After around 20,000 hours or four years of operation, screw air compressors usually require major maintenance, including bearing replacement. Long-term operation leads to internal bearing wear, causing loud noise and high temperatures. These signs indicate the need for an overhaul.
[pdf] Excess heat increases maintenance frequency. Mount a thermometer in the compressor room. Increase ventilation if room temperature exceeds operating limits. Inspect and remove/vacuum loose dust from inlet filters. Frequency depends on ambient dust load. Inspect and vacuum ambient side of coolers..

Firstly, regularly replace the air filters and oil filters, keeping them clean to ensure the compressor operates smoothly. Secondly, check the quality and level of lubricating oil regularly to ensure the lubrication system functions properly, reducing wear and extending component life.
[pdf] To ensure reliable operation and extend the service life of your screw air compressor, it’s essential to implement a structured maintenance plan. This includes designated operators, regular inspections, and periodic servicing.
