3M™ ME Series ASME Code Housings for 3M™ DF Series Elements and Bag Filters
The compact design of the 3M™ ME series bag housings and
in-line bottom inlet and outlet connections offer tremendous
exibility for installation and operation. The swing bolt closure
design and davit arm operation allow for easy lter element
change-out.
3M ME series bag housings come standard with a swing bolt
cover closure and davit arm for ease of cover opening. An
optional quick open/close (QOC) cover closure version is also
available. Through the use of a band clamp and hinged cover,
the QOC design allows for rapid vessel opening and closing with
minimum labor requirements. This can be of signicant benet
for operations requiring frequent lter change-outs. For more
information on the QOC design, please refer to 3M Purication
Literature LITHSHQC1.
3M Purication Inc. offers the 3M™ ME series bag housings,
for use with 3M™ DF series lter elements or conventional
bag lters, in 3, 4, 6, 8, and 12 lter element congurations.
Constructed with carbon steel, 304, or 316L Stainless Steel,
the housings are designed for use with #2 size lter bags or
elements. The housings have been engineered for maximum ow
throughput for a given vessel footprint to minimize the required
oor space. All ME series bag housings include stainless steel
baskets, for either 3M DF series element or bag lter support. The
housings are rated for operation up to 150 psi @ 300 °F and are
manufactured in accordance with ASME code and “U” stamped.

* Values represent maximum aqueous flow rates for ME series bag housings (without filter elements in stalled) yielding housing pressure drop of 3 psid. When determining vessel flow rates, the
type of filter element to be used needs to be taken into account. The total filtration system pressure drop is the sum of the housing and filter element pressure drops. For some models, larger
inlet/outlet connection sizes are avail able providing lower vessel pressure drops at higher flow rates.
