The energy cost of a compressor over its ten-year life time far outweighs the purchasing cost. Maintenance accounts for 7% of all costs, showing that it is crucial in the day-to-day running of any compressor.
The Compressed air technology overview (CTV050) guide gives an introduction to the main compressed air energy saving opportunities for businesses.
Your maintenance schedule should include regular checks on the compressor and treatment packages as well as regular servicing and major overhauls from time to time, in accordance with the manufacturer’s recommendations.
For larger systems, on-going predictive maintenance – such as vibration analysis, oil analysis and thermographic surveys – can be worthwhile, as they’ll anticipate problems before they occur.
The diagram below represents a compressor and the ‘maintenance musts’ that should be carried out on a regular basis.
Click on each of the numbers to show each maintenance check and download a list of checks that should be carried out to both a compressor and the overall compressed air system.

As well as the compressor inlet filters it is important to maintain downstream filters in the compressed air system. Blockages in these can lead to large pressure drops in the system causing production problems and increased energy costs as the compressors have to run at a higher pressure
