Preventive Maintenance
Air Filter Element Replacement:
The air filter element provided with the OG-15/OG-20 must be replaced every six (6)
months on an average. This element helps to maintain the quality of the feed air supply
and preserve the molecular sieve inside the oxygen generators. For the
OG-15E/
OG-20E (Compressor-less) unit, the filters used on your own air compressor must be
replaced as often as necessary to maintain proper feed air quality. (Contact the
manufacturer of your compressor for recommended service intervals.)
Failure to replace the filter element on schedule will result in the warranty
becoming invalid.
Cabinet & Power Cord:
The cabinet and power cord 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. This prevents dust and dirt from building up on the machine.
Air Compressor (OG-15/OG-20 Only):
You should consider your air compressor an important part of your oxygen generating
system. In addition to changing the air filter element, maintenance is relatively simple.
The fans on either end should remain free of debris/dust. The air compressor should last
five (5) or six (6) years or longer under normal operating conditions. Eventually, however,
it will need to be re-built or replaced. 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 life. Replacement in the field is possible, but returning the unit to
OGSI or an
authorized service center is recommended.
Valve Replacements:
The best method to address this issue is to return the unit to OGSI or to an authorized
service center for repair.
