What is a sign that the lubricator is misadjusted?

The presence of oil misting from exhaust ports is a clear indicator that the lubricator is misadjusted. This phenomenon occurs when the lubricator is set to deliver too much oil into the air stream, resulting in an excessive amount of lubricant being carried into the system. This oil can then escape through exhaust ports, creating a visible mist in the air.

Proper lubrication is essential in pneumatic systems to ensure the optimal performance and longevity of components, but the correct amount must be regulated. If the misting is observed, it signifies that adjustments need to be made to the lubricator to prevent interference with the operation of the components downstream, which could lead to inefficient performance or operational issues. The visibility of this oil mist serves as a warning to operators that they need to address the settings on the lubricator to ensure proper function.
