What condition should compressor lubricating oil flash points meet for safe operation?

For safe operation of compressors, the flash point of the lubricating oil must be above the compression temperature. The flash point is the lowest temperature at which the oil can vaporize to form an ignitable mixture in air. If the flash point is lower than or equal to the compression temperature, it poses a significant fire hazard because the oil could ignite under normal operating conditions, leading to serious safety risks.

By ensuring that the lubricating oil's flash point is above the compression temperature, operators can effectively reduce the risk of fire or ignition. This is crucial in maintaining a safe working environment and ensuring the reliability of the compressor system. Meeting this condition is a key aspect of operating compressors safely and effectively.
