Our Standard Felt Liquid Filter Bags are constructed using 100% synthetic fibers in polypropylene, polyester, HT (aramid), and PTFE. The proper combination of fiber diameters, weights, and thickness results in an economical and highly efficient depth filter media.
To reduce fiber migration, polypropylene bags are treated with a glazed finish, while polyester and HT bags are singed. These treatments ensure improved filtration performance, cleaner filtrate, and longer service life across a wide range of industrial applications.
