Guide to Diagnosing and Resolving Issues with Your Air Compressor

Air compressors serve as the backbone of numerous manufacturing and industrial procedures, and malfunctions can lead to expensive operational disruptions. Therefore, having a firm grasp of typical air compressor issues, along with quick-fix techniques, is vital to reducing this disruption time.

If you're grappling with problems related to your stationary Atlas Copco air compressor, a trustworthy air compressor diagnostic manual is what you require to restore its functionality.

This article aims to equip you with professional advice and strategies for diagnosing issues. We'll discuss everything from low-pressure anomalies to odd sounds, outlining the most frequently faced challenges, and providing practical solutions to bring your compressor back to its peak performance.

Air Compressor Troubleshooting

Here are some quick tips and focus points to help you diagnose and fix the problem:

  1. Check the power supply: Make sure that your air compressor is properly connected to a power source and that the circuit breaker hasn't tripped.
  2. Check the air filter: A clogged air filter can reduce the efficiency of your compressor and cause it to overheat. Make sure to replace the air filter regularly as per described maintenance interval.
  3. Check the oil level: Low oil levels can cause the compressor to overheat or seize up. Make sure to check and top up the oil levels regularly.
  4. Check the pressure settings:Incorrect pressure settings can cause the compressor to run all the time or not start at all at the desired pressure. Check the instruction book on how to set the correct pressure settings for your machine.
  5. Check the valves and hoses: Leaking valves or hoses can cause your compressor to lose pressure or not work at all. Inspect and repair any leaks in your compressed air network. For internal leakages on the compressor itself contact your local Atlas Copco representative. An AIRScan by an Atlas Copco expert can detect leaks in your compressed air network and propose a solution to fix them.
  6. Consult the manual: Always consult the instruction manual for additional troubleshooting tips to help you identify the root cause of the problem. Or login to SMARTLINK and find troubleshooting advice on your specific air compressor.
