Summary

Product Identification

Type: FSI Bag Filters
Design: Felt bags designed to withstand higher solid loading, suitable for applications using vessel or open filtration systems.
Features:
- "Extended Life" filter bags provide superior filtration of stated sized particles, as well as up to twice the dirt holding capacity of a standard filter bag.
- No-bypass welded seams eliminate the possibility of fluid bypass through needle holes.
- Variety of glazed and singed finishes to inhibit fiber migration.
- Polyester inserted felts include a reinforcing scrim needled inside the felt material, to provide added strength and durability, especially when a restrainer basket is not being used.
