Change Oil in an Air Compressor

As you might know, oil plays a crucial role in keeping your air compressor performing at its peak. It serves as a coolant as well as a lubricant to keep the interior components fresh and moving smoothly. In addition, it also seals up any small openings between the parts inside the compressor effectively sealing it.

Without fresh oil, the compressor can face issues such as overheating or inefficient compression of air. The oil keeps the interior components clean and prevents clogging. Besides, without oil in your compressor, the unit will deteriorate over time until one day it completely breaks down.

To keep your compressor working at its finest, you need to schedule oil changes depending on the type of unit you are using. If you have one of those rotary screw compressors, you should be looking at an oil change after around a thousand hours of usage.

For a reciprocating air compressor, you need to change the oil every three months.
