Cryspool DE Pool Filter Cartridge 48 sq ft Replacement for FNS Plus 48 / Jandy DEL/DEV 48 — Polypropylene Pleats, Durable 11×24in

Cryspool 1004 DE is a 48 sq ft diatomaceous earth replacement cartridge designed to fit FNS Plus 48 and Jandy DEL/DEV 48 systems for thorough pool filtration.

This Cryspool cartridge is built to restore or upgrade your DE filter’s performance with a high-filtration surface area and durable polypropylene pleats. Sized to match common 48-square-foot DE grid assemblies, it installs into many legacy and current pool filter housings. The cartridge aims to trap fine particles, resist wear during repeated cleanings, and extend time between replacements when maintained properly.

Will this cartridge fit my FNS Plus 48 or Jandy DEL/DEV 48 filter?

Yes — the Cryspool 1004 DE cartridge is made to match the dimensions and grid layout used by FNS Plus 48 and many Jandy DEL/DEV 48 series models. It includes the same number of full and partial grids to replicate original flow and filtration.

• Dimensions: 11" width × 24" length with 7 full grids and 1 partial grid
• Filtration area: 48 square feet, compatible geometry for DE4820 and similar housings
• Fits referenced part numbers like 59002300 and 59002400 as a replacement

How does the material and construction affect cleaning and longevity?

The cartridge uses enhanced polypropylene fiber treated for higher strength and dirt-holding capacity than standard point-bond media. That structure lets contaminants lodge deeper in the pleats and release more fully during rinsing, helping retain filtration performance over multiple cleanings.

• Advanced polypropylene pleats resist tearing during backwashing or pressure washing
• Improved dirt penetration reduces surface clogging and extends usable life
• Recommended cleaning when pressure gauge reaches the preset threshold

What maintenance steps make this cartridge last longer?

Regular inspection and timely cleaning are the best ways to maximize the cartridge’s service life. When the system pressure rises to your recommended limit, remove the cartridge and rinse the pleats thoroughly to dislodge captured debris. Allow to dry fully between deep cleans if storing spare cartridges.

• Rinse with a garden hose along the pleats to flush out trapped particles
• Use gentle brushes or approved cleaners for scale or oil buildup sparingly
• Rotate or replace cartridges according to seasonal use and water quality

What pool systems and part numbers is this compatible with?
