Doc.# 83212000, ECN# 060135, Rev. 3

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.

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 diester 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 occasionally occur.

Safety Guide

For more complete information on recommended application guidelines, see the
Safety Guide section of Pneumatic Division catalogs or you can download the

INSTALLATION

1. Refer to Warnings and Cautions.

2. Purge downstream air line of oil.

3. Install as close as possible to where regulated air is being used.

4. Install the unit with the air flowing in the direction indicated by the
arrow on the body.

5. A drain line with 3/8" or 10mm ID flexible tube may be attached to
drain port if desired.

6. Maxim

um inlet pressure and operating temperature ratings are:
transparent plastic bowls, 150 psig (10,3 bar) and 32°F to 125°F (0°C
to 52°C); metal bowls, 150 psig (10,3 bar) and 32°F to 150°F (0°C to
66°C).

TYPICAL INSTALLATION (not to scale)

A. PREFILTER - It is recommended that a “B” Element coalescing (0.5

ppm) prefilter be installed upstream from the coalescer filter to prolong
element life.

B. AIR DRYER - (Refrigerated or Desiccant). An air dryer is generally

preferred for optimum results, but is optional.

C. HIGH EFFICIENCY COALESCER FILTER - It is recommended that

a “C” element coalescer (.01 ppm) filter be installed to protect the
compressed air system from oil and particulate contamination.

D. OIL VAPOR FILTER - The Type D element filter (0.003 ppm) is an

adsorption type for removing oil vapors, oil-associated odors, whether
petroleum base or synthetic base, and nearly 100% of any removing
solid contaminants are removed.

E. DIFFERENTIAL PRESSuRE INDICATOR - Maximum recommended

pressure drop across coalescer filters is 7 psi (0,5 bar). This can be
monitored by installing a Wilkerson differential pressure indicator.

. VALVE - Do not use a valve or shutoff device in conjunction with a

F

coalescer filter that will allow a momentary or surge pressure drop
greater than 50 psi (3,4 bar). To avoid high surges which can either
ruin the element or momentarily allow downstream contamination,
use a slow- opening type valve.

MAINTENANCE

1. The element operates effectively when it is saturated. The element's
useful life will end only when the resistance to flow becomes too high
or the maximum permissible pressure is reached. The element cannot
be cleaned or reused and must be replaced at the end of its useful
life.

2. IF THE uNIT HAS A MANuAL DRAIN, DRAIN THE uNIT ONCE EVERY 8 HOuRS.

3. When bowl becomes dirty, replace the bowl or clean by wiping with a dry, clean
cloth.

4. Before placing the unit in service, make sure that the bowl and bowl guard are
reinstalled, and securely locked in place.
