WARNING

!

To avoid unpredictable system behavior that can cause personal injury
and property damage:

• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.

• Disconnect air supply and depressurize all air lines connected to
this product before installation, servicing, or conversion.

• Operate within the manufacturer’s specified pressure, temperature,
and other conditions listed in these instructions.

• Medium must be moisture-free if ambient temperature is below
freezing.

• Service according to procedures listed in these instructions.

• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.

• After installation, servicing, or conversion, air and electrical supplies
(when necessary) should be connected and the product tested for
proper function and leakage. If audible leakage is present, or the
product does not operate properly, do not put into use.

• Warnings and specifications on the product should not be covered
by paint, etc. If masking is not possible, contact your local
representative for replacement labels.

Introduction:

Follow these instructions when installing, operating, or servicing
the product.

Application Limits

These products are intended for use in general purpose
compressed air systems only.

Adsorber Filters are not effective on: Carbon monoxide, carbon
dioxide, methane, ethane, ethylene or hydrogen. For a complete
list of vapors that can and cannot be adsorbed effectively by
activated carbon adsorbers consult the factory.

CAUTION

Polycarbonate bowls, being transparent and tough, are ideal for use with
Filters and Lubricators. They are suitable for use in normal industrial
environments, but should not be located in areas where they could be
subjected to direct sunlight, an impact blow, nor temperatures outside of the
rated range. As with most plastics, some chemicals can cause damage.
Polycarbonate bowls should not be exposed to chlorinated hydrocarbons,
ketones, esters and certain alcohols. They should not be used in air systems
where compressors are lubricated with fire-resistant fluids such as phosphate
ester and di-ester types.

Metal bowls are recommended where ambient and/or media conditions are
not compatible with polycarbonate bowls. Metal bowls resist the action of
most such solvents, but should not be used where strong acids or bases are
present or in salt laden atmospheres. Consult the factory for specific
recommendations where these conditions exist.

TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER
ONLY! DO NOT use cleansing agents such as acetone, benzene, carbon

tetrachloride, gasoline, toluene, etc., which are damaging to this plastic.

Bowl guards are recommended for added protection of polycarbonate bowls
where chemical attack may occur.

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.

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.

Inspect for nicks, scratches, and surface imperfections.
If present, reduced service life is probable and future
replacement should be planned.

Clean with lint-free cloth.

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

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.
