Synthetic Fibers Standard Or Customized NeedleFelt Filter Bag With Micron Rated 1-200um For Depth Filtration
Felt filter bags are manufactured from needle felt material in polypropylene and polyester that provide the most economic value and reliable choice for a wide range of filtration applications. By means of a depth filtration mechanism, particles penetrate and are captured throughout the depth of the filter media.
They are available in the range of 1 – 200 microns with a nominal (60-70%) efficiency.
Polypropylene and polyester are the most widely used, and have a calendered or singed external surface finish to eliminate fibers migration into the filtrate. Filter bags are available in traditional stitched form or with a fully welded construction and are fitted with a comprehensive choice of rings.
7” or 4” galvanized Steel rings (or stainless steel) which fit universally into all filter housings. Polypropylene rings and stainless-steel bands are also available.
