Dualglass media employs a graded density fiber matrix throughout the thickness of the media. The decreasing pore size yields maximum particulate capacity by utilizing the media’s entire depth. The synergy of the Dualglass. media pack, delivers the high efficiencies required to meet and maintain target cleanliness levels without sacraficing capacity or restricing flow. Support mesh assures media integrity and pleat spacing even under dynamic flow conditions. These elements are tested to perform under the most challenging industrial and mobile applications.



  • Cleanliness range –  beta1> = 200 to beta 60 >=200
  • Temperature range – -45 F to 225 F (Nitrile seals), -20F to 250F (Viton seals)
  • Collapse pressure range – up to 3000 psid
  • Element size range – 5 gpm to 300 gpm


  • Fluid Capability – (ISO 2943) high water based fluids, petrolium fluids, water gycols, oil-water emulslions.  Viton seals required for phosphate esters, diesters, and specified synthetics.
