Felt filter bags (nadelfilz Filterbeutel) replacement Pall / FSI

Van Borselen has the answer when it comes to felt filter bags. Van Borselen has nearly 100 years of experience in the world of filtration. Our felt bagfilter (beutelfilters) are suitable for applications using vessel or open filtration systems and are designed to withstand higher solid loading. Van Borselen Filters only works with trusted manufacturers, which ensure a consistent great quality performance. We only work with the best materials possible to ensure you this higher quality. No matter the size of the particles, our extended life filter bags ensure superior filtration and have twice the dirt holding capacity of the standard filter bags. Due to the welded seams in our filter bags, there is no fluid bypass possible. We provide a variety of glazed and singed finishes to inhibit fibre migration. Van Borselen Filters also offers polyester inserted felts. These inserted felts include a reinforcing scrim needled inside the felt material, to provide added strength and durability, when a restrainer basket is not being used.

Polyweld Replacement Pall / FSI:

Van Borselen Filters’ PolyWeld® filterbeutel hold a distinct advantage over all types of needle-sewn bags. There is no unfiltered liquid bypass possible, due to the welded seams that eliminate this risk. As a result, Van Borselen Filters’ PolyWeld filter bags work more efficient, due to the tighter seam, and therefore result in better yields of the desired filtrate. Also, the bags are fibre free, because of the fused edges, and therefore there is no fibre migration possible. Since these bags are not produced with thread, there is also no silicone contamination possible. The Van Borselen Filters’ PolyWeld filter bags are available in standard and extended life polypropylene or polyester felt and have the by-pass free Polyloc.

​Extended Life filter bag Pall / FSI

Van Borselen Filters Extended Life filter bags ensure the best performance possible on many different types of contaminants, like gels, particles with various shapes and particles with various sizes. The coarse, pre-filtering layer, is designed to provide long service life and captures a large amount of contaminants without excess surface loading. The POEX is able to filter twice the amount of particles as compared to standard felt bags. This results in the fact that you don’t have to change the filter bags as often as with the standard felt bags. These Extended Life filter bags are the solution in industries such as chemicals, automotive coatings, resins, edible oils and other fluids.
