1/4" and 3/8" F12 Particulate and Adsorber Filter
83-953-000
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. 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. Adsorber elements are designed to adsorb vaporous
contaminates. The relative efficiency of an adsorber varies
depending on the vapor to be adsorbed and the environmental
temperature. At higher temperatures, adsorbers become less
efficient.
Adsorber elements are not particle filters. All particles and
aerosols should be removed prior to adsorbing vaporous
contaminants. The initial pressure drop across an adsorber
element (1.5 PSIG maximum) should never increase. The
presence of any liquids, aerosols or particulate matter in an
adsorber indicates that the effective life of the element has
been exceeded and the element should be replaced and the
system cleaned.
The most effective method of testing whether an element
needs to be replaced is to smell the air coming from the
adsorber. Offensive odors will be present well before oil levels
become detectable.
4. The differential pressure indicator, located on top of the filter
body, gives a visual indication of the pressure differential across
the filter element. Change the filter element when half or more of
the orange piston is above the retaining ring when air is flowing.
For units without a differential pressure indicator, pressure
differential gauges should be used to determine when the
maximum recommended pressure differential has been reached.
5. Shut off air supply and depressurize the unit before servicing.
6. After servicing, apply system pressure and check for air leaks.
If leakage occurs, Do Not Operate — conduct servicing again.
