Description

The Pentair FNS Plus 36 Grid Replacement Pack (198081) delivers robust, long-lasting performance for your DE filtration system. Engineered with high-impact styrene substrates covered in multi-filament polypropylene fabric, each grid resists wear in harsh pool environments. The curved grid architecture enhances surface area, improving filtration efficiency while minimizing resistance to flow. As an OEM replacement, it guarantees seamless integration with FNS Plus 36 filters — maintain peak performance and extend system life with every replacement cycle.

Pro Tip

Replace all grid elements at once if any show wear — mixing new and old degrades performance. Pair it with a new O-ring or manifold kit to seal the system after upgrade.
