Hayward DEX2400CR – Flex Air Relief Assembly

Product Overview

The Hayward DEX2400CR Flex Air Relief Assembly is a replacement air-relief component designed for use with Hayward vertical grid D.E. filters. It allows trapped air to escape the filter tank safely and helps prevent air build-up that can reduce filtration performance or introduce back-wash bypasses.

Key Features

• Designed for vertical grid D.E. filters—micro-clear and Pro-Grid series.
• Flexible tube with screened end to allow consistent air release while preventing d.e. escape.
• Includes hose clamp and mesh screen/sock to maintain element integrity.
• Simple, reliable design improving system performance and reducing potential for air-locked filter tanks.

Technical Specifications

• Part Number: DEX2400CR
• Application: Flex air relief for compatible vertical grid D.E. filters
• Includes: Relief tube assembly, mesh sock, hose clamp
• Weight: Approx. 0.25 lb (lightweight replacement component)

Compatibility & Fitment

This assembly fits vertical grid D.E. filter models such as the Pro-Grid DE2420, DE3620, DE4820, DE6020, DE7220, and associated Micro-Clear models that use the same manifold configuration. Always confirm your filter model and existing air-relief component before ordering.

Installation Instructions

• Shut off pump and relieve system pressure before servicing the filter.
• Open the filter lid and locate the existing air-relief tube/assembly within the top manifold.
• Remove the existing tube and screen, clean the seating area, and install the new DEX2400CR assembly ensuring the mesh sock covers the intake end.
• Secure the hose clamp snugly, replace the lid, restore pump flow and monitor for air release and proper pressure recovery.

Troubleshooting & Tips

• No air release from tube: Verify the mesh sock is not clogged or obstructed; ensure the tube is not collapsed or kinked.
• Excessive air in tank or pressure instability: Check that the relief tube is correctly positioned and fully seated; replace if damaged or deformed.
• D.E. escaping from tube end: Ensure the mesh sock is intact and secured; replace the sock if torn or missing.

Maintenance Tip

Inspect the air relief assembly annually when performing filter service. Clean the mesh sock and inspect the tube for deformation or chemical damage. Replacing this component at the first sign of wear helps maintain optimal filter function and protects the equipment from air-lock and start-up issues.
