An FRL unit is comprised of a filter (F), regulator (R), and a lubricator (L). They are often used as one unit to ensure clean air in a pneumatic system but can also be used individually. ... Filters remove water, dirt and other harmful debris from an air system. This is often the first step in improving the air quality.

What is the function of FRL unit in pneumatic control system?

Pneumatic Lubricators

Like pressure regulators, the lubricator function of an FRL unit ensures that the air is dosed with a small amount of lubrication oil to help pneumatic components work effectively. Lubricators ensure that the correct amount of oil is being used to reduce the friction between moving components.
