Air Compressor Maintenance Checklist: Important Considerations
Regular air compressor preventative maintenance is crucial for ensuring operational efficiency and longevity. An air compressor maintenance checklist serves as a comprehensive guide to inspecting and maintaining various types of compressors, highlighting key areas that need attention. A maintenance checklist helps to identify potential issues before they escalate, ensuring your facility’s compressed air system operates at peak performance, thus reducing annual energy costs and downtime.
If completing your own PM service, it is very important to check your user manual for your specific make and model of equipment. The downloadable maintenance checklists below are meant as general guides only and do not supersede your manufacturer’s recommendations. Also, remember that your usage patterns and operating environment will impact maintenance requirements for compressed air equipment. In between PMs, there are also routine maintenance tasks to be completed daily, weekly and monthly.
