ARO Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air. Install these regulators in your air line after filters.
Relieving regulators exhaust when the downstream pressure exceeds the set pressure.
Nonrelieving regulators do not exhaust excess downstream pressure.
BSPP threads are also known as G threads.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
Joiner clamps (sold separately) connect the regulator 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.

ARO Modular Compressed Air Filter/Regulators for Particle Removal

A filter and regulator joined top-to-bottom, these filter/regulators fit in the same space as a filter alone. They provide clean compressed air at your required pressure. Filter has a clear bowl or sight glass so you can see inside to monitor contents. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure.
Joiner clamps (sold separately) connect the filter/regulator to another ARO modular component with the same series number. They come with mounting brackets to attach the filter/regulator 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 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.

Safety Lockout Valves for ARO Modular
Compressed Air Filter/Regulator/Lubricators (FRLs)

Prevent accidental start-up when servicing equipment. These lockout valves exhaust downstream pressure and can be locked in the shut-off position using a padlock (not included). Valves help your process comply with OSHA regulations for lockout/tagout procedures.
Joiner clamps (sold separately) connect the safety lockout valve to another ARO modular component with the same series number. They come with mounting brackets to attach the valve to a wall or equipment.
