Filter Housings

3M™ DC series filter housings, constructed of durable 304L stainless steel, meet general­purpose industrial and commercial filtration needs. All wetted welded surfaces are stain­less steel. External surfaces of these filter housings are electro-polished for a consistent,
easy care finish.

The filter housings are available in a variety of sizes to accommodate from 4 to 88 filter
cartridges (Single length equivalents) with lengths to 40 inches (see Ordering Guide). The
housing handles liquids at pressures and temperatures of up to 150 psig (10.3 bar) at 250°F
(121°C), see Table 1.

Specifications

Table 1 gives standard model specifications for 3M DC series filter housings. Note that
maximum operating pressure and temperature is the rating for the
housing only. Actual housing operating temperature depends on temperature and chemical
capability of the filter cartridge and gasket used in the housing.

Cartridge Filter Housings

Cartridge Requirements

3M DC series filter housings accept both single and multiple length filter
cartridges. Table 2 lists the number of filter cartridges for each model housing.

Features & Benefits

304L stainless steel construction.

n Provides excellent corrosion protection for rugged, long-lasting service.

Accepts varying length cartridges.

n Allows use of 9¾," to 10" modular cartridges for greater flexibility.

Shouldered seal plates.

n Solid fit into cartridge core ensures positive seal and prevents bypass.

V-Band Clamp and Swing bolt designs.

n Optimizes cartridge change-out.

Removable cartridge posts.

n Easy cleaning reduces maintenance.

Housing drains located on dirty and clean chambers.

n Allows full drainage of chambers for optimized filter change-out.

Air Vent.

n Allows venting before start-up and draining for safe filter operation.

Pedestal cup fitting.

n Allows for use of both DOE or SOE cartridges.

Flow Rates

Table 3 lists the maximum water f low rates in gallons per minute (GPM) for each model
filter housing.

Use the data in Table 3 only as a guide in establishing the maximum housing flow capac­ity; do not use it for filter sizing. Once a f low rate for a selected cartridge is known, use
Table 3 to check whether the housing’s flow rate falls within the
recommended guidelines.

When sizing a filter, the amount of contaminant load needs to be considered in
addition to the flow rate and desired pressure drop. Low initial pressure drop
enhances filter cartridge life.

Cartridge Seal Assemblies

The 12DC and 22DC housings include spring seal assemblies (Picture 1) that permit the
use of filter cartridges with single length equivalents of 9 3/4 to 10 inches.

4DC and 5DC models use pressure plate assemblies while 12DC and 22DC models use
pressure plate with individual spring and seal assemblies.

Standard housings are configured to accept double open end style cartridges. To adapt the
housing to accept single open end, double o-ring cartridges with locating spear, remove
the housing cartridge posts and the spring & seal assembles. Replace the standard pres­sure plate and the center rod with the SOE pressure plate and center rod (order separately).

Standard Model Dimensions

To find a selected dimension, refer to Table 4 to locate the model in the left column and
the selected dimension symbol (A-D) in the top row. These dimensions can be used for
rough plumbing. For critical installations, request a certified drawing.
