OEM Pentair 172855 Air Vent Strainer is a stainless steel 3/4-inch component that supports uninterrupted air relief in Nautilus Plus and FNS series D.E. filters. Specifically designed to prevent debris from entering the air valve tube, this strainer safeguards internal filtration components and maintains balanced system pressure. Its robust stainless steel construction offers chemical resistance and durability for continuous use in demanding pool or spa systems. With OEM-grade precision, this part fits seamlessly into existing filter setups and is easily installed during routine service or component replacement.

Highlights

  • 3/4-Inch Stainless Steel Body: Manufactured to withstand harsh pool chemicals and outdoor conditions while maintaining structural integrity and airflow function.

  • Air Valve Protection: Blocks debris from entering the air relief line, reducing the risk of clogs, operational inefficiencies, or damage to pressure-sensitive filter components.

  • Supports Filter Efficiency: Helps regulate proper air pressure in the filter tank by maintaining a debris-free vent, contributing to optimal flow and reduced pressure fluctuations.

  • Engineered for Easy Integration: As a direct OEM match for Pentair Nautilus Plus and FNS models, it simplifies repair work and ensures dependable long-term use.

  • Small Part, Big Impact: Critical to preventing mechanical strain and ensuring that your pool or spa system continues to operate at maximum efficiency.
