General Safety Information
1. Pressurized devices
WARNING
• Do not exceed maximum operating pressure
indicated on serial number tag.
• Make certain filter is fully depressurized before
servicing.
2. Breathing Air
• Air treated by this equipment may not be suitable
for breathing without further purification. Refer
to OSHA standard 1910.134 for breathing air
requirements.
3. Flammable gases
WARNING
While the materials of construction are compatible
with many flammable gases, the following application
limitations must be considered:
• Housing materials are slightly porous. The product
must be used in a well ventilated area in the
absence of sparks or ignition sources. Do not use
in Class 1, Division 1, Group D environments.
• The type of area - forced exhaust system used (i.e.,
high or low level) would be dependent on the gas
involved.
• Each application (other than for air or inert gas)
must be reviewed to minimize fire or explosion
hazard.

B. Piping
1. Before installing, blow out pipe line to remove scale
and other foreign matter.
2. This unit has DRYSEAL pipe threads; use pipe com-
pound or tape sparingly to male threads only.
3. Mounting (Grades 9,7,5,3) - mount so that inlet and
outlet connections are horizontal (filter bowl vertical)
to ensure proper liquid drainage.
4. Flow Direction - install so that the air flow is in the
direction of arrows on the filter head. Flow through
the element is inside out.
C. Drain Provisions (Grades 9, 7, 5, 3)
1. Manual Drain - Collected liquids must be drained on a
periodic basis. If equipped with a knurled fitting,
turn the knurled fitting on the bottom of the bowl to
your right (clockwise) to open and to your left
(counterclockwise) to close.
2. Auto Drain - Units with auto drains will automatically
discharge any water and oil collected in the bowl.
a. Filters with Internal Auto Drains - Internal Auto
Drains may be manually drained by turning the
knurled fitting to your right (clockwise) to open.
b. Filters with External Auto Drains - Housings 28 and
larger are provided with a 1/2" plug for installation
of an external auto drain. To install an External
Auto Drain, remove plug, attach nipple (and
bushing if necessary) and Auto Drain.

2.0 Operation
WARNING: Do not operate filter at pressures in excess of
Maximum Working Pressure indicated on Serial Number
Tag.
NOTE: Maximum Operating Temperature - 150°F, 66°C.
Liquid filtration above 120°F, 49°C is not recommended
since there is typically oil present in a vapor state which
passes through the filter and condenses downstream.
NOTE: Grade 1 - If operated above 100°F, 38°C may
experience less than 1000 hours of life because of greater
oil vapor content.
A. Liquid Draining - Grades 9, 7, 5, 3
NOTE: Collected liquids must be removed to ensure
proper operation.
NOTE: Depressurize slowly, to avoid filter element
damage.
1. Manual Drain - Turn to your right (clockwise) to open
and to your left (counterclockwise) to close.
2. Automatic Drain - Liquids will automatically discharge
when sufficient accumulation occurs.
a. Internal Auto Drains - These drains may be manually
drained by turning to your right (clockwise) to open
and to your left (counterclockwise) to close.
NOTE: Manually drain internal auto
drains daily to verify drain function.
4. Check that manual drains are drained periodically or
that automatic drains are functioning.
Grade 1
1. Check for an oily smell by opening the manual valve. If
an oily smell exists, the following should be checked:
a. Filter element adsorption capacity exhausted
b. Leak across element o-ring seal
c. Leak through element due to physical damage
d. Presence of liquids because of lack of or failure of
prefilters
e. Flow, pressure and temperatures outside design
conditions
f. Presence of gaseous impurities which cannot be
adsorbed
CAUTION: Methane, carbon monoxide, carbon dioxide and
various inorganic gases cannot be removed by a Grade 1
filter.
C. Flow Capacity
Maximum air flow for the various filters is indicated in
Table 1a for Corrosion Resistant Models and Table 1b for
High Pressure Models. To determine maximum air flows at
other inlet pressures, multiply flow from Table 1a or 1b by
air flow correction factor from Table 2a for Corrosion
Resistant Models and Table 2b for High Pressure Models,
that corresponds to the operating pressure at the inlet of
the filter.
NOTE: Filters should not be selected by pipe size. Select
using flow rate and operating pressure only.
B. Operational Checkpoints
Grades 9,7,5,3
1. Check pressure drop across the filter
a. Pressure differential in excess of 10 psi (0.7 kgf/
cm2) - indicates that the filter sleeve or element
should be replaced.
NOTE: Element should be changed annually or when
pressure drop reaches 10 psi (0.7 kgf/cm2), whichever
occurs first.
NOTE: Pressure drop should never exceed 50 psi
(3.5 kgf/cm2).
b. Check for sudden reduction in pressure drop. This
might indicate:
(1) Possible leak across element o-ring seal
(2) Leak through the element due to physical
damage
2. Check flow, pressure, and temperature to make
certain filter is being operated within design
conditions.
3. Check to see that filter is installed level to insure
proper drainage.

