What role does a lubricator play in an FRL unit?

In an FRL (Filter, Regulator, Lubricator) unit, the primary role of a lubricator is to add lubricant to the compressed air system. This is crucial because compressed air can cause wear and tear on pneumatic components, such as valves and actuators, over time due to friction and lack of lubrication. The lubricator introduces an appropriate amount of oil, which helps to reduce friction, minimize wear, and extend the life of pneumatic devices. Proper lubrication is essential for maintaining efficient operation and preventing damage caused by dry air.

While filtering impurities and regulating pressure are important functions performed by other components in the FRL unit, they do not pertain to the specific role of the lubricator. Thus, the lubricator’s function of introducing lubricant is fundamental to ensuring the longevity and efficiency of the pneumatic system.
