DEX2420MAR2-Style Manual Air Relief Valve Assembly Compatible with Pro Grid DE & SwimClear Cartridge Filters

DEX2420MAR2-Style Air Relief Valve Assembly Replacement

The air relief valve assembly DEX2420MAR2-style is designed to release trapped air from pool filter tanks safely and manually. This manual air relief valve helps maintain stable pressure inside the filter. It supports smooth water flow and protects your filtration system from air buildup.

This valve assembly works with Hayward Pro Grid vertical DE filters and SwimClear cartridge filter systems. It is a direct-fit replacement that restores proper filter performance and improves system safety.

Reliable Manual Air Release Function

The Hayward manual air relief valve allows users to release excess air before starting the system. Removing trapped air helps prevent pressure spikes and uneven filtration. This improves filter efficiency and extends equipment life.

The design matches the original Hayward air relief assembly, making it suitable for routine maintenance or full replacement.

Complete Assembly With All Required Gaskets

This air relief valve assembly includes all required fittings and extra-large gaskets. No additional parts are needed for installation. The included seals ensure a tight, leak-free fit on compatible filter tanks.

Everything is pre-matched for quick setup and long-term use.