3.0 Maintenance
A. When to Replace Filter Element
NOTE: Grades 7,5,3,1 - complete element is replaced;
Grade 9 - unless separator core is damaged outer sleeve
only is replaced.
1. Grades 9,7,5,3
a. Initial (dry) pressure drop: 1 psi (0.07 kgf/cm2) to 2
psi (0.14 kgf/cm2)
b. Operating pressure drop: As filter becomes liquid
loaded (wetted), pressure drop will increase to 2 to
6 psi (0.14 to 0.42 kgf/cm2). Further pressure drop
occurs as element loads with solid particles.
FOR MAXIMUM FILTRATION EFFICIENCY, REPLACE ELEMENT
WHEN PRESSURE DROP REACHES 10 PSI (0.7 KGF/CM2) OR
ANNUALLY, WHICHEVER OCCURS FIRST.
NOTE: Pressure drop may temporarily increase when flow
is resumed after flow stoppage. Pressure drop should
return to normal within one hour.
NOTE: Grades 5 and 3 - During normal operation bottom
of foam sleeve will have a band of oil. Spotting above the
band indicates that liquids are accumulating faster than
they can be drained and that prefiltration is required.
2. Grade 1
a. Adsorption capacity - 1000 hours at rated capacity.
Element life is exhausted when odor can be de-
tected downstream of the filter.
B. Procedure for Filter Element Replacement
CAUTION: THIS FILTER IS A PRESSURE CONTAINING DEVICE.
DEPRESSURIZE BEFORE SERVICING.
1. Isolate filter assembly from system by opening
by-pass valve (if one is installed) and closing inlet and
outlet valves.
2. Depressurize filter by slowly opening manual drain
valve.
3. Disassemble filter housing
a. For High Pressure Model 24 - unscrew the collar
holding the filter bowl to the head and remove the
filter bowl and collar.
b. For Corrosion Resistant Models 12 thru 36 and High
pressure Model 32 Remove the filter bowl,
unscrewing it from the filter head by hand or strap
wrench.
4. Clean filter bowl
5. Remove and replace complete element (all models) or
sleeve only (Grade 9)
a. Removing and replacing complete element
1) Unscrew the old filter element and discard. Also
discard the small o-ring that seals the filter to
the filter assembly head.
2) Insert small replacement o-ring on top of
replacement filter element and screw
replacement element into filter assembly head.
b. Removing and replacing sleeve only (Grade 9)
1) Remove nut and bottom cap.
2) Slide disposable filter sleeve down over
separator core.
3) If necessary, unscrew separator core from filter
head and clean with soap and water.
4) Reassemble separator core to head. (Use new
o-ring supplied with replacement sleeve).
5) Slide new filter sleeve over separator core.
6) Replace bottom cap and nut.
C. Internal Auto Drain Mechanism -
(Corrosion Resistant Models only)
It is recommended that drain mechanism be replaced
annually.
