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