QuinSyn PG
QuinSyn PG is a custom blended
polyalklene glycol/ester (PAG). QuinSyn
PG is an ISO 46 viscosity fl uid with an
8,000 hour life under normal operating
conditions (exact fl uid life is determined
by the fl uid analysis program). Under
extended warranty conditions QuinSyn
PG fl uid life is rated at 8,000 hours or one
year, whichever occurs fi rst.

Applications
QuinSyn PG is the recommended fl uid 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 fl uid should be
done in accordance with Local, State,
and Federal regulations. Separation of
this fl uid from condensate will require
those separators designed to handle fl uid
emulsions. The QCS fl uid/water separator
is suitable for separation of fl uid emulsions
such as QuinSyn PG. Please contact
Quincy’s Service Department for more
details.
Fluid Analysis Program
The fl uid sampling for QuinSyn PG has
been extended to 2,000 hours because of
the superior quality and forgiving nature of
this fl uid.
NOTICE!
To m a i n t a i n e x t e n d e d w a r r a n t y
compliance, fluid samples of QuinSyn
PG must be sent to Quincy Compressor
®
Fluid Analysis a minimum of every
2,000 hours or every 6 month for light
use units.
