F64B, F64L Ultra high efficiency coalescing filter
Installation & Maintenance Instructions
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 effect 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.

• 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.
