ARO Modular Compressed Air Lubricators

Add lubrication to your air supply to extend the service life of air-powered tools and equipment. Lubricators have a clear bowl or sight glass so you can see inside to view the oil level. Install in your air line after filters and regulators.
Joiner clamps (sold separately) connect the lubricator to another ARO modular component with the same series number. They come with mounting brackets to attach the lubricator to a wall or equipment.
End block sets (sold separately) allow you to swap out filter/regulator/lubricator components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.

ARO Compressed Air Lubricator Bowls

Replace a damaged bowl, or change the bowl material on your ARO modular compressed air lubricator. Bowls come with an O-ring to ensure a tight seal. Check the manufacturer series on your lubricator to ensure compatibility.

ARO Modular Compressed Air Filter/Regulator/Lubricators (FRLs)


An ARO filter, regulator, and lubricator are combined to provide clean, lubricated compressed air at your required pressure. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Filter and lubricator have a clear bowl or sight glass so you can monitor the contents inside.
Stacked filter/regulator/lubricators require less horizontal space than inline FRLs. The filter and regulator are joined top-to-bottom with the lubricator on the side.
Mounting brackets allow you to attach the filter/regulator/lubricator to a wall or equipment.
Joiner clamps (sold separately) connect the filter/regulator/lubricator to another ARO modular component with the same series number. They come with mounting brackets.
End block sets (sold separately) allow you to swap out filter/regulator/lubricator components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.
