Operation
On exceptionally dirty lines it may be neces-
sary to clean the pre-ilter 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 ilter 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 ilter.
Resistance to air low will gradually increase
as the ilter element collects solid particles.
The pressure differential across the element
should not be allowed to exceed 0,7 bar
(10 psi) or damage to the element may
occur.
Servicing
Air Service equipment should be initially
maintained annually. Use, quality of air and
condition at examination may indicate ad-
justment of the maintenance interval.
1. Open manual drain to expel accumulated
liquids. Keep liquids below element (3).
2. To operate automatic drain manually, lift
operating pin in bottom outlet with a blunt
rod.
3. Clean or replace ilter element when dirty.

Disassembly
1. Shut off 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 ilter section
unscrew the ilter bowl (10) and remove
with bowl o-ring (5).
4. Remove coalescing element (3) by hand.
5. Remove pre-ilter element (16).
6. Unscrew top bowl and remove top
element (18).
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-ilter element
(16) 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 (3) will need re
newing if pressure drop becomes excessive.
It is not designed to be cleaned.
Replace carbon pack (18) with new
element if discoloured due to oil
adsorption. When replacing or renewing
top element, wipe main ilter body
thoroughly to remove all traces 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 (10) 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 (10) fully clockwise into body.
Caution
Water vapor will pass through these units
and could condense into liquid form down-
stream as air temperature drops. Install an
air dryer if water condensation could have
a detrimental effect on the application.
Warning
These products are intended for use in
industrial compressed air systems only. Do
not use these products where pressures and
temperatures can exceed those listed under
Technical Data.
Polycarbonate plastic bowls can be dam-
aged and possibly burst if exposed to such
substances as certain solvents, strong
alkalies, compressor oils containing es-
ter-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 luids other
than air, for non industrial applications, or for
life-support systems consult Norgren.
