About Air Preparation

Adjust and maintain the pressure of your compressed air. These regulators are relieving style, so they exhaust when the downstream pressure exceeds the set pressure.

These regulators connect to other Aventics units of the same series—even if the pipe sizes are slightly different—so you can customize your air preparation system. Their clamps (sold separately) create compact, airtight connections that are easy to swap out. Install them in your air line after filters.

Add mounting brackets to attach the regulator to a wall or your equipment.

Use joiner clamps to connect the regulator to another Aventics modular component with the same series number. These clamps come with mounting brackets.

Tamper-Resistant Compressed Air Regulators

With Key Lock

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 key lock only let those with the key adjust the pressure. The lock is universal, so you can use the same key for multiple regulators.

Aventics Modular Compressed Air Filter/Regulators for Particle Removal

Connect these filter/regulators to other Aventics units of the same series with joiner clamps (sold separately) to customize your air preparation system. A filter and regulator joined top-to-bottom, they provide clean, compressed air at the pressure you need. 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.

Bowls with a semi-automatic drain release their condensate whenever your system is depressurized. You can also empty the drain manually.

Joiner clamps (sold separately) create compact, airtight connections between components, even if the pipe sizes are slightly different. They come with mounting brackets to attach the filter/regulator to a wall or equipment.

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

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

Inline

Stacked

A combination of an Aventics 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.

Their bowls have a semi-automatic drain that releases condensate whenever the system is depressurized. You can also empty the drain manually. Mounting brackets let you attach these FRLs 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.

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

Shown Installed

Keep your air preparation equipment from turning on 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 Aventics 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.
