    About Air Preparation
    industrial info icon

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

    Festo Modular Compressed Air Filter/Regulators for Particle Removal

    A filter and regulator joined top-to-bottom, these filter/regulators provide clean, compressed air at the pressure you need. They connect to other Festo units of these 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.
    Slip a padlock through a hole in the knob to prevent unwanted pressure changes. Add a safety lockout valve to prevent accidental start-ups during maintenance and comply with OSHA lockout/tagout regulations.

    Corrosion-Resistant Compressed Air Filter/Regulators for Particle Removal

    Bowl

    Built to resist corrosion, these filter/regulators withstand harsh environments that would cause standard filter/regulators to break down and fail. The filter and regulator are joined top-to-bottom, so they fit in the same space as a filter alone. They provide clean compressed air at your required pressure. The regulator is relieving, so it will exhaust when the downstream pressure exceeds the set pressure.
    Stainless Steel Bowl—Stainless steel filter/regulators stand up to harsh chemicals and chlorides, so they're often used in facilities that manufacture semiconductors, chemicals, and paper. Their housing and bowl meet NACE (National Association of Corrosion Engineers) standards for performance in corrosive environments.

    Compressed Air Filter/Regulators for Particle Removal with Push-to-Connect Fittings

    Image of Product. Front orientation. Compressed Air Filter/Regulators. Compressed Air Filter/Regulators for Particle Removal with Push-to-Connect Fittings.
    Designed for quick installation on your air line, these filter/regulators don’t require pipe nipples or joiner clamps. Their push-to-connect fittings create airtight seals on tubing. A filter and regulator joined top-to-bottom, these filter/regulators 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.
    Mounting Brackets—Mounting brackets (sold separately) allow you to attach the filter/regulator to a wall or equipment.
