Restore peak DE filtration performance with the Filbur FC-9350 Diatomaceous Earth (DE) Grid — a full 60 sq ft grid set designed for 30" x 11" DE filters. Built to meet the demands of busy pools, this grid is a trusted OEM-level replacement that fits widely used systems from Pentair, Hayward, Jacuzzi, and Zodiac, delivering consistent clarity season after season.
Why this grid stands out
-
Reinforced extruded PVC center cores provide even stress distribution and higher debris loading, reducing the risk of grid collapse and extending time between cleanings.
-
Antimicrobial end caps are reinforced for strength and treated to repel odor-causing bacteria and mold, helping keep your filter maintenance lower and your chlorine or salt levels stable.
-
Premium filter media uses durable polyester with sharp pleat folds that prevent dirt bridging, allowing particles to penetrate deeper into the folds for more efficient filtration and easier cleaning.
-
Wider break-resistant bands keep pleats evenly spaced, minimizing flutter and maintaining optimal flow even under heavy debris loading.
-
End caps with integrated fittings simplify installation and removal, eliminating the need for adapters that can impede flow and complicate service.
-
Embossed part numbers make it easy to identify and re-order the exact replacement when you need it, ensuring you don’t mix grids during maintenance.
-
Salt and chlorine resilience delivers lasting performance in pools using varying sanitizers, helping you keep water clear without frequent grid replacement.
