Description

Our trade-size felt media strainer bags operate on the principle of depth filtration, resulting in superior dirt-holding capacity compared to woven bags.

  • Can retain both gelatinous and non-deformable solids
  • Effective capture of lightweight particles
  • While disposable, these bags can also provide limited reusability with backflushing
  • Inexpensive even for ratings 25 microns and below
  • Sewn seams standard (contact us for welded seams)

Sizes

  • #1 (P1) – 7.06″ dia. x 16.5″ length
  • #2 (P2) – 7.06″ dia. x 32.0″ length
  • #3 (P3) – 4.12″ dia. x 8.0″ length
  • #4 (P4) – 4.12″ dia. x 14.0″ length
  • Contact us for custom shapes and sizes or for industry-standard sizes not listed here
