Product Overview

The Pentair 154578 strainer air relief tube component is an internal filter accessory used in Triton fiberglass sand filter systems. Installed on the air relief tube inside the filter tank, the strainer allows air to escape from the system while preventing debris or sand from entering the air relief pathway. This helps maintain correct filter pressure and ensures proper operation of the filtration system.

Constructed with a molded rubber base and metal mesh screen, the strainer is designed to withstand continuous exposure to water, filtration pressure, and pool chemicals. It is commonly used in Triton II, Triton C, and Triton C-3 filters including TR100C and TR140C models. Replacing a damaged or missing air relief strainer helps maintain efficient filtration and prevents debris from entering internal air relief tubing.
