QuinSyn PG
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 analysis program) and is the
chosen fluid for Quincy’s new five-year
airend warranty effective June , 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.

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.
notiCe!
To maintain warranty compliance, fluid
samples of QuinSyn PG must be sent
to Quincy Compressor
®
Fluid Analysis
a minimum of every 2,000 hours.
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 60 for
limits).
