Posted by Jacqui Blanton on Dec 6th 2013

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:
