Midwest Filter Corporation
Filter Bags
Filter bags are available from 1 to 1500 microns to suit your applications. Standard
felt bag materials include polypropylene, polyester, nylon, nomex, or absolute
rated polypropylene micro-fiber material. Mesh bags are constructed of
nylon monofilament, polypropylene monofilament, or polyester multi-filament
material.
For high purity applications we offer FDA compliant
PolyMicro® BOS series bags which have seamless construction, graded
density media, and the patented Polyloc ® ring which provides a hermetic
seal between bag and housing. In addition to edible oils and other food
and pharmaceutical applications BOS bags are also ideal for use in semiconductor
and cosmetics manufacturing.
