Years of experience give us an advantage over our competitors, and our felt filter bags show it. Integrated technology and superior control over our manufacturing and quality leads to consistent performance. We start with the finest material possible. FSI produces the felt material used in our felt filter bags in-house, guaranteeing the highest quality. Extended Life filter bags provide superior filtration of all sized particles over traditional filter bags, as well as up to twice the dirt holding capacity of a standard filter bag.

Our no-bypass welded seams eliminate the possibility of fluid bypass through needle holes. We provide a variety of glazed and singed finishes to inhibit fiber migration. FSI also offers polyester inserted felts. These inserted felts include a reinforcing scrim needled inside the felt material to provide added strength and durability.

Suita felt filter bags are constructed of quality neddle felts. Needle felt provides an excellent depth filtration and high solid loading capacity. Over ten years' of experience in making bags help us choose the excellent felts with different micron ratings to suit customers' specific filtration processes.
