| Compressor oil change | every 2000-4000 running hours or annually, per manufacturer's oil type |
|---|---|
| Air/oil separator element replacement | every 4000-8000 hours or per differential pressure trend |
| Intake air filter | inspect every 500 hours, replace as needed or annually |
| Safety valve testing | annually |
| Cooling water side cleaning (EWNA) | condition-based, typically annually |
| Drive belt inspection/replacement | every 2000 hours or per condition |
| Oil/air separator differential pressure | replace typically at about 1.0-1.5 bar above the clean-element reading - confirm against manufacturer's manual |
|---|---|
| Drive belt condition | per manufacturer's tension chart - renew on cracking, glazing or loss of tension |
| Airend bearing condition | assess by vibration/noise trend rather than a fixed hours figure without manufacturer's data |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Marine service air compressors are not generally subject to the same periodic survey regime as starting air compressors, but safety valves, pressure gauges and receiver certification (where a dedicated receiver is fitted) are checked at annual/renewal survey; keep oil analysis and maintenance records available.
Estimated lifetime: Airend typically rated for 40,000-80,000 hours before major overhaul/rebuild under normal marine service, heavily dependent on maintenance and duty cycle - confirm against manufacturer's documentation
