QuinSyn Plus
QuinSyn Plus is an optional factory fill
for Quincy rotary screw compressors.
Machines ordered with QuinSyn Plus as
the factory fill will be eligible for a five-year
extended airend warranty.
QuinSyn Plus 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).
It is a synthetic hydrocarbon/ester fluid.
QuinSyn Plus is totally compatible with
QuinSyn. Machines currently running
with QuinSyn fluid can be topped off with
QuinSyn Plus with no adverse effects.
Some advantages of QuinSyn plus are:
• Superior demulsability (ability to
separate from water)
• Less susceptible to varnish
• Extremely low volatility
• Excellent corrosion protection
• Outstanding low temperature
properties
• Exceptional thermal stability
• Excellent oxidative stability
• Better gas-fluid separation

Applications
QuinSyn Plus is suited for use in rotary
screw air compressors operating in
harsh service conditions where the
fluid is exposed to higher temperatures
for extended periods of time. Fluid
thermostat temperature settings can be
elevated to assist in reducing water content
in the fluid in high humidity applications.
Please consult Quincy Service Department
for any thermostat changes.
Disposal
QuinSyn Plus is considered nonhazardous
waste. Disposal of this fluid should be
done in accordance with Local, State, and
Federal regulations. Should condensate
need to be treated, Quincy’s QIOWA fluid/
water separators are required.

QuinSyn Plus fluid is included in Quincy’s
fluid analysis program.
