About This Item
The Hayward Air Relief Assembly (DEX2400S) is the OEM replacement air relief assembly for Hayward ProSeries side-mount sand filters.
The air relief assembly vents trapped air from the filter tank, allowing the system to reach proper operating pressure and maintain consistent water flow through the filter media. Releasing accumulated air is a routine part of filter startup and backwash cycles.

Poolaroo Pro Tip
Before removing the existing air relief assembly, ensure the filter system is shut down and tank pressure has been fully relieved. Inspect the assembly's O-ring and any sealing surfaces when fitting the replacement — a worn seal at this location is a common source of minor drips around the valve body.
