Why Does Air and Oil Mist Expel from My Atlas Copco XAS 185 Air Filters After Stopping?
If you notice air and oil mist coming out of your Atlas Copco XAS 185 air compressor's filters immediately after shutting it down, it’s a sign that something isn’t working properly. Ignoring this can lead to bigger issues like excessive oil loss, contaminated filters, and costly downtime. Here’s a quick guide to help you troubleshoot and fix it.
Possible fault: Valve at element outlet
The most common cause of air and oil mist expelling from the filters after stopping is a faulty valve at the element outlet. When this valve isn’t sealing correctly, it can allow residual air and oil to escape.
Corrective actions to take
- Remove and inspect the valve at the element outlet. Replace if necessary.
- Replace the air filter elements and safety cartridges to ensure clean airflow and proper protection.
- Check the oil level and add oil if needed.
- After adding oil, run the compressor for a few minutes, then stop and recheck the oil level to confirm it’s at the correct mark.
Final thoughts
Addressing a leaking valve and refreshing your air filters helps maintain your Atlas Copco XAS 185 compressor’s efficiency and reliability. Regular maintenance not only prevents unexpected issues but also extends the life of your compressor.
