The S5-20 is a 20” Drop-In PolyTrix gradient density filter cartridge that reduces sediment to 5.0 microns at a maximum flow rate of 10.0 GPM.

• Applications: Drop-In style sediment filter for OptiPure FX Systems reduces suspended particles to 5.0-microns.
• PolyTrix gradient-density depth filtration reduces dirt, rust, and debris as small as 5 microns to ensure clean, clear water and protect solenoids, valves, and other fittings against wear and plugging.
• Filters out larger dirt and sediment particles to extend the life of downstream sub-micron carbon filters.
• Generates less waste; only the drop-in cartridge is replaced. No discarding of metal or plastic quick change filters.
• Replacement cartridge cost per gallon is much less than proprietary quick-change filters.
• NSF-Certified under Standard 42 as replacement cartridge in OptiPure FX series systems.
• Part No. S520 252-10120, S520 25210120
