Built to outlast standard cartridges, this model is designed to keep water clearer, longer, even in demanding saltwater or high-chlorine environments.
Why FC-2365 stands apart
- Reinforced center cores provide even stress distribution and higher debris loading, preventing cartridge collapse under heavy filtration Duty and increasing the interval between cleanings.
- Premium polyester media delivers durable, reliable filtration with cleaner water and easier maintenance, helping you maintain optimal water clarity.
- Antimicrobial end caps are reinforced for added strength and treated to repel odor-causing bacteria and mold, extending cartridge life in challenging environments.
- Salt pool and chlorine resistance—advanced formulation resists deterioration from salt systems and elevated chlorine levels, so you don’t have to swap cartridges as often in tougher setups.
- Wider break-resistant bands keep pleats evenly spaced, ensuring consistent flow and reducing flutter in turbulent housings.
- Sharp pleat folds prevent bridging, allowing dirt to penetrate deep into the pleats for higher filtration efficiency and easier cleaning.
- Integrated fittings on end caps eliminate the need for PAD adapters, simplifying installation and preserving maximum flow right out of the box.
- Embossed part numbers make identification and re-ordering quick and straightforward for ongoing maintenance.
- Extruded PVC center cores provide the strongest, most uniform support, minimizing the risk of damage and ensuring consistent filtration performance.
