Felt Bags

 

At Pure Process, we start with the finest material possible. FSI produces the felt material used in our felt filter bags in-house, guaranteeing the highest quality. Our extended life filter bags provide superior filtration of all sized particles over traditional filter bags and have 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. Through FSI we can also offer polyester inserted felts. These inserted felts include a reinforcing scrim needle inside the felt material to provide added strength and durability.
