A rectangular DE grid helps provide the filtration surface needed inside a compatible diatomaceous earth filter assembly, and this Filbur FC-9840 grid is designed in an 18 inch by 15-3/16 inch center-port format for matching applications. When a DE grid becomes damaged or less effective through normal use, the filter can lose the dependable support it should provide.
The 18 inch by 15-3/16 inch size, center-port configuration, and FC-9840 reference give this part practical value because DE components work best when the replacement matches the original grid layout and connection style closely. A properly selected grid helps restore intended filtration performance and contributes to cleaner filter maintenance.
This type of part is especially useful when the broader filter body remains serviceable and the maintenance need is centered on the internal grid itself. That keeps the repair focused and efficient.
Installed in the proper setup, this rectangular DE grid helps restore dependable filtration support and contributes to better overall system operation.
- Rectangular DE grid in an 18 inch by 15-3/16 inch format
