Pentair Filter Template | FNS Plus | 98725800

Description

The Pentair Filter Template (98725800) is the OEM replacement template for the FNS Plus series D.E. filters, sized at 11-3/4 inches by 11-3/4 inches.

The filter template sits within the FNS Plus filter housing and provides the structural grid pattern that holds the D.E. filter grids in proper alignment during filtration. A damaged or warped template can cause grids to shift, leading to uneven D.E. coating and reduced filtration performance.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Poolaroo Pro Tip

When replacing the filter template, take the opportunity to inspect all D.E. grids for tears or broken fingers. A new template installed alongside damaged grids will not restore full filtration performance. Rinse the filter housing thoroughly before reinstalling to ensure no debris interferes with the template seating flush against the manifold.
