External Inspection
- Examine the vent's exterior opening for debris such as dust, dirt, or accumulated grime that may clog the outer ports
- Use a soft brush or compressed air (applied gently to avoid damaging parts) to clear any visible obstructions
- Ensure the airflow path through the outer grille or openings is fully unobstructed
Connection Check
- Check the vent's connection to the enclosure or system it serves
- Inspect the sealing interface for signs of misplacement, damage to gaskets, or gaps
- Adjust the vent's position if needed, and verify that any mounting components are intact and properly seated
Internal Examination
- Carefully disassemble the vent following manufacturer guidelines
- Inspect the core membrane for tears, stiffness, or oil/dust buildup
- If the membrane is compromised, replace it with a compatible part
- Ensure the new membrane is installed without folds or tension that could restrict airflow
Testing & Verification
- Test the vent after each adjustment or repair to confirm airflow is restored
- Connect the vent to a test system or simulate its working environment
- Check for consistent air release
- Verify that the vent is compatible with the system's pressure requirements
