RECEIVER--SEPARATOR SYSTEMS
WARNING
High pressure air can cause serious injury or
death from hot oil and flying parts. Always relieve
pressure before removing caps, plugs, covers or
other parts from pressurized air system.
* Open service valve and manual blowdown valve
at end of machine.
* Ensure pressure is relieved, with BOTH:
-- Discharge air pressure gauge reads zero (0).
-- No air discharging from service valve or
manual blowdown valve.
When draining oil, use valve at bottom of separator
tank.
When adding oil, remove and replace (make tight)
plug on side of separator tank.
In the compressor lubricating and cooling system,
separation of the oil from the compressed air takes
place in the receiver--separator tank. As the com-
pressed air enters the tank, the change in velocity and
direction drop out most of the oil from the air.
Additional separation takes place in the oil separator
element which is located in the top of the tank.
Any oil accumulation in this separator element is
continuously drained off by means of a scavenge tube
which returns the accumulated oil to the system.
The life of the oil separator element is dependent upon
the operating environment (soot, dust, etc.) and
should be replaced every twelve months or 2000
hours. To replace the element proceed as follows:
* Ensure the tank pressure is zero.
* Disconnect the hose from the scavenge tube.
* Remove scavenge tube from tank cover.
* Disconnect service line from cover.
* Remove cover, element and inner shell.
* Remove any gasket material left on cover or tank.
* Install new gasket, inner shell and new element.
NOTICE
Do not remove staples from the elementgasket.
The staples provides continuity between the mat-
ing components.
*Place a straightedge across top of element and mea-
sure from bottom of straightedge to bottom of ele-
ment (See Fig. 4.1).
*Replace scavenge tube in cover (cover is still off of
tank).
*Measure from bottom of cover to end of scavenge
tube
(See Fig. 4.2). Measurement should be from
1/8” to 1/4” less than the element measurement. If
not, cut to size, being sure to cut in an approximate 45
_
angle.
*Remove scavenge tube.
*
Reposition cover (use care not to damage gaskets).
*Replace cover mounting screws: tighten in a
crisscross pattern to recommended torque value.
*Reconnect service line. Replace scavenge tube.
Re--connect hose.
*Close service valve. Start unit and look for leaks.
When replacing the element, the scavenge lines,
orifice, filter, and check valve should be thoroughly
cleaned and the oil changed.
