About Air Preparation

Customize your air preparation system with dryers, filters, and other purifying parts.

ARO Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air—joiner clamps (sold separately) connect these regulators into your ARO setup. They connect to other ARO units of the same series, even if the pipe sizes are slightly different, so you can customize your air preparation system. Install them in your air line after your filters.

Relieving regulators exhaust when the downstream pressure exceeds the set pressure. Nonrelieving regulators don’t exhaust any downstream pressure, which is a helpful setup in highly controlled environments. To prevent pressure buildup, manually vent them or use a relief valve.

BSPP threads are also known as G threads.

Joiner clamps (sold separately) create compact, airtight connections between components. These clamps 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.

Knob-locking clips (sold separately) fit under the adjustment knob to prevent unauthorized or accidental changes to the air pressure setting.

Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.

Tamper-Resistant Compressed Air Regulators

With Knob-Locking Clip

Prevent unauthorized or accidental pressure changes to these regulators—they let you lock down the set pressure. Use these regulators to adjust and maintain the pressure of your compressed air. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.

Regulators with a knob-locking clip cannot be adjusted when the clip is installed between the knob and the body of the regulator. To adjust the pressure, remove the knob and clip, then reattach the knob.

Mounting brackets (sold separately) attach the regulator to a wall or equipment.

ARO Modular Compressed Air Filter/Regulators for Particle Removal

Clear Bowl

A filter and regulator stacked together, these filter/regulators clean your compressed air and maintain the pressure. They connect to other ARO units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure. Add a safety lockout valve to prevent accidental start-ups during maintenance and comply with OSHA lockout/tagout regulations.

Bowls with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.

Joiner clamps (sold separately) create compact, airtight connections between components. These clamps come with mounting brackets to attach the filter/regulator to a wall or equipment.

End block sets (sold separately) allow you to swap out components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.

Knob-locking clips (sold separately) fit between the knob and the body of these filter/regulators, preventing unwanted pressure adjustments. To make changes, remove the knob and clip, then reattach the knob.

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

Inline

Stacked

Made up of an ARO filter, regulator, and lubricator, these FRLs provide clean, lubricated air at your required pressure. They connect to other units of the same series with joiner clamps (sold separately)—even if the pipe sizes are slightly different—so you can customize your air preparation system. The regulator is relieving, so it exhausts when the downstream pressure exceeds the set pressure. These FRLs come with mounting brackets, so you can attach them to a wall or equipment. Add a safety lockout valve to prevent accidental start-ups during maintenance and comply with OSHA lockout/tagout regulations.

Inline FRLs are the standard design. Each part can be replaced or repaired on its own, which reduces maintenance costs. Stacked FRLs have a filter and regulator joined top-to-bottom and a lubricator on the side. They require less horizontal space than inline FRLs.

Joiner clamps (sold separately) create compact, airtight connections between components that are easy to swap out. They come with mounting brackets, so you can attach them to a wall or equipment.

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

Shown Installed

Keep air preparation equipment from starting up during maintenance. In their shut-off position, these valves block incoming air and exhaust downstream pressure. You can also lock them closed with a padlock (not included). These valves help you comply with OSHA regulations for lockout/tagout procedures.

Joiner clamps (sold separately) connect these valves to another ARO modular unit with the same series number. They create compact, airtight connections that are easy to swap out. These clamps come with mounting brackets to attach the valve to a wall or equipment.
