Description
Meet the Filbur Rectangular Diatomaceous Earth (DE) Grid — a purpose-built replacement designed for 18" x 12-7/16" DE filter housings with a center port. Model FC-9830 brings Filbur’s OEM-grade engineering to your pool or spa, delivering dependable DE filtration with long-lasting performance you can rely on.
Engineered for durable, high-performance DE filtration
- Reinforced center spine provides even stress distribution, helping prevent grid deformation as the DE bed loads up and your filter runs through backwashes.
- Rectangular, high-surface-area grid promotes uniform Diatomaceous Earth distribution and minimizes channeling, yielding clearer water and more efficient filtration.
- Center-port integration aligns cleanly with standard DE filter manifolds, simplifying installation and reducing potential flow restrictions.
- Durable PVC construction stands up to chlorine, saltwater, and routine cleaning cycles in both pools and spas.
- Designed for long life with a robust grid that resists cracking and warping, delivering dependable performance over time.
Why this matters for you
Choosing the FC-9830 DE grid means fewer replacements, more consistent filtration, and consistently clear water. Built to Filbur’s OEM standards, it’s engineered to maintain optimal flow and filtration quality, so you spend less time on maintenance and more time enjoying your pool or spa.
Ideal use cases
- Residential pools equipped with DE filtration systems that require a precise rectangular grid replacement
- In-ground spas where stable DE distribution supports pristine, chemically balanced water
- Seasonal pool maintenance programs needing reliable, plug-and-play grid replacements that fit the original housing
How it compares to typical grids
Unlike generic grids, the Filbur FC-9830 combines a reinforced center spine with a meticulously engineered rectangular grid pattern. This design delivers more even DE distribution, reduces flow bottlenecks, and stands up to the rigors of salt and chlorine-heavy environments, providing a longer service life and more consistent water clarity.
Care and installation tips
- Power down the system and relieve pressure before replacing the grid.
- Inspect the filter housing for cracks or warping; replace any compromised components before reinstalling the grid.
- Rinse the grid thoroughly after backwashing to remove accumulated debris and prevent residual cloudiness.
- Regularly monitor water clarity and flow rate; a noticeable drop may indicate the grid needs replacement.
