F35 Particulate Filter
IS-F35
Installation
1. The filter should be installed with reasonable accessibility
for service whenever possible – repair service kits are
available. Keep pipe or tubing lengths to a minimum with
inside clean and free of dirt and chips. Pipe joint compound
should be used sparingly and applied only to the male
pipe – never into the female port. Do not use PTFE tape
to seal pipe joints – pieces have a tendency to break off
and lodge inside the unit, possibly causing malfunction.
Also, new pipe or hose should be installed between the
filter and equipment being protected.
2. The upstream pipe work must be clear of accumulated
dirt and liquids.
3. Select a filter location as close as possible to the
equipment being protected and upstream of any pressure
regulator.
4. Install filter so that air flows in the direction of arrow on
body.
5. Install filter vertically with bowl drain mechanism at the
bottom. Free moisture will thus drain into the sump “quiet
zone” at the bottom of the bowl.

Operation and Service
1. To service the filter, it is not necessary to remove the unit
from the airline. Manual drain filters must be drained
regularly before the separated moisture and oil reaches
the bottom of the lower baffle.
2. The particulate Filter Element should be removed and
replaced when pressure differential across the filter is
10 PSIG.
3. Shut off air supply and depressurize the unit, before
servicing.
4. Carefully remove Bowl by turning counterclockwise.
5. Remove Filter Element Retainer and Deflector.
6. Wipe parts, clean with soapy water or denatured alcohol
but do not use denatured alcohol on plastic bowl or
sight gauge
. If using compressed air to blow dry, be sure
to wear appropriate eye protection.
7. Install new Filter Element onto Retainer. Install Deflector
onto retainer and reinstall into Filter Body. Install Bowl
hand tight.
8. After servicing, apply system pressure and check for air
leaks. If leakage occurs,
Do Not Operate
— conduct
servicing again.
