2.1 General Information
Description
Both Streamline and Mainstream Filters and Strainers are perfect solutions for continuous processing operations.
Mainstream filters and strainers are suitable for vertical mounting using an optional stand, wall mount brackets, or other external
means. The Streamline filters and strainers are suitable for horizontal or vertical mounting, directly into the pipe work.
Both Streamline and Mainstream filters and strainers can use a twin setup. A twin filter or strainer setup consists of two
complete units mounted onto a single stand. Directional valves at the inlet and outlet ports allow one unit to operate while the
filter media in the other unit is being changed or cleaned.
Both Mainstream and Streamline filters and strainers are available in long or short models, with standard construction of stainless
steel. All Mainstream models have side-entry ports. Streamline models have ports either at both ends (model SM or FM), or with
a side inlet, bottom discharge configuration (model SMS or FMS).
Filter Versus Strainer (Mainstream Example Used)
When used as a filter, the unit contains a basket with a disposable bag that allows you to remove undesirable particles from a
liquid or gas (down to 0.5 microns).
A strainer contains a perforated stainless steel basket, v-shaped wire basket, or wire mesh basket that allows you to remove
larger particles (from 73 microns and higher) from the process stream.
Filter/Strainer Options
Mainstream
SEF Mainstream Filter: allows filtering from 0.5 micron to 800 micron using a filter bag.
SES Mainstream Strainer: allows medium or fine straining with either a perforated metal basket (0.033 or 0.062 diameter
perforations) or a wire mesh basket with 20, 40, 60, 80, 100, 150, or 200 mesh. Suited for straining particles
down to 73 micron.
SEB Mainstream Strainer Basket: allows course straining of large particles and foreign matter using large perforations
(0.5, 0.25, 0.125, and 0.09375 diameter).
SEBHVW Mainstream Strainer Basket: allows for fine straining using a v-shaped (Vee-Wire®) basket with wire gaps of 0.005,
0.0075, 0.010, 0.015, 0.020, 0.025, 0.030, and 0.035.
Note: Minimum rating per 3A standard for Vee-Wire applications is 125 microns (0.005 gap.) Vee-Wire is a
registered trademark of U.S. Filter.
Note: 3A does not approve the use of wire mesh baskets or over screens.
Streamline
SM/FM Streamline in-line filter or strainer: allows you to strain or filter using either an overscreen or a filter sock. Suited for
coarse to medium straining ¼" to 200 mesh, or filtering 765 to 40 micron.
SMS/FMS Streamline in-line filter or strainer: allows you to strain or filter using either an overscreen or a filter sock. Suited for
coarse to medium straining ¼" to 200 mesh, or filtering 765 to 40 micron.
