Pentair Purex DE Grid [840] [33" x 7-1/2"] [8 Required] (72975) is a replacement DE filter component for compatible Pentair or Purex-style diatomaceous earth filter systems. DE gri ds and grid kits are used inside the filter tank to support the DE coating that captures fine debris from pool water. When grids become torn, crushed, brittle, or heavily fouled, the filter can lose efficiency, return DE to the pool, or develop poor circulation. Replacing the correct grid or kit helps restore the internal filtration structure and can improve overall filter performance after cleaning alone is no longer enough.Because many DE filters use multiple grids of specific lengths and widths, it is important to match the model, dimensions, and required quantity before ordering. Inspect the manifold, air relief, standpipe, and tank internals while the filter is open to make sure the full assembly is service-ready. Replacement DE filter part for compatible Pentair/Purex applications. Helps support proper DE coating and fine-particle filtration. Recommended when grids are torn, collapsed, clogged, or brittle. Verify filter model, grid size, and required quantity before ordering. Part number/reference: 72975. Show more
