Installation
1. Install unit vertically in air line - upstream of
lubricators and cycling valves, with air flow in
direction of arrow on body, as close as
possible to the device being serviced.
2. Before assembling the basic unit into the yoke
the port seal o-rings should be lightly smeared
with o-ring grease.
3. Locate clamp ring under lugs on top of yoke,
oer basic unit into yoke with directional
arrows correctly aligned (an interference fit
prevents assembly if misaligned) before
engaging and fully tightening the clamp ring.
4. Turn bowl fully clockwise into body before
pressurizing.
5. Auto-drain units may be fitted with a short
drain pipe and connector, minimum 5 mm
bore, to the G1⁄8 bottom outlet.
6.Install a Norgren general purpose filter with a
5 μm element upstream of the oil removal filter
to obtain maximum element service life.
Operation
On exceptionally dirty lines it may be necessary
to clean the pre-filter element at 90 day intervals.
Do not exceed Maximum Flow rating or
excessive pressure drop will result or oil carry
over may occur. The top filter element acts as
absorbant pack to remove any small traces of oil
or hydro-carbon gases which might be carried
over from the lower bowl. These elements also
provide protection in the event of any failure of
the lower filter. Resistance to air flow will grad-
ually increase as the filter element collects solid
particles. The pressure dierential across the
element should not be allowed to exceed
Servicing
Air Service equipment should be initially
maintained annually. Use, quality of air and
condition at examination may indicate
adjustment of the maintenance interval.
1. Open manual drain to expel accumulated
liquids. Keep liquids below element (46, 50).
2. To operate automatic drain manually, lift
operating pin in bottom outlet with a blunt rod.
3. Clean or replace filter element when dirty.
Disassembly
1. Shut o inlet pressure. Reduce pressure in
inlet and outlet lines to zero.
2. For ease of maintenance the unit can be
removed from the yoke by unscrewing the
clamp ring, which will jack the unit out
downwards.
3. To disassemble the lower filter section
unscrew the filter bowl (14, 21, 28, 37) and
remove with bowl o-ring.
4. Remove coalescing element (46, 50) by hand.
5. Remove pre-filter element (49, 54).
6. Unscrew top bowl and remove top element
(8).
7. Disassemble in general accordance with the
item numbers on exploded view. Do not
remove the drains unless replacement is
necessary. Remove and replace only if they
malfunction.

Cleaning
1. Partial cleaning of the pre-filter element (49,
54) is possible by washing the element in
soapy water and blowing out thoroughly
with compressed air. Replacement by a clean
element is recommended.The main

coalescing element (46, 50) will need
renewing if pressure drop becomes excessive.
It is not designed to be cleaned. Replace
carbon pack (8) with new element if
discoloured due to oil adsorption. When
replacing or renewing top element, wipe main
filter body thoroughly to remove alltraces of oil
and renew o-ring. If top element becomes
saturated with oil in a short period, the main
element or o-ring may be faulty and should
be replaced. Clean plastic bowl (31, 40) with
warm water only. Clean other parts with warm
water and soap. 2. Rinse and dry parts. Blow
out internal passages in body with clean, dry
compressed air. 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 o-rings with o-ring grease.
2. Assemble the unit as shown on the exploded
view.
3. Turn bowl or bowl with guard (14, 21, 28, 37)
fully clockwise into body.
Caution
Water vapor will pass through these units and
could condense into liquid form downstream as
air temperature drops. Install an air dryer if water
condensation could have a detrimental eect on
the application.
WARNING
Polycarbonate plastic bowls can be damaged
and possibly burst if exposed to such
substances as certain solvents, strong
alkalies, compressor oils containing ester-based
additives or synthetic oils. Fumes of these
substances in contact with the polycarbonate
bowl, externally or internally, can also result in
damage. Clean with warm water only.
Use metal bowl in applications where a plastic
bowl might be exposed to substances that are
incompatible with polycarbonate.
Before using these products with fluids other
than air, for non industrial applications, or for
life-support systems consult Norgren.
Use in potentially explosive atmospheres

• Only non-flammable gasese to be used as a
medium.
• Surface temperature dependant on process
fluid temperature and ambient temperature -
must be below the ignition temperature of the
flammable gas or dust.
• Earth unit and/or pipework to avoid
electrostatic discharge.
• Precautions should be taken to prevent hazard
from adiabatic compression.
• Use wet cloth for cleaning.
• Protect the unit from object falling onto it.
• Avoid contact with corrosive environment.
• For servicing the unit it is recommended to
carry out this work outside of the danger
zone.
• For details of ignition hazard assessment
contact Norgren.
