3M Micro-Klean G78F21N Grooved Resin Bonded 25 mic

The exclusive 3M manufacturing process produces a rigid, resin bonded, graded density structure that eliminates by-pass and the unloading characteristics of soft and easily deformable, competitive filter cartridges such as spiral wound, melt-blown, and string wound cartridges. Micro-Klean III 2-5/8" x 9-3/4" filter cartridges are the product of continuous refinement of manufacturing and fiber technologies.  The grooving of the outer surface significantly increases the filter's effective surface area, and increases the contaminant holding capacity. The design of Micro-Klean III G78F21N combines the principles of surface and depth filtration in one cartridge resulting in enhanced filter life, particle removal efficiency and optimum flow characteristics.

  • Consistent particle removal efficiencies with sharp cut-offs
  • Extended cartridge life
  • Ability to withstand high temperatures and elevated differential pressures
  • Broad chemical compatibility
  • Consistent batch to batch filtration characteristics.
