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.

Space-Saving Compressed Air Filter/Regulators for Oil and Particle Removal

A two-stage filter and regulator joined top-to-bottom, these filter/regulators provide clean, compressed air at the pressure you need. Two-stage filtration is like getting two filters in one—the first stage removes large particles, while the second removes fine particles. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.
Bowls with an automatic drain periodically release condensate into the air, so there’s no 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.
Mounting brackets (sold separately) allow you to attach the filter/regulator to a wall or equipment.
