Pentair FNS Plus Grid Assembly

Yes, this is a complete kit. It comes with the seven full grids, one partial grid, the manifold, the tie rod, and the air bleed assembly, so you don't need to source individual components separately.

This assembly is engineered specifically for the Pentair FNS Plus 24 sq. ft. filter model (180006). Before purchasing, verify your filter model number on the tank label to ensure compatibility.

Replacing the entire assembly is generally more efficient and reliable. It ensures all components are new and perfectly aligned, which prevents the common issue of mismatched parts causing leaks or poor filtration performance.

This specific assembly is designed for a 24 square foot filtration area. It is critical to match this square footage to your existing filter tank, as a mismatch will prevent the assembly from fitting properly.

Installation is straightforward and typically requires only basic hand tools, such as a screwdriver or nut driver, to secure the manifold and tie rod. Ensure you have a fresh tank O-ring on hand, as it is standard practice to replace that seal whenever you open the filter housing.
