DESIGN FEATURES:
construction
The Catch-All shell utilizes an exclu-
sive filter-within-a-filter construction.
The new internal assembly, when used
with Sporlan molded cores, provides
maximum water capacity, excellent acid
removal characteristics, the ability to
remove products of lubricant decom-
position, and outstanding filtration. The
optional replaceable secondary filter
offers unsurpassed filtration efficiencies
without compromising the Catch-All’s
ability to hold a large amount of foreign
material. The assembly is designed so
the cores remove larger sized particles
while the secondary filter removes micro-
scopic particles. This unique construction
aggressively filters particles circulating in
a refrigerant system. This design is expe-
cially advantageous when commission-
ing a larger system.
fleXiBilitY
The shell design offers flexibility. The
new internal assembly can be used with
or without the secondary filter. The type
of filtration needed depends upon the
system requirements or application.
Using the assembly without the second-
ary filter offers the same time tested,
field-proven, filtration characteristics
expected in a Catch-All Filter-Drier.
internal asseMBlY
The internal construction is designed to
improve ease of assembly. The molded
cores simply slide over the center tube,
followed by spacer plates (if applicable).
The outlet plate is fastened to the assem-
bly by a wing screw. With the addition of
a spring, the resulting assembly is easy to
install and remove.
The seal gasket prevents solid con-
taminants from bypassing the filter. The
assembly is held tight against the gasket
by a spring. O-rings are used with the
secondary filter to provide a tight seal.
The internal parts are plated steel – no
plastic parts.
Replaceable Core Type
Bolt and nut attachMent
The bolt and nut attachment of the
endplate allows for simple, trouble-free
installation. The nuts lock against the side
of the shell for ease in tightening. Other
designs, using cap screws threaded into
the flange ring, run the risk of
twisting off
the head of the screw making removal
difficult.
fittings
Copper fittings
are excellent for fast
easy soldering.
Fittings are pre-sized for
proper fit, and suitable for use with soft
solder, silver solder, Sil-Fos, or Phos-
Copper. The fittings are brazed to the
shell with a high temperature brazing
alloy so they never loosen during the
brazing operation on the job.
A complete line of fitting sizes are avail-
able with solder connections from 1/2” to
4-1/8” ODF and pipe connections from
1/2” to 2”.
shells
Heavy steel shells provide high bursting
strength and are listed by Underwriters
Laboratories Inc. The shell exterior uses
an epoxy powder coating to prevent
corrosion even under the most adverse
conditions.
The construction illustrated is used on the C-480 through C-19200 Series Catch-All Filter-Driers (ODF Solder models only).
The C-R420, C-30000, and C-40000 Series models differ in construction, but maintain the field-proven features that have
been used successfully for many years.
