Complete Pentair FNS Plus DE Filter Grid Assembly

The filter grid assembly is where the DE is actually located and the dirt is trapped inside the filter. It consists of 7 large grids and a small grid held together by two tie rods going through the center along with a top manifold, an internal bleed assembly, a filter template, and a holding wheel.

The Pentair FNS Plus DE Filters come in 3 different sizes. The corresponding part numbers for the filter grid assemblies are as follows:

  • 59023500 is for the 36 sq filter, which comes with 7 large 18″ and a small 18″ grid.
