ADJUSTMENT
1. Before applying inlet pressure to filter/regulator, turn

adjustment (2 or 5A) counterclockwise to remove all force
on regulating spring (6).

2. Apply inlet pressure, then turn adjustment (2 or 5A)

clockwise to increase and counterclockwise to decrease
pressure setting.

3. Always approach the desired pressure from a lower

pressure. When reducing from a higher to a lower setting,
first reduce to some pressure less than that desired, then
bring up to the desired pressure.

NOTE

With non-relieving filter/regulators, make pressure
reductions with some air flow in the system. If made
under no flow (dead-end) conditions, the
filter/regulator will trap the over-pressure in the
downstream line.

4. Push adjusting knob down to lock pressure setting; pull up

to release. Install tamper resistant knob (see Replacement
Items) to make setting tamper resistant.

SERVICING
1. Depress manual drain to expel accumulated liquids. Keep

liquids below element (31).
2.Clean or replace filter element when dirty.

DISASSEMBLY
1. Filter/regulator can be disassembled without removal from

air line.

2. Shut off inlet pressure. Reduce pressure in inlet and outlet

lines to zero.

3. Turn adjustment (2 or 5A) fully counterclockwise.
4. Turn bowl and bonnet counterclockwise and remove from

body.

5. Disassemble in general accordance with the item numbers

on exploded view. Do not remove the manual drain unless
replacement is necessary. Remove and replace drain only if
it malfunctions.

CLEANING
1. Clean plastic bowl with warm water only. Clean other parts

with warm water and soap.

2. Rinse and dry parts. Blow out internal passages in body

(15, 16) with clean, dry compressed air. Blow air through
filter element (31, 34) from inside to outside to remove
surface contaminants.

3. Inspect parts. Replace those found to be damaged. Replace

plastic bowl with a metal bowl if plastic bowl shows signs
of cracking or cloudiness.

ASSEMBLY
1. Lubricate seals and o-rings with o-ring grease. Apply a

small amount of anti-seize lubricant to full length of threads
on metal bowls.

2. Assemble the unit as shown on the exploded view.

TECHNICAL DATA
Fluid: Compressed air
Maximum pressure:

Transparent bowl: 10 bar (150 psig)
Metal bowl: 17 bar (250 psig)

Operating temperature**:

Transparent bowl: -34° to +50°C (-30° to +125°F)
Metal bowl: -34° to +65°C (-30° to +150°F)

** Air supply must be dry enough to avoid ice formation

at temperatures below +2°C (+35°F).

Particle removal: 5 µm or 40 µm filter element
Air quality: Within ISO 8573-1, Class 3 and Class 5

(particulates)

Typical flow with a 5µm element at 7 bar (100 psig) inlet

pressure, 6,3 bar (90 psig) set pressure, and a droop of
1 bar (15 psig) from set:
1/8" Ports: 6,2 dm

/s (13 scfm)

1/4" Ports: 6.5 dm

/s (14 scfm)

Nominal bowl size: 31 ml (1 fluid ounce)
Gauge ports:

1/8" PTF with PTF main ports
1/8" ISO Rc with ISO Rc main ports
1/8" ISO Rc with ISO G main ports

Drain connection: 1/8" pipe thread
Automatic drain operation: Spitter type drain operates

momentarily when a rapid change in air flow occurs
or when the supply pressure is reduced.

PANEL MOUNTING DIMENSIONS
Panel mounting hole diameter: 30 mm (1.19")
Panel thickness: 2 to 6 mm (0.06" to 0.25")

INSTALLATION
1. Shut off air pressure. Install filter/regulator in air line -

●

vertically (bowl down),

●

with air flow in direction of arrow on body,

●

upstream of lubricators and cycling valves,

●

as close as possible to the air supply when used as a
main line filter,

●

as close as possible to the device being serviced
when used as a final filter.

2. Connect piping to proper ports using pipe thread sealant

on male threads only. Do not allow sealant to enter
interior of unit.

3. On filters equipped with an automatic drain, slip 1/4" I.D.

flexible tube over protrusion on bottom of bowl. Avoid
restrictions in the tube. Bowl protrusion is also threaded
to accept 1/8" pipe thread fitting.

4. Turn bowl fully clockwise into body before pressurizing.
5. Install a pressure gauge or plug the gauge ports. Gauge

ports can also be used as additional outlets for regulated air.

Early Bonnet and Body - Valve seat (9), seal (10), and
gasket (37) used with early body. Early body used a stud
(32) to secure polypropylene element to the body.
Current element (31) replaces the element and stud.

Current Bonnet and Body - Valve seat (11) and seal (12)
used only with current body. Gasket (37) also used with
current body when sintered bronze element (32, 33, 34, 35)
is installed.

NOTES FOR CURRENT AND EARLY BOWLS

Current bowls use a lip on the bowl inside
diameter to retain bowl o-ring. Early bowls use
a lip on the bowl outside diameter to retain
bowl o-ring. Service kits contain current and
early bowl o-rings. The larger of the o-rings is
used on the early bowls.
