Description

The Pentair 2-3/8" Automatic Air Relief Assembly is a critical component designed to remove trapped air from your pool filter system. By allowing air to vent during operation, it helps maintain stable internal pressure and ensures consistent water flow through the filter media.

Built for durability, the unit withstands exposure to pool chemicals and continuous system pressure, making it a reliable replacement for worn or malfunctioning air relief assemblies.
