Section VII - Compressor Fluids

QuinSyn PG

Effective on orders entered on June 1, 2000 and later,
Quincy's factory fill fluid changed from QuinSyn to
QuinSyn PG. Orders placed prior to June 1, 2000
shipped with QuinSyn.
QuinSyn PG is a custom blended polyalklene glycol/ester
(PAG). QuinSyn PG is an ISO 46 viscosity fluid with an
8,000 hour life under normal operating conditions (exact
fluid life is determined by the fluid sampling program)
and is the chosen fluid for Quincy's new five-year airend
warranty effective June 1, 2000 (see Blue Alert #566).
Under extended warranty conditions QuinSyn PG fluid
life is rated at 8,000 hours or one year, whichever occurs
first.
Typical Properties of QuinSyn PG ISO 46
Viscosity @ 100°F ASTM D445
Viscosity @ 210°F ASTM D445
Viscosity Index ASTM D2270
Specific Gravity 60/60
Flash Point ASTM D92
Fire Point ASTM D92
Applications
QuinSyn PG is the recommended fluid in high humidity
applications due to its ability to hold water. QuinSyn PG
is best suited for applications where high humidity exists
and the machine cannot be shut down to drain water from
the reservoir.

Disposal
QuinSyn PG is considered nonhazardous waste. Disposal
of this fluid should be done in accordance with Local,
State, and Federal regulations. Separation of this fluid
from condensate will require those separators designed to
handle fluid emulsions. The QIOWA fluid/water
separator is suitable for separation of fluid emulsions
such as QuinSyn PG. Please contact Quincy's Service
Department for more details.
Fluid Analysis Program
The fluid sampling for QuinSyn PG has been extended to
2,000 hours because of the superior quality and forgiving
nature of this fluid. The new five-year extended warranty
with QuinSyn PG requires 2,000 hour sampling as a
condition of maintaining the warranty.

of QuinSyn PG must be sent to Quincy

Because this fluid differs from QuinSyn, different
methods are employed to evaluate the fluid in the
sampling program. Primary concerns with this fluid are
the total acid number (TAN) and barium levels. QuinSyn
PG will not be condemned on water percentage nor
antioxidants but will be condemned on low barium and
high TAN values. The barium in the fluid acts as a
corrosion inhibitor, therefore we have set low limits for
this additive (see page 42 for limits).
