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.
The ‘L’ in “FRL”
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.

The modular style ACG series allows you to pick a combination of air preparation equipment that best suit your particular application. The selectable angle of the pressure gauge improves its' visibility, and the anti-revolving mechanism (PAT.PEND.) will not allow the pressure gauge to be revolved even after the handle is operated. Assembly and maintenance are easily performed resulting in reduced downtime and labor savings.
SMC'S new AC-A series of modular type F.R.L. unit is available in five sizes and is interchangeable with the existing modular AC line. The pressure drop across the regulator has been reduced creating a more efficient unit with a maximum set pressure of 100 psi. The element and bowl on the AW and AF series is now one-piece, making element replacement easier. Required maintenance space has been reduced by as much as 46% on the AF series, depending on the body size. Bowls on the size 30 and 40 are now covered with a transparent bowl guard, completely protecting them from the environment, and making the interior contents visible from 360 degrees. The base color of the new AC-A series is urban white, maintaining a clean, modern look.
SMC'S new AC-B series of modular type F.R.L. unit is available in six basic sizes and is interchangeable with the existing modular AC line. The AC-B series has a maximum set pressure of 125 psi and offers embedded gauge and pressure switch options not found in the AC-A. The element and bowl on the AF series is now one-piece, making element replacement easier. Required maintenance space has been reduced by as much as 46% on the AFseries, depending on the body size. Bowls on size 30 and up are now covered with a transparent bowl guard, completely protecting them from the environment, and making the interior contents visible from 360 degrees. The base color of the new AC-B is urban white, maintaining a clean, modern look.
The AC-D series of modular F.R.L. brings a modern appearance to SMC's line of air preparation equipment while maintaining the high performance of our other series. The maximum set pressure of the AC-D is 125 psi allowing use in a broad range of applications. Most of the features of the AC-A and -B have been incorporated into the AC-D - transparent bowl guards for full visibility; embedded gauges and pressure switches; reduced maintenance space and simplified element change on AF-D series filters; urban white color. The AC-D is currently available in three body sizes with more to come in the near future.
The ACG series incorporates the gauge-in-handle regulator or filter-regulator into an air preparation combo. The integrated gauge creates a reduced profile and good visibility of the gauge even when mounted in low or high positions. Size 30 and 40 units now incorporate the transparent bowl guard, protecting them from the environment and providing 360 degrees visibility of the interior. The base color of the new ACG-B is white, maintaining a clean, modern look.

The AW-D is currently available in threee body sizes with more to come in the near future.
A built-in pressure gauge, mountable at any angle, depending on the piping direction ensures good visibility of the pressure gauge, even when the AWG is mounted at an overhead or underfoot location. Equipped with a special mechanism, the pressure gauge will not be revolved even after the handle is operated. Due to the unique design, substantial space reduction is achieved when the AWG is panel mounted. "Note that the AWG-B has been released as a replacement for the AWG. While the AWG is still supported with inventory and no obsolescence date has been announced, we strongly encourage the use of the AWG-B for new applications"
