Description
The Filbur FC-9420 Diatomaceous Earth (DE) Grid is a partial-grid replacement designed specifically for Pentair and Hayward DE pool filters. Measuring 12" x 9-3/4" with a 24 sq ft filtration area, this grid delivers dependable DE distribution and sturdy support where it matters most—keeping your pool water clear and easier to maintain. Why this DE grid stands out
- Robust, extruded PVC center core: The strongest possible backbone for even stress distribution and reliable debris loading, helping prevent grid collapse during heavy filtration cycles.
- Reinforced, antimicrobial end caps: Treated to resist odor-causing bacteria and mold, with integrated fittings to simplify installation and reduce the need for adapters that can impede flow.
- Wider break-resistant bands: Designed to keep pleats evenly spaced, minimize flutter in demanding pump setups, and maintain optimum flow across the grid.
- Precise compatibility for easy replacement: Embossed part numbers and exact sizing ensure a straightforward swap for Pentair/Hayward DE systems without guesswork.
- Superior DE distribution and cleaning efficiency: The grid’s structure supports uniform DE layering, which improves filtration performance and makes backwashing more effective. Ideal use scenarios
- Replacing worn or warped DE grids in mid-to-high-use residential pools or light commercial setups that rely on Pentair or Hayward DE filters.
- Upgrading aging grids to improve water clarity, reduce debris bypass, and extend the life of downstream filter components.
- Maintaining regular DE filter performance in pools with variable chlorine or saltwater chemistry due to the grid’s robust construction. What problems this grid solves
- Avoids premature grid failure under load thanks to reinforced cores and heavy-duty bands.
- Simplifies installation with molded-in fittings, reducing setup time and potential flow-reducing adapters.
- Improves filtration efficiency by ensuring consistent DE distribution and minimizing buildup from bridging or flutter. How to get the best results
- Confirm exact fit: Match the 12" x 9-3/4" partial-grid format and 24 sq ft coverage to your current Pentair/Hayward DE filter housing.
- Handle with care during installation to preserve the integrity of the reinforced center cores and end caps.
- Pair with a regular DE maintenance routine: backwash on schedule, inspect for signs of wear, and replace the grid at the first sign of cracks or warped sections to maintain peak clarity. Filbur delivers value-driven, OEM-grade filtration components, and the FC-9420 DE grid continues that tradition with durability, reliability, and precise performance—ensuring your pool stays sparkling clean with less hassle and downtime.
