QuinSyn Plus

Effective on orders entered on December 1, 2000 and
later, Quincy Compressor began offering our new
extended life synthetic fluid, QuinSyn Plus. QuinSyn
Plus is an optional factory fill for 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 QIOW fluid/water separators
are required.
Fluid Analysis Program
QuinSyn Plus fluid is included in Quincy's fluid analysis
program.
To maintain extended warranty compliance, fluid
samples of QuinSyn Plus must be sent to Quincy
Compressor Fluid Analysis a minimum of every
2,000 hours.
