Technical Specifications

Part Number: CX3000J1
Application: Air tube screen / relief filter assembly for compatible cartridge filter tanks.

Installation & Compatibility Notes

Before installation, shut off the pump and relieve system pressure. Remove the filter lid and locate the air relief tube or screen housing. Extract the old screen assembly, clean the surrounding area of any debris or buildup, and install the new CX3000J1 screen. Reassemble the tank lid, restore circulation, and observe whether the air relief operates normally and that filter pressure behaves within expected ranges.

Maintenance Tips

Inspect the screen during routine filter servicing; replace if mesh is clogged or damaged.
Keep in stock as part of your filter maintenance kit—screen blockage is a frequent cause of airflow issues and increased system resistance.
Ensure that filter lid and clamp integrity are maintained to avoid leaks and bypass flow which may affect the screen’s function.

For professionals and pool-savvy homeowners alike, the CX3000J1 offers a simple, effective maintenance replacement that helps keep the filter’s air relief system operating correctly. Installing the right component reduces service calls, supports better water flow, and helps maintain system efficiency over the long run.
