Pressure Regulator and Lubricator Package
Use the adjustment knob
of the pressure regulator to
adjust the air pressure going
through the pump. It must be
pulled up before adjusting.
Check the oil atomizer, lo-
cated near the air line and
behind the regulator, to verify
that it is running at approxi-
mately one drop every 2-3
minutes. This atomizer feeds
lubrication to the air line and
should be relled with ISO
32 SAE10 Airline Lubricating
(mineral) Oil when necessary. Use of the wrong oil may
cause o-ring failure. If there is oil leaking from the muf-
er, adjust the oil atomizer valve.
Air-Diaphragm Pump
The 1/2” air diaphragm pump
is the heart of the system and
should be well maintained. Ze-
bra has chosen this particular
brand pump for its durability and
ease of maintenance.
In normal operation, it will emit a
thumping sound. The faster the
sound, the faster uid is moving
through the system.
The pump can handle lifting uids 15 feet on the intake
side. However, it develops great pressures on the out-
put side, and care must be taken to never try to restrict
the uid ow in any way.
For more information on the pump, please refer to the
Third Party Information in the Appendix of this manual.
Coalescing Tank
The coalescing tank is made of polyethylene to with-
stand oils and coolant. It is not made to withstand
punctures or shock, so care must be taken to prevent
damage.
It can hold approximately 19 gallons of liquid. You will
need to prell the tank with oil only in the event that your
application requires no oil to be “removed” from the tank
in service.

Bafed Anti-Turbulence System (BATS)
The BATS is made of PVC and acts to remove air
bubbles from the incoming uid. In so, turbulence is
lessened in the coalescing tank, aiding in the separation
of oil and water-based uids.
Pressurized Filtered Oil Return System
The oil return piping system will remove oil from the
coalescing tank, circulating it through the pump to the
ultralter. After ultraltration, it is then pumped under
pressure to your holding vessel.
Ultralter
The Sierra is equipped with a 5µ ultralter,
standard. This lter cartridge is made of
cellulose and should not be reused, but re-
placed, when necessary. Reuse of this lter
may cause damage to the pump and void all
warranties.
Periodically inspect the cartridge to deter-
mine whether it needs replacement. Another
good indication for replacement is if the
system requires more than 40psi to maintain the proper
ow rate. Also verify that the o-ring is free of debris be-
fore reinstallation.
Overll Prevention Line
This line, which is the 1/4” clear hose, recirculates up to
10% of the uid back through the right side of the pump
to prevent the coalescing tank from overowing.
Ball Valve for Waste Fluid Discharge
The waste uid, whether it’s water or coolant, will settle
on the bottom of the coalescing tank. It will be necessary
to manually discharge this uid to a waste container be-
fore its level reaches that of the oil return piping. NOTE:
Waste waters will recirculate through the ultralter and
into your holding vessel if not regularly discharged.
