2. Install as close to the point of use as possible.

3. Unit must be installed with the flow in the direction of the flow arrow on

the body cover and with bowl down.

Avoid using reducing bushings, couplings, etc., whenever possible

to install this product. These devices restrict air flow and can affect

performance.

5. Install filter/regulator in a vertical position with bowl side down.

Maximum pressure rating is 150 psig (10.3 bar) for transparent

plastic bowls, and 250 psig (17.2 bar) for metal bowls. Temperature

range is 32°F to 125°F (0°C to 52°C) for transparent plastic bowls,

This product is supplied with two auxiliary ports located on the front and

rear faces of the body. These ports may be used as additional filtered/

regulated ports or for pressure gauges. A pipe plug is supplied to block

the unused port. Make sure pipe plug is sealed before installation.

8. To increase regulated pressure, pull adjusting knob up and turn

clockwise. To reduce pressure, turn knob counterclockwise. To lock

knob, push down.

9. To panel mount this unit the following applies:

– Model B18: Panel clearance hole diameter = 1.94" (49.3 mm).

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.

EXTRA COPIES OF THESE INSTRUCTIONS ARE AVAILABLE FOR

INCLUSION IN EQUIPMENT / MAINTENANCE MANUALS THAT UTILIZE

THESE PRODUCTS. CONTACT YOUR LOCAL REPRESENTATIVE.

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.

Do you have a question about the Wilkerson B18 and is the answer not in the manual?

This document provides installation and service instructions for Wilkerson Filter/Regulator Models B18, B28, and B28A. These devices are designed to filter compressed air and regulate its pressure, ensuring optimal performance and longevity of downstream pneumatic equipment.

Function Description:

The Wilkerson Filter/Regulator combines the functions of an air filter and a pressure regulator into a single unit. The filter removes particulate matter and moisture from the compressed air, while the regulator maintains a constant output pressure, regardless of fluctuations in the inlet pressure or changes in downstream air consumption. This dual functionality helps protect pneumatic components from contamination and ensures consistent operation.

- Clean relief seat with a soft, dry cloth.
- Reassemble in reverse order, ensuring slip ring is properly positioned and applying specified bonnet torque values.
Troubleshooting Leaks:
- Creeping Regulated Pressure: Most likely caused by contamination on the valve seat. Refer to Valve Assembly maintenance.
- Leaks from Bonnet Vent Holes: May be caused by contamination on the diaphragm relief seat, seal deterioration, or diaphragm damage. Refer to Valve Assembly and Main Spring/Diaphragm maintenance.
Model Identification (B28 vs. B28A):
- B28A models (current design since December 1997) have different internal parts and require different repair kits than B28 models.
- B28A models have "28A" permanently marked in two places on the bonnet and raised characters "28A" internally on the body (visible once the diaphragm is removed).
- Parts between B28 and B28A units are NOT interchangeable.
- If unsure, contact your local Wilkerson distributor.
