors should last four (4) to five (5) years or longer under normal operating
conditions. Eventually, they will need to be re-built or replaced. This operation is usually
needed after 8000 – 10,000 hours. Oxygen purity and flow rate along with feed air
pressure delivered to the sieve beds will all be indicators that the air compressor has
expended its useful life. Replacement in the field is possible and takes about 30 minutes
per compressor.
