Combination Units

Filter, regulator, & lubricator (FRL) units are combination air preparation components. These are essential for pneumatic systems in a diverse range of commercial and industrial applications.

They play a crucial role in maintaining the quality of compressed air. Furthermore, they protect downstream equipment, and improve the efficiency and lifespan of your pneumatic system.

At Orange Coast Pneumatics, we offer an expansive collection of FRL units from the SMC Corporation of America. Find the best solution for your operations here; then, continue reading to learn more about the benefits of these essential pneumatic components.

What Does “FRL” Mean in Pneumatics?

In pneumatics, FRL stands for "Filter, Regulator, Lubricator." This three-in-one component combines the functions of filtering, regulating, and lubricating compressed air before it enters a pneumatic system.

What is the Function of a Pneumatic FRL?

The filter element of an FRL unit is designed to remove contaminants such as dirt, oil, and water from the compressed air. These contaminants may cause damage to downstream equipment and reduce the overall efficiency of the system. 

The filter element is typically made of materials like sintered bronze, pleated paper, or synthetic media, depending on the level of filtration required. The regulator function of the FRL unit is responsible for controlling the pressure of the compressed air that enters the system. 

This is crucial for ensuring that downstream equipment operates within the specified pressure range and isn’t damaged due to overpressure. The regulator typically consists of a diaphragm or piston that responds to changes in pressure and adjusts the output pressure accordingly.

Finally, the lubricator function of the FRL unit is responsible for injecting a small amount of oil mist into the compressed air. This lubricates downstream components such as valves, cylinders, and actuators. 

Lubrication is vital for ensuring smooth operation of the system. Additionally, lubrication reduces the wear and tear on moving parts over extended periods of time.
