  • StrataDensity filters are constructed with AAF manufactured premium grade fiberglass media
  • The media is coated with a light adhesive to increase the amount of dirt the filters can hold
  • The double skinned media design eliminates the need for scrim or metal retainers by building the strength requirements into the fiberglass
  • Compression-resistant glass fibers decrease media pad deterioration allowing a normal rise in resistance as the filter collects dirt particles
  • A continuous adhesive bond between the media pad and chipboard frame maximizes construction strength to reduce handling damage and permit longer storage life
