FRL stands for Filter, Regulator, and Lubricator system.

Air leaving a compressor is hot, dirty, and wet—which can damage and shorten the life of downstream equipment, including valves, cylinders, and air tools. So before compressed air exits the system, it must be cleaned and lubricated. That’s where an FRL comes in! An FRL combines a filter, regulator, and lubricator into one component to keep air compressor systems in optimal working condition.

An FRL has three primary components:

• Airline filter
• Pressure regulator
• Lubricator

Each component has its role, supporting the larger air compressor system.
