Filter Bags

Pall's FSI™ filter bags (or filter socks) 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.

Pall’s FSI™ filter bag products provide efficiency with both low cost and use.  We supply higher solid loading, superior chemical compatibility, consistent quality, and performance supporting the fluid processing needs in a variety of Oil & Gas, Chemical, Food & Beverage, and other Industrial applications.

Description

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. 

 

Features:

 

  • Full line of felt materials and micron ratings 

  • Conventional sewn bags or the PolyWeld® welded seam bags available 

  • FSI PolyLoc® ring or other common bag rings available on most bags 

  • Heavy Duty and Extended Life designs available to suit your filtration needs.

 

If your application requires the ease-of-use of a bag filter system with the high performance of a cartridge filter, Pall's Marksman™ Series of filters may be just what you are looking for. Marksman filters provide customers with a cost-effective alternative to bag filters. Find out more about Marksman filters by visiting the links below:

Why use a Liquid Bag Filter?

 

Liquid Bag Filters are a popular and common low-cost filtration solution across multiple industries including:

  • General Industrial
  • Automotive
  • Oil & Gas
  • Refining
  • 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.
