Coalescing Filter Model M21 with
Variations and Accessories
ISSUED: February, 2006
Supersedes: August, 1995
Doc.# 83283000, ECN# 060135, Rev. 2
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 connection may be
attached to drain port if desired.
6. Maximum inlet pressure and operating temperature ratings are:
transparent plastic bowls, 150 psig (10,3 bar) and 125°F (52°C); metal
bowls, 150 psig (10,3 bar) and 150°F (66°C).
TYPICAL INSTALLATION (not to scale)
A. PREFILTER - It is recommended that a Wilkerson 5-micron-rated
prefilter be installed upstream from the coalescer filter to prolong
element life.
B. AIR DRYER - (Refrigerative or Twin Tower). An air dryer is generally
preferred for optimum results, but is optional.
C. COALESCER FILTER - Do not touch the filter element once it has
been put into service; the slightest pressure on the outer foam cover
can easily damage it once it has been used.
D. AC PAK - The Type D element 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.
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
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.

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.
