DESCRIPTION
The Mist Eliminator is a coalescing type oil removal lter designed to
remove oil and water aerosols from a compressed air system. It consists
of a highly engineered, loosely packed, glass ber lter cartridge housed
in a heavy duty ASME stamped pressure vessel.
Compressed air is directed into the vessel and through the lter cartridge
where entrained water and oil aerosols are captured by the bers. The
captured particles move along the bers and coalesce into larger droplets
which gravitate to the bottom of the cartridge. Here they fall into the vessel
sump and are discharged from the system.

1.0 INSTALLATION
1.1 System cleaning
The compressed air system should be purged prior to the installation
of the Mist Eliminator.
• Solid particles should be removed from upstream lines in order to
prevent any loose dirt, rust, or scale from entering the lter and
causing a premature increase in pressure drop.
• Residual oil should be ushed from down-stream lines otherwise
considerable time will be necessary before the desired air quality
is available at the point-of-use.
1.2 Location in a compressed air system
Aftercooler/separator - It is strongly recommended that the Mist
Eliminator be installed at a point where the compressed air is as cool
as possible. In most cases the Mist Eliminator will have to be installed
downstream of an aftercooler to provide an inlet temperature below
the 150°F (65°C) maximum. While inlet temperatures as high as
150°F (65°C) are possible, this will allow some oil to remain a vapor
and pass through the lter. Lower inlet temperatures (preferably
below 120°F [49°C]) will have allowed more of the oil vapor present
to condense into liquid droplets which can then be removed by the
Mist Eliminator.
Refrigerated dryers - The Mist Eliminator should be installed down-
stream of a refrigerated dryer to remove any oil that may have
condensed inside the dryer.
Desiccant dryers - The Mist Eliminator should be installed upstream
of a desiccant dryer to prevent oil from contaminating the desiccant.
The distance between the Separator and Mist Eliminator must be
minimized to avoid over loading with water. A drop in temperature
from 110°F (43°C) to 105°F (41°C) will condense enough liquid water
to overload the Mist Eliminator.
1.3 Service clearance
Make certain that clearance exists above the lter to allow removal
and replacement of the lter cartridge.
1.4 Foundation
The Mist Eliminator can be installed on any at, level oor with suf-
cient strength to support the required weight. Mounting holes are
available for anchoring if desirable.
NOTE: Mount so that inlet and outlet connections are horizontal (vessel
is vertical). Separated and coalesced liquids drain by gravity downwards
through the cartridge and drop to and are collected in the lter sump. The
vessel must be mounted nearly plumb vertically so that drainage will not
be impeded and ltration e󰀩ciency reduced.
A typical installation will also include:
Manual or Automatic Drains
Di󰀨erential Pressure Gauge
Isolation Valves and by-pass piping
1.5 Connections
Connect inlet and outlet piping to the compressed air system.
NOTE: Flow Direction - Check to ensure that the air ow is in the
proper direction as indicated on the vessel. Air ow direction through
the lter cartridge must be from the inside out.

1.6 Drain provisions
The bottom of the pressure vessel is provided with a drain plug for
shipping purposes. Provision for manual or automatic draining is
necessary for proper operation.
Do not attempt to remove drain plug if the unit is
pressurized.
A. Manual Drain - When draining is performed manually on a
regular, periodic basis, a simple (open/shut) valve piped to
the drain port may be used to drain the vessel. When draining
manually, the valve should be opened slowly to avoid rapid
depressurization and possible cartridge damage.
B. Automatic Drain - Where regular manual draining is not per-
formed, an automatic condensate drain should be used. A variety
of drains are available from the manufacturer. Pipe automatic
drains to the drain port.
An isolation valve is recommended if servicing drain is desired
while the system is pressurized.
1.7 Di󰀨erential pressure gauge
1. Maximum voltage switching 100 volts AC/DC
Maximum switching current 0.30 AMP
Maximum carrying current 1 AMP
Contact rating: 10 VA
A gauge and installation kit are shipped separately packaged
for eld installation. Gauge may be installed on vessel or on a
nearby wall using the wall mounting bracket supplied.
NOTE: Make certain O-rings are in place on the bottom of the
gauge body.
Connect the low pressure transmission bolt (bolt next to red band
on gauge) to the gauge port at the lter outlet (downstream side
of lter).
Connect the high pressure transmission bolt (bolt next to green
band on gauge) to the gauge port at the lter inlet (upstream
side of lter).
Torque bolts to 25 +/- 5 inch-oz. Do not over tighten.
1.8 Operating limitations
1. Maximum Working Pressure:
Standard ASME Coded Units 150 psig (10.3 bar)
NOTE: If using external drain, do not exceed pressure rating of
drain.
2. Maximum Pressure Di󰀨erential - 30 psi (2.1 bar)
IMPORTANT: Under normal circumstances the pressure dif-
ferential across the lter should not exceed 30 psi (2.1 bar);
excessive pressure drop may cause lter cartridge failure. Filter
cartridge change-out recommended at 3 psi (0.2 bar).
3. Maximum Operating Temperature - 150°F (65°C)
NOTE: Temperatures above 120°F (49°C) are not recommended
since ltration e󰀩ciency may decrease.
4. Chemical Resistance - Compressed air does not normally contain
contaminants which will adversely a󰀨ect the lter cartridge.
However, some hydrocarbons, acids, bases and certain
other chemicals can attack parts of the lter assembly. These
contaminants are usually introduced through the compressor
intake under certain environmental conditions.
Provision should be made to prevent this in order to protect the
entire compressed air system. On questionable applications
consult factory prior to installation.

