Fluid Filter; Factors Affecting Fluid Life - Quincy QSI-90 Instruction Manual

Section VI - Compressor Fluids

Fluid Filter

The fl uid fi lter is a spin on, full fl ow unit.
Replacement of the fi lter requires spinning
off the cartridge and replacing it with a
new one.
NOTICE!
Use genuine Quincy replacement
filters only.

Factors Affecting Fluid Life

To protect your investment, check for the
following, which can affect the long life of
QuinSyn:
1) High operating temperatures
2) Contaminants:
a. Other fl uids
b. Strong Oxidizers such as:
• aci ds
• sul fur
• chl orine
• burnt fuel -
i.e. exhaust from: forklifts, boilers,
jet aircraft
• ni trogen o xides
• o zone
• w elding f umes
• plastic molding fumes
c. A mmonia
d. Solvent fumes:
• chl orinated degr easers
• i nk so lvents
e. Airborne dust and particles
f. Paper digester fumes

The initial fi lter change should occur
after the fi rst 500 hours of operation.
During normal service, the fi lter cartridge
should be replaced under the following
conditions, whichever occurs fi rst:
♦
as indicated by the fluid filter
maintenance indicator when the fluid is
at normal operating temperature
♦
every 2,000 hours
♦
every fluid change
NOTICE!
The fluid filter maintenance indicator
may read high upon start up on
cool mornings due to sluggish fluid
creating higher than normal differential
pressures. Monitor indicator after the
fluid warms up.
Locate your compressor in the coolest
area possible. For every 18°F above
195°F, the operating life of any fl uid is
reduced to about half that at 195°F. Some
mineral oils begin to form varnish at
temperatures above 200°F. QuinSyn fl uids
are more forgiving than mineral oil at high
temperatures. QuinSyn XP is designed to
operate at sustained temperatures above
200°F. The life of other QuinSyn fl uids will
be shortened at high temperatures.
Air intake should provide contaminant-
free, cool air. A Quincy heavy-duty intake
fi lter will reduce the risk of abrasion and
increased wear. An air fi lter does not
eliminate reactive gases. Inspect your fi lter
monthly and replace as required.
