Atlas Copco XAS 185: Top Air Filter Mistakes to Avoid

Avoid These Air Filter Mistakes on Your Atlas Copco XAS 185

The air filter on your Atlas Copco XAS 185 does more than just protect your engine. It ensures efficient airflow and helps maintain pressure and cooling performance. A neglected or improperly handled air filter can cause power loss, overheating, and costly repairs. Here’s a list of common air filter mistakes and how to avoid them.

1. Ignoring the air filter service indicator

The vacuum indicator on the air filter housing lets you know when restriction levels are too high.

  • Suggested action: Check the indicator regularly. If the red band is fully visible, it means the filter is clogged and needs to be replaced. Always reset the indicator after servicing.

2. Reusing dirty filters

Cleaning and reinstalling an old filter might seem like a shortcut, but it can lead to poor sealing and reduced filtration efficiency.

  • Suggested action: Replace air filter elements with new, OEM-equivalent filters as recommended. Avoid blowing compressed air directly into the filter element. This can damage the media and let contaminants through.

3. Overlooking the dust discharge valve

The vacuator (dust discharge) valve at the bottom of the filter housing helps remove heavy particles before they reach the element.

  • Suggested action: Press the dust discharge valve periodically to release accumulated debris. Make sure it isn’t blocked or stuck closed.

4. Forgetting to check for leaks

Leaks around the air filter housing or connections can allow unfiltered air directly into the compressor and engine, causing rapid wear.

  • Suggested action: Inspect seals and gaskets whenever you service the air filter. Replace any damaged or hardened gaskets immediately to maintain proper sealing.

5. Ignoring operating environment conditions

Dusty or sandy environments drastically shorten air filter life, requiring more frequent checks and replacements.

  • Suggested action: In harsh conditions, inspect the filter daily or after each shift. Keep a spare filter element on hand to avoid unexpected downtime.

6. Skipping regular maintenance intervals

Waiting for a noticeable drop in performance before checking your air filter can lead to severe engine or compressor damage.

  • Suggested action: Follow the preventive maintenance schedule in your manual. Even if the filter looks clean, replace it at the recommended service interval to ensure consistent performance.

Final thoughts

Proper air filter maintenance keeps your Atlas Copco XAS 185 compressor performing reliably and helps extend the life of internal components. Avoiding these common mistakes saves money and prevents unexpected jobsite headaches.
