Filter Bags

Our Customers' Needs Come First

FSI has complete, in-house control of the production of every filter bag from fiber processing to final product, resulting in highest quality with cost savings passed directly to you. Our felt bags come in a variety of materials and a wide assortment of collar and ring types that ensure compatibility with most bag vessels on the market. And most filter bags come standard with the patented Polyloc® sealing ring that provides a complete hermetic closure and eliminates the possibility of migration.

Multiple filtration uses require multiple filter types. Extended Life designs offer longer life and fewer change-outs with twice the dirt-holding capacity of standard felt bags. Multilayer designs provide high contaminant loading and long service life. The BOS Polymicro® filter bags offer absolute-rated filtration down to three microns, and an entirely seamless design for more precise filtration. The Heavy Duty Extended Life (BOS MAX) filter bag offers greater depth filtration than conventional filter bags.
