Product Overview

The Pentair 150040 air relief tube is an internal part used in Triton II TR50 and TR60 commercial sand filters. Installed inside the filter tank, the tube directs trapped air to the air relief assembly so it can be safely vented during system startup or after maintenance. This function helps the filter prime properly and maintain stable operating pressure.

Maintaining a clear air relief path is important for efficient filtration. If the tube becomes damaged, kinked, or blocked, air can accumulate inside the filter tank and cause irregular pressure readings or reduced water flow. Replacing the air relief tube restores proper venting and helps ensure reliable operation of compatible Triton II sand filter systems.
