The air shower room is a critical component of cleanroom systems, designed to remove contaminants from personnel before they enter a controlled environment. Although it is often seen as just an entryway, it plays a vital role in maintaining the cleanliness and integrity of the workspace. Due to its high usage and frequent door openings, regular maintenance is essential to ensure optimal performance and longevity.
To keep the air shower functioning properly, several key maintenance steps should be followed:
1. Regularly check the equipment’s technical parameters using calibrated instruments. If any readings fall out of specification, take corrective action immediately.
2. Clean or replace the primary filter media according to the usage frequency. A clogged pre-filter can reduce airflow and affect overall efficiency.
3. If the airspeed decreases, inspect the primary filter for dirt buildup. A darkened filter indicates excessive dust accumulation, which increases resistance. In such cases, clean or replace the non-woven fabric.
4. If cleaning or replacing the pre-filter doesn’t restore proper airflow, it may indicate that the high-efficiency filter (HEPA) is clogged. In this case, the HEPA filter should be replaced.
5. When replacing the HEPA filter, carefully remove the splash plate, extract the old filter, and install a new one following the original specifications. Make sure the arrow on the HEPA filter points in the direction of airflow and that the seal is tight to prevent leaks.
6. After installation, perform a leak test using a particle counter to ensure the system meets the required standards before resuming normal operation.
7. Inspect and maintain the electrical system regularly. If any faults occur, refer to the electrical diagram for troubleshooting and repairs.
8. Ensure the door closes properly and aligns with the lock mechanism to avoid jamming or misalignment.
9. Keep the temperature around the equipment below 50°C and strictly avoid open flames, as they can damage sensitive components.
Proper maintenance of the air shower room is crucial not only for its performance but also for the quality of products manufactured in the cleanroom. Neglecting these steps can lead to contamination risks, reduced yield, and costly downtime. By following these guidelines, you can ensure a reliable and efficient air shower system that supports a clean and safe working environment.
