High-Capacity Filter Bags
Felt Bags-Standard Grade
Felt construction is generally chosen where smaller particle retention is required, in the nominal 1 to 100-micron range. It offers higher solids loading capacity than mesh. General-purpose felt bags are offered in polyester and polypropylene materials. Special-purpose felt bags are offered in polyester and polypropylene materials. Special-purpose felt bags include high-temperature service (to 500°F) bags of Nomex® nylon or Teflon®.
Felt Bag Finishes and Covers
Standard finish. Plain, as manufactured, without treatment or covers.
Glazed finish. The outermost surface fibers are melted by a momentary application of high heat. This bonds the fibers together and reduces the possibility of fiber migration.
Mesh covers completely encase the felt bag. This cover acts to contain any fibers that may separate from the filter bag. Materials available in mono and multifilament mesh, spun bonded nylon, and polyester.
