Product Description
The air line Filters, Regulators, Lubricators, Filter/Regulators and Combination Units are intended for use in industrial compressed air systems
only. No other use is recommended.
Filters
ARO compressed air filters are designed to remove airborne solid and liquid contaminant’s which may plug small orifices and hinder
performance, or cause excessive wear and premature equipment failure. Several filter elements are offered, including models with coalescing
elements for removal of oil aerosols and particles down to 0.3 micron.
Regulators
ARO air line regulators provide controlled, consistent air pressure as required for specific pneumatic equipment connected to the air system.
Standard relieving-type regulators are offered in a variety of adjustable pressure ranges, with convenient spring options for easy conversion
should requirements change. Non-relieving models are also offered for applications where the venting of downstream overpressure is undesirable.
Lubricators
ARO fog-type lubricators help ensure that pneumatic devices receive the required lubrication to maintain operating 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 CFM. Precise oil feed adjustment allows the proper oil delivery rate. Lubricators should be installed close to
the downstream application to ensure effective distribution of oil to the pneumatic components.
Filter/Regulators
ARO compressed air filter/regulators are designed to remove airborne solid and liquid contaminant’s which may plug small orifices and hinder
performance, or cause excessive wear and premature equipment failure. Several filter elements are offered, including models with coalescing
elements for removal of oil aerosols and particles down to 0.3 micron. In addition to filtration the regulators portion provides controlled,
consistent air pressure as required for specific pneumatic equipment connected to the air system. Standard relieving-type regulators are offered
in a variety of adjustable pressure ranges, with convenient spring options for easy conversion should requirements change. Non-relieving
models are also offered for applications where the venting of downstream overpressure is undesirable.
Combination Units
ARO combination units are an assembled version of a filter, regulator and lubricator or a filter/regulator and lubricator. See Product Descriptions
above for individual descriptions of components.

Operation – Lubricators
• Use a good grade of non-detergent oil (IR part # 29665) for use in the air operated equipment. Refer to the air operated equipment
operator’s manual.
Note: This lubricator uses a ball check valve located in the lubricator body to restrict the operating pressure to the bowl and allow removal of
the fill plug. This will permit filling or lubricator bowl removal while in the normal operating mode.
• Observe the markings (-,+) on the lubricator body which show direction. Turn the adjustment screw counterclockwise to increase and
clockwise to decrease.
Lubricator Adjustment:
Note: This is a siphon type lubricator design, adjustments need to be made with a constant rate of flow thru the lubricator in an operating
mode.
• Use a small screwdriver to adjust the drip rate. The adjustment screw is located in the sight feed cap on the top of the lubricator.
• Determine the average rate of flow (SCFM) thru the lubricator, then turn the adjustment screw to obtain one drop per minute for each 10
SCFM. Example: If the average flow is 20 SCFM, set the drip rate at 2 drops per minute.
Note: The fill plug must be removed to allow removal of the lubricator bowl or filling of the unit.
• Remove the fill plug carefully.
