Filters, Regulators & Lubricators (FRLs)

Another popular combination of filters, regulators, and lubricators is the F/R+L (two-piece combo) arrangement. More configurations may be used depending on your application needs. ARO-Flo combination FRLs are easy to assemble using modular spacer kits.

Filters, regulators, lubricators, and piggybacks can be combined together to form combinations. They are typically strung together in the F+R+L arrangement (three-piece combo) and F/R+L (two-piece combo) arrangement, although other configurations are also used depending on application needs. ARO-Flo combination FRLs are easily assembled using modular spacer kits.

ARO-Flo compressed air filters are designed to remove airborne solid and liquid contaminants. Filters can be ordered with different elements, including coalescing models which are capable of removing oil aerosols and particles down to 0.3 micron. Standard filters are sold with 5-micron elements; 40-micron elements can be purchased and installed separately.

Air line regulators provide controlled consistent air pressure as required for specific pneumatic equipment connected to the air system. All ARO-Flo regulators are offered with a standard adjustment range of 0-140 psig (0-9.6 bar). Alternative spring ranges are offered for easy conversion to suit different requirements. Non-relieving regulators are offered for applications where the venting of downstream overpressure is undesirable.

ARO-Flo mist-type lubricators help ensure that pneumatic devices receive the required lubrication to maintain peak performance, reduce wear, and prolong service life. They are designed to provide the correct amount of oil required for most general applications in a pneumatic system, delivering a constant ratio of oil to airflow. Precise oil feed adjustment sets the proper oil drip rate. Lubricators should be installed close to the downstream application to ensure the effective distribution of oil.

ARO offers a variety of accessories and replacement parts to enable greater customization and flexibility for your application. Lockout valves, check valves, mounting brackets, manifolds, soft start valves, gauges, and pipe adapters are available in several sizes and configurations to fit your needs.
