Description

The Pentair FNS Plus Filter 48 sq ft (SKU EC-180008) is designed for residential in-ground pool systems where clarity, efficient filtration, and easier service are important. With 48 square feet of D.E. grid area and flow capability around 96 GPM, it handles a broad range of pool sizes and turnover demands. The robust tank construction resists chemicals and UV exposure. The curved grid pack enhances surface area while minimizing restrictions, and the backwash and air relief features reduce downtime. For pool owners seeking a strong D.E. filtration solution with longevity and ease, the EC-180008 is an excellent choice.

Pro Tip

Match your pump output and plumbing so system flow remains at or below ~96 GPM. Ensure at least ~74″ vertical clearance above the filter for grid removal and maintenance. When the pressure gauge rises ~10 psi above the start point, backwash and inspect the grid pack for wear and performance issues.
