7.8 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.
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.
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.

i)
HOURS ON FLUID - These are the actual hours that the QuinSyn fluid has been in the unit since the last
fluid change
j) HOURS ON MACHINE - This is the total hours on the compressor hourmeter.
k) SAMPLE DATE - The date that the sample was taken from the compressor.
Items c) through k) are information provided by the service person supplying the fluid
for analysis. Incomplete or incorrect information will
affect the report’s accuracy
l) EVALUATION - This is a brief statement made by the technician performing the actual fluid analysis. This
statement addresses the condition of the fluid and filter. This statement will also note any problems that
need attention.
