The FrontLine Gold fiberglass media pad is used primarily in conjunction with metal pad frames. It contains industrial grade media for extra heavy dirt loading conditions. The extra high fiber content of the media provides more dirt catching surface, while its progressive density pattern prevents faceloading. Dirt loads from back to front, taking advantage of the pad's entire thickness for increased arrestance and dust holding capacity.

In this FrontLine model, each fiber intersection is solidly bonded with cured resin for superior compression strength. These bonded fibers create a barrier against dirt and improve filter performance by preventing particles from passing through the media. A heavy application of Viscosine adhesive helps further retain particles to prevent them from flowing downstream.
