① Scheduled Servicing
First maintenance: Conduct after 200 hours of operation.
Routine intervals: Perform oil/filter changes every 2,000–3,000 hours, and overhaul key components (e.g., seals, bearings) every 2 years.
② Cooling System Care
Clean air/oil coolers quarterly using non-flammable solvents—never open flames.
Inspect fan blades for dust buildup, which can reduce efficiency by 15–20%.
③ Moisture Management
Install automatic drain valves on tanks and dryers to minimize manual intervention.
For humid environments, pair compressors with refrigerated or desiccant dryers to achieve ISO 8573-1 Class 4 air quality (pressure dew point ≤3°C).
④ Safety Compliance
Test pressure relief valves annually at 1.5x working pressure (e.g., 10.5 bar for a 7-bar system).
Store oil-free compressors in dust-free areas above 0°C to prevent lubricant degradation.
⑤ Efficiency Upgrades
Retrofit fixed-speed units with variable frequency drives (VFDs) to reduce energy costs by 20–30%.
Use IoT-enabled monitors (e.g., pressure sensors, vibration analyzers) for predictive maintenance alerts.
