How to stop an air compressor from overheating

In winter the cold weather can cause several problems, such as the build-up of condensates inside your air compressor, but in summer the main problem you face is likely to be the question of how to stop an air compressor from overheating.

The answer can depend on the type of air compressor you have, and on where it is positioned and how it is used, and it does not necessarily mean anything is wrong with your air compressor.

Some of the ways how to stop an air compressor from overheating might need replacement air compressor parts, or it may even be better to buy a new air compressor that’s more suited to the job, while others are environmental.

For instance, if your air compressor is producing excess heat, placing it in a more ventilated area could help to solve the problem, while you may need replacement air compressor parts including new fans and unclogged filters so hot air can escape more easily from the system.

Check the compressor’s oil level, filters and separators, and replace them as required so that the oil is definitely not adding to the problem of high ambient temperatures – obviously this only applies if you have a system lubricated with oil, and will not be relevant on oil-free air compressors.

For oil-free air compressors, check the ventilation and ducting, and if it is cutting out due to excess heat, make sure it is not the high temperature sensor itself that’s at fault.

No matter what type of air compressor you have, improving the ventilation around it is a good idea, but if you can’t bring more cool air in, look at ensuring the hot air is exhausted into a different room, or ideally outside, via appropriate ducting.

And if you have gradually increased the demand on your air compressor over time, check that you’re not working it beyond its stated capacity, as this will not only cause overheating in the short term, but also shorten the lifespan of the system over the long term.

By buying a new air compressor that’s designed to handle the capacity you need from it and situating it correctly with adequate exhaust ducting and ventilation, you can create a much more carefully managed environment overall and keep your compressor running in warmer weather for longer.
