INDUSTRIAL L44
BAG HOUSINGS
L44 Single Liquid Bag Housings effectively remove dirt, pipe scale, and other substances from
process liquids. Quality construction and design assure protection for all downstream
equipment.
Unfiltered liquid enters the housing above the filter bag or strainer basket; fills the interior of
the housing; and continues through the bag or strainer basket. Solids are trapped inside the
filter bag or strainer and easily removed when the housing is serviced.
