154578 | Pentair Triton II and Triton C-3 Filters Air Relief Strainer | 1/4"

OEM Pentair Air Relief Strainer 154578 is a precision-designed 1/4-inch replacement part used in Pentair Triton II and Triton C-3 pool and spa sand filters. Measuring 1-1/4 inches in diameter, this component ensures proper air venting within the filtration system by allowing excess air to escape. This process maintains optimal internal pressure and prevents system strain that can occur due to trapped air. Built for durability, the strainer withstands consistent exposure to water, chemicals, and varying pressures, making it essential for efficient, safe, and long-term filtration system performance.

Highlights

• Maintains Air Relief Functionality: Allows trapped air to escape from Triton II and C-3 filters, preventing system imbalances and maintaining smooth filter operation.
