Description

Pall’s BOS filter bags are designed to support a wide variety of high-purity applications that need absolute filtration.

 

The seamless construction of the BOS bags means no liquid bypass and the unique material composition and construction offers high efficiency with graded pore-size distribution for absolute filtration.

 

BOS seamless filter bags (filter socks) are made from thermally bonded microfibers that have high tensile strength. They provide superior resistance to channeling, unloading, bypass, and other forms of traditional leakage that result from pulsating water.

 

Why Choose Pall’s BOS FSI Filter Bags? 

 

  • Absolute rated (98%) 3-100 microns for the highest efficiency and consistent quality
  • Precise particle retention
  • Seamless construction provides the unequaled benefit of eliminating fluid bypass
  • Continuous filament structure ensures no short fibers
  • Microfiber-graded pore design offers a lower initial pressure drop
  • Thermally-bonded microfibers contain no sizing, bonding adhesive, resin or silicone
  • Pure, oil-adsorbent fibers
  • Fast rinse-in to 18 MEGOHM, low TOC content, and non-foaming
  • Can be incinerated for easy waste disposal
