What can result from operating an air compressor without sufficient lubrication?

Operating an air compressor without sufficient lubrication can lead to overheating and potentially catastrophic failure. Lubrication is essential for reducing friction between the moving parts of the compressor. When these components are not properly lubricated, they generate excessive heat due to increased friction. This overheating can cause significant wear and tear on the compressor, leading to component failure. In severe cases, it can result in a complete breakdown of the machinery, which poses safety risks and necessitates expensive repairs or replacements.

In contrast, options related to improved efficiency, air quality, or reduced noise do not align with the consequences of inadequate lubrication. Insufficient lubrication does not contribute to better fuel efficiency or cleaner air; instead, it adversely affects the overall performance and reliability of the compressor. Additionally, inadequate lubrication typically leads to higher operational noise due to rough internal contact and failure.
