Factors Affecting Fluid Life; Fluid Analysis Program - General - Quincy Compressor QSI Series Instruction Manual

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
customers using QuinSyn fluids in Quincy Compressor
Rotary Screw Compressors. This service provides
optimum drain intervals for compressors operating on
QuinSyn fluids. Monitoring of the total acid number
(TAN), barium level and/or viscosity throughout the life
of the fluid provides maximum protection to your
machine, while best utilizing the extended life features of
QuinSyn.
The fluid analysis provides historical information,
detailing 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
expectancy under normal operating conditions, it is
recommended 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 application is established. Once the
appropriate drain interval is established, the frequency of
the fluid analysis can be reduced unless operating
conditions change.
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 considerably shorten the life of the new fill
of QuinSyn fluid.
