Pentair Genuine OEM FNS Plus Element Assembly Complete, 48 Sq Ft

The Pentair 59023400 is the complete element grid assembly for the FNS Plus 48 sq ft DE filter, model FNSP48. It is the genuine Pentair part, and it replaces the entire grid set in one go.

Why the whole assembly

DE grids wear together. When one has torn fabric or a blinded coat, the rest are usually not far behind, and swapping the complete assembly puts 48 sq ft of fresh filter area back in the tank without piecing grids onto an old set.

Before you order

Confirm the filter is the 48 sq ft FNS Plus. The assembly ships in a box 18.75 in. long, 19.0 in. wide and 30.5 in. high. The tank o-ring is not included; the 20-7/8 in. ID o-ring for this tank is listed separately.