2.0 OPERATION
2.1 After installation slowly pressurize Mist Eliminator and inspect for
leaks. Operation is continuous and automatic.
2.2 Periodic checks are recommended to insure continuous separation
and ltration e󰀩ciency.
A.. Check pressure drop
1. Check for excessive pressure drop. Pressure drop in excess
of 3 psi (0.2 bar) indicates that the cartridge should be re-
placed.
IMPORTANT: Pressure drop should never exceed 30 psi
(2.1 bar).
2. Check for sudden reduction in pressure drop. This might
indicate a leak through the lter cartridge due to damage
from chemical attack or excessive pressure drop.
B. Check the flow, pressure, and temperature to make sure
that the lter is not being operated beyond its rated capacity.
See Section 1.8 for operating Limitations and Section 2.3 to
determine maximum ow capacity.
C. Check for proper drainage. See that manual drains are drained
periodically and that automatic drains are functioning.
2.3 Determining maximum ow capacity
Maximum air ow for the various lters at 100 psig (7 bar) is indicated
in Table 1. To determine maximum air ows at inlet pressures other
than 100 psig (7 bar), multiply ow from Table 1 by multiplier from
Table 2 that corresponds to the minimum operating pressure at the
inlet of the lter.
2.4 Maximum Operating Conditions
Maximum Working Pressure: 150 psig (10.3 bar)
ASME coded pressure vessels
Maximum Operating Temperature: 150°F (65°C)

3.0 MAINTENANCE
3.1 When to replace lter cartridge
A. Initial (dry) pressure drop: 1 psi (0.07 bar) nominal.
B. Operating pressure drop: During operation the lter cartridge
becomes liquid loaded (wetted). At rated flow conditions,
operating pressure drop will normally be: 0.5 to 1 psi (0.035 to
0.07 bar). Further pressure drop will occur only as the cartridge
becomes loaded with solid particles.
C. Change out pressure drop: IT IS RECOMMENDED THAT THE
CARTRIDGE BE REPLACED FOR MAXIMUM FILTRATION
EFFICIENCY WHEN PRESSURE DROP REACHES 3 PSI
(0.2 BAR).
NOTE: Pressure drop after ow interruption.
When ow is interrupted for several hours, the pressure drop may tempo-
rarily increase upon the resumption of ow. Normally, within one hour, the
pressure drop should return to where it was prior to stopping the ow. This
phenomenon is not cause for lter cartridge replacement. It is due both
to residual liquids contained within the cartridge “pooling” and a change
in the viscosity of these liquids due to a temporary temperature change.
3.2. Procedure for lter cartridge replacement
THIS FILTER IS A PRESSURE CONTAINING DEVICE. DEPRESSURIZE
BEFORE SERVICING.
A. By-pass the lter assembly to permit servicing.
B. Depressurize the lter assembly slowly by opening blow down
valve.
C. Remove bolts securing the lter top to the vessel.
D. Remove the top ange of the lter complete with lter element.
E. Clean the inside of the vessel and inspect for any signs of cor-
rosion.
F. Unscrew the lter element from the top ange. Discard the ele-
ment in accordance with applicable regulations.
Used elements typically hold contaminants, such as compressor
lubricants and particulate matter.
G. Thread new element into top ange.
H. Replace top ange (complete with new lter element).
I. Reinstall bolts to secure lter top.
J. Slowly repressurize lter housing and check for any leaks.
