Product Overview

The Pentair 192326 NSP-48 complete grid assembly is a critical internal component used in Pentair Nautilus and FNS Plus D.E. filtration systems. Installed inside the filter tank, the grid assembly supports the diatomaceous earth filtration media that traps debris and contaminants as pool water flows through the filter.

This pre-assembled grid pack includes the grids, manifold, retainer grid, rods, and air relief components required for a full replacement. The assembly is designed specifically for 48 square foot D.E. filters and typically uses 24-inch grid elements to provide the correct filtration surface area. Replacing a worn grid assembly helps restore proper filtration performance, maintain water clarity, and extend the life of the pool filtration system.
