Our low cost and efficient FSI™ filter bags (filter socks) come in a variety of materials, styles, sizes, and a wide assortment of collar and ring types that ensure compatibility with nearly all bag vessels in the market.
We supply a variety of glazed and singed finishes to inhibit fiber migration and the no-bypass welded seams eliminate the possibility of fluid bypass through needle holes.
We also offer polyester inserted felts, which includes a reinforcing scrim needled inside the felt material that provides added strength and durability, when a restrainer basket is not being used.

Why use a Liquid Bag Filter?
Liquid Bag Filters are a popular and common low-cost filtration solution across multiple industries including:
- General Industrial
- Oil & Gas
- Chemical & Polymer
- Food & Beverage,
- Process Water or Waste Water
- Microelectronic coatings
- & More
Liquid filter bags are usually considered where coarse pre-filtration is required upstream in a process before fine and polishing filtration.
In applications with high solids loading, filter bags can be implemented in a staged filtration approach to progressively remove the solids and ensure protection of equipment and clean process fluid.
