Section VII - Compressor Fluids
Factors Affecting Fluid Life
To protect your investment, check for the following,
which can affect the long life of QuinSyn:
1) High operating temperatures
2) Contaminants:
a. Other fluids
b. Strong Oxidizers such as:
• acids
• sulfur
• chlorine
• burnt fuel -
i.e. exhaust from: forklifts, boilers, jet aircraft
• nitrogen oxides
• ozone
• welding fumes
• plastic molding fumes
c. Ammonia
d. Solvent fumes:
• chlorinated degreasers
• ink solvents
e. Airborne dust and particles
f. Paper digester fumes
Locate your compressor in the coolest area possible. For
every 18°F above 195°F, the operating life of any fluid
is reduced to about half that at 195°F. Some mineral
oils begin to form varnish at temperatures above 200°F.
QuinSyn fluids are more forgiving than mineral oil at
high temperatures. QuinSyn XP is designed to operate
at sustained temperatures above 200°F. The life of other
QuinSyn fluids will be shortened at high temperatures.
Air intake should provide contaminant-free, cool air.
A Quincy heavy-duty intake filter will reduce the risk
of abrasion and increased wear. An air filter does not
eliminate reactive gases. Inspect your filter monthly and
replace as required.

Fluid Analysis Program - General
Quincy's fluid analysis program is offered to all custom-
ers using QuinSyn fluids in Quincy Compressor Rotary
Screw Compressors. This service provides optimum
drain intervals for compressors operating on QuinSyn flu-
ids. Monitoring of the total acid number (TAN), barium
level and/or viscosity throughout the life of the fluid pro-
vides maximum protection to your machine, while best
utilizing the extended life features of QuinSyn.
The fluid analysis provides historical information, detail-
ing items such as hours on the fluid, viscosity and total
acid number (TAN). Should results appear unusual
or suspicious, a detailed analysis can pinpoint specific
contaminants. A detailed report is furnished to you, your
Quincy Distributor and the Quincy Compressor factory
upon completion of the fluid analysis.
Although QuinSyn fluids are rated by hours of life ex-
pectancy under normal operating conditions, it is recom-
mended that fluid samples be taken every 500 to 2000
hours and sent to Quincy Compressor Fluid Analysis until
a history of performance in a specific compressor applica-
tion is established. Once the appropriate drain interval
is established, the frequency of the fluid analysis can be
reduced unless operating conditions change.
NOTICE!
All Quincy Compressor extended airend warranty
programs require that fluid samples be sent to
Quincy Compressor Fluid Analysis a minimum
of every 2,000 hours.
The depletion of antioxidants, change of viscosity, barium
and acid levels all occur with time. It is extremely
important to change QuinSyn before the antioxidants are
completely depleted. If the fluid is left in the compressor
beyond its useful life, removing all of the spent fluid is
difficult. The oxidation products remaining can consider-
ably shorten the life of the new fill of QuinSyn fluid.
