Cartridge Requirements
The 3M CT101, 102 and 103 series filter housings can use one,
two, or three 9¾” equivalent single-length filter cartridges,
respectively. The 3M CT102 and 103 Models can also use one
1” filter cartridge and one 29¼filter cartridge, respectively. A
shorter version of the 3M CT101, that uses a 5” double open end
cartridge, is also available.
Flow Rates
Table 2 lists the maximum recommended flow rates in Gallons
Per Minute (GPM) for the 3M CT101 and 102 Models. Use the
data on Table 2 only as a guide in establishing housing flow
capability; do not use it for filter sizing. Once you know the flow
rate for a selected cartridge, then use Table 2 to check whether the
housing's flow rates fall within the recommended guidelines.
When selecting a filter's size, make sure you consider the
amount of contaminant you want removed as well as the flow
requirements; this ensures the longest possible cartridge life.
Standard Model Specifications
Table 3 lists standard model materials of construction and
connection sizes. Table 4 lists dimensions and shipping weight.
All dimensions are nominal and can be used for determining
overall space requirements. To find a dimension, locate the model
you want in the left column of Table 4 and the selected dimension
symbol (A through C) in the top row. Where the column and row
meet is the model's dimension.
The 3M™ CT series filter housings
are three-piece, all-metal housings
with ring-nut closures. These
housings are designed to meet
general industrial filtration needs.
The 3M CT Models offer you a
choice in construction materials for
wetted surfaces and are available
with a 316 stainless steel head
with 304 stainless steel sump or in
all-316 stainless steel in one-high
(CT101), two-high (CT102), or
three-high (CT103) designs. Ring
nuts for head to sump sealing are
nickel plated brass to eliminate
potential thread galling. A ring
nut tightening tool is included. All
3M CT Model heads have tapped
mounting pads; mounting brackets
are available as an accessory.
The 3M CT Models have liquid
flow rates of up to 26 GPM, and
a maximum operating pressure and temperature of 300 psig at
200 °F. For air and gas service, 3M CT Models have a maximum
operating pressure and temperature of 180 psig at 200 °F.
Design Features/Benefits
Rugged, three-piece, all metal construction provides long
service life and quick & easy cartridge change-out.
Design flexibility: 1, 2 or 3-high cartridge models for use
with 9 ¾", 19 ½, or 29 ¼” filter cartridges.
Drilled and tapped mounting holes: Ready for mounting
bracket installation.
Options
Choice of gasket materials.
Mounting bracket available as accessory equipment.
Operating Parameters
Table 1 lists standard model operating parameters for the 3M
CT series filter housings. In Table 1, the maximum operating
pressure is the rating for the housing only. Actual filter operating
temperature is dependent on the temperature capability of the
filter cartridge.
