When Should an Atlas Copco Air End Be Overhauled or Replaced?
Noticing reduced airflow, rising temperatures, or abnormal noise from your compressor? These may be signs your air end is due for an overhaul or replacement.
An Atlas Copco air end should typically be overhauled every 30,000–40,000 hours and replaced around 60,000 hours, or sooner if there are signs of wear, noise, or performance loss.
The air end operates under intense pressure and heat. Over time, bearings, seals, and rotors wear down, reducing efficiency and increasing the risk of failure. Timely overhaul prevents major damage and restores performance. If the air end reaches its cycle limit or suffers internal damage, full replacement is often more cost-effective.
| Condition | Recommended Action |
|---|---|
| 30,000–40,000 hours usage | Schedule professional overhaul |
| Abnormal noise or vibration | Inspect bearings and rotor alignment |
| Oil carryover increases | Check for worn seals or rotor scoring |
| Drop in airflow or pressure | Assess internal compression efficiency |
| Metal particles in oil | Stop immediately, possible failure |
| Over 60,000 hours | Plan for full replacement |
