What Happens if an Air Compressor Runs Out of Oil?
An air compressor requires oil lubrication, like a car engine, to minimize the friction of moving parts. If an air compressor runs out of oil, it will produce significant heat due to friction, and parts will start to expand before finally seizing the compressor. In compressors, there is a crankcase that is always filled with lubricant.
Of course, not all air compressors use oil; some are oilless. For more information visit our Oilless Air Compressors vs. Oil Compressors guide!
FAQs (Frequently Asked Questions)
If there is no lubricant oil in the oil sump of an air compressor then the internal parts that require lubrication will begin to rub against each other. This will result in friction and premature wear of not only the components but the overall air compressor.
The oil in an air compressor acts as a lubricant, to stop internal parts from rubbing against each other, causing friction and overheating. The oil helps to maintain the internal mechanisms of an air compressor and ensures that the compressor is able to run at its optimum efficiency.
When your air compressor runs without oil, the internal mechanisms that rely on the lubrication will begin to rub against one another, resulting in friction, high temperatures, and the eventual seizure of the compressor.
