Description

The Pentair 191321 full grid element is a replacement component designed to restore performance in D.E. pool filters. Measuring 13-1/8", it fits select Pentair vertical grid systems and replaces worn or damaged grids that can reduce filtration efficiency.

This full grid ensures proper distribution of D.E. powder across the filtration surface, allowing the system to capture fine particles and maintain clear, polished pool water. Replacing worn grids helps improve system efficiency and extend the life of your filter.

Installation is simple—remove the old grid and install the new one into the existing assembly. Built with durable filter fabric and a reinforced frame, this grid is designed to handle repeated cleaning cycles and long-term pool use.

Installation Tips

Shut off and depressurize the system before opening the filter. Remove the grid assembly, replace the damaged grid, and reassemble carefully. Recharge with D.E. powder before restarting.
