What can be a consequence of operating a compressor with low oil levels?

Operating a compressor with low oil levels can lead to significant overheating because oil serves as both a lubricant and a coolant for the internal components of the compressor. When oil levels drop, there is inadequate lubrication, which increases friction and leads to higher operating temperatures. This overheating can not only damage the compressor internally but may also create fire hazards, as elevated temperatures can ignite flammable substances present in the environment or the compressor itself.

In contrast, increased lifespan, higher efficiency, and decreased noise levels would generally correlate with well-maintained equipment that has adequate lubrication. Insufficient oil does not contribute positively to any of these factors; rather, it tends to have the opposite effect over time. Thus, managing oil levels is crucial for safe and effective compressor operation.
