Description
Introducing the Filbur Rectangular Diatomaceous Earth (DE) Grid, sized 18" x 11" with Center Port (FC-9825). Built for serious pool and spa filtration, this OEM-grade DE grid delivers enduring performance, precise filtration, and easy maintenance in salt and chemically-treated environments.
Why this DE grid stands out
- Extruded PVC center cores provide the strongest, most even distribution of stress. Round holes help prevent crack or collapse under heavy debris loading, keeping filtration steady even in demanding runs.
- Reinforced center cores enhance debris loading capacity and pressure differential, reducing the frequency of cleanings and maintaining higher flow rates over time.
- Premium filter media uses durable polyester that resists wear and maintains cleanliness, supporting longer filter life and clearer water.
- Sharp pleat folds with a unique synthetic fiber design prevent bridging, ensuring dirt penetrates deep into the pleats for consistent flow and easier cleaning across the entire grid surface.
- Antimicrobial end caps—reinforced for strength—treated to repel odor-causing bacteria and mold. The formulation also resists deterioration from salt pools and high chlorine levels, extending component life.
- Wider, break-resistant bands keep pleats evenly spaced, reducing flutter and maintaining optimum flow even in turbulent housing conditions.
- End caps with integrated fittings simplify installation and removal, eliminating the need for PAD adapters that can impede flow and filtration efficiency.
- Embossed part numbers make identification and re-ordering straightforward, ensuring you replace the exact grid when needed.
Perfect for demanding setups
- Ideal for saltwater pools and high-chlorine environments where filter media and seals face harsher chemical exposure.
- Fits standard rectangular DE filter housings that require an 18" x 11" grid with center port, delivering reliable fit and dependable filtration performance.
- Designed for both pool and spa filtration needs, especially where debris load is high or water clarity is a priority.
What problems does this Filbur DE grid solve?
- Prevents premature grid failure under heavy debris loading thanks to reinforced cores and stronger end caps.
- Maintains consistent water clarity by promoting deeper dirt penetration into pleats, reducing channeling and bypass.
- Minimizes maintenance downtime with longer intervals between cleanings due to improved debris loading capacity and flow stability.
- Offers straightforward installation and re-ordering, reducing downtime and confusion for service technicians and pool owners alike.
Choose the Filbur Rectangular DE Grid FC-9825 for a dependable, OEM-grade filtration upgrade that prioritizes durability, filtration efficiency, and ease of use. It’s a thoughtful investment for anyone maintaining a pool or spa that demands clear water, reliable performance, and long-lasting components.
