Bowl guards are recommended for added protection of polycarbonate bowls
where chemical attack may occasionally occur.
!
WARNING
To avoid polycarbonate bowl rupture that can cause personal injury or
property damage, do not exceed bowl pressure or temperature ratings.
Polycarbonate bowls have a 150 PSIG pressure rating and a maximum
temperature rating of 125°F.
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.
WARNING
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF THE
PRODUCTS AND/OR SYSTEMS DESCRIBED HEREIN OR RELATED
ITEMS CAN CAUSE DEATH, PERSONAL INJURY AND PROPERTY
DAMAGE.
This document and other information from The Company, its subsidiaries
and authorized distributors provide product and/or system options for further
investigation by users having technical expertise. It is important that you
analyze all aspects of your application, including consequences of any failure
and review the information concerning the product or systems in the current
product catalog. Due to the variety of operating conditions and applications for
these products or systems, the user, through its own analysis and testing, is
solely responsible for making the final selection of the products and systems
and assuring that all performance, safety and warning requirements of the
application are met.
The products described herein, including without limitation, product features,
specifications, designs, availability and pricing, are subject to change by The
Company and its subsidiaries at any time without notice.

CAUTION
Polycarbonate bowls and sight domes, 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 and sight domes 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.

INSTALLATION
1. Refer to WARNINGS and CAUTIONS.
2. Purge downstream air line of oil.
3. Install the unit with the air flowing in the direction indicated by the
arrow on the body and / or the Differential Pressure Indicator.
A. PREFILTER - It is recommended that a Wilkerson “B1” Element
coalescing prefilter (particle removal down to 1.0 micron; maximum
downstream remaining oil content is 0.5 ppm/wt.) is installed to protect
the dryer from contaminants and extend the element life in the high
efficiency coalescing filter (filter“C”).
B. AIR DRYER - (Refrigerated or Desiccant). An air dryer is recommended
if water vapor condensation is a problem.
C. HIGH EFFICIENCY COALESCER FILTER - It is recommended that
a Wilkerson “C” element coalescer (particle removal down to 0.01
micron; maximum downstream remaining oil content 0.01 ppm/wt) be
installed to protect the compressed air system from oil and particulate
contamination.
D. OIL VAPOR FILTER - The Type D element filter (maximum downstream
remaining oil content 0.003 ppm/wt) is an adsorption type for removing
oil vapors, oil-associated odors, whether petroleum base or synthetic
base and nearly 100% of any remaining solid contaminants.
E. DIFFERENTIAL PRESSURE INDICATOR / GAUGE- Maximum
recommended pressure drop across coalescer filters is 7 psi (0,5
bar). This can be monitored by installing a Wilkerson DP2 differential
pressure indicator.
F. VALVE- Do not use a valve or shutoff device in conjunction with a
coalescer filter that will allow a momentary or surge pressure drop
4. The drain line connection is dependent on the type of drain that is
selected.
5. Maximum inlet pressure and operating temperature ratings are: units
with Differential Pressure Indicator, 150 psig (10,3 bar) and 150°F
(66°C); units without DP2 Differential Pressure Indicator: 300 psig
(20.7 bar)150°F (66°C).
