Fluid Scavenging System

Fluid from inside the separator element
is returned to the inlet valve or airend by
a scavenger tube positioned inside the
separator element, through an orifice and
tube connected to the compressor. Failure
to keep the orifice clean will result in
excessive fluid carryover. Cleaning of the
orifice should be performed as follows:
• When no fluid
is seen moving
through the
scavenge line
sight glass.

Fluid Cooler/Aftercooler (air-cooled)

The exterior of the fluid cooler/aftercooler
should be cleaned periodically to ensure
sufficient cooling capability. Dirty fins
in the cooler degrade the ability for the
cooler to work properly.
To clean the cooler fins:

Fluid Tubing

Flareless tubing is used in the fluid piping
to eliminate pipe joints and provide a
cleaner appearance.
Replacement tubing and fittings are
available; however, special installation
procedures must be followed. Your
authorized distributor has the necessary
instructions and experience to perform
these repairs.
36
• When excessive fluid carryover is
detected.
• Every fluid change.
• Once per year.
Do not ream the orifice or change the
orifice size. Do not install the orifice
reversed.
• Switch the compressor off by the main
switch and perform proper lockout/
tagout procedure.
• Clean the cooler fins using compressed
air.
Failure to install flareless tubing or
fittings correctly may result in the
tubing coming apart under pressure.
Serious injury and property damage
may result.
