Festo Modular Compressed Air Filters for Particle Removal

Extend the service life of air-powered tools and equipment by removing particles and water droplets from compressed air. Filters have a clear bowl or a sight glass so you can see inside to monitor contents.
Joiner clamps (sold separately) connect the filter to another Festo modular component with the same series number. They come with mounting brackets to attach the filter 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.

Compressed Air Filters for Particle Removal with Push-to-Connect Fittings

Quickly install these filters on your air line—no pipe nipples or joiner clamps required. Their push-to-connect fittings create tight seals around tubing. These filters extend the service life of air-powered tools and equipment by removing particles and water droplets from compressed air. Small and made of lightweight plastic, they can be easily mounted onto machines or robotic arms to protect end-of-arm tools. A clear bowl lets you see inside to monitor their contents.
Mounting brackets (sold separately) allow you to attach filters to a wall or equipment.
Festo Compressed Air Filter Elements for Particle Removal

Replace the filter element in your Festo modular compressed air filter to trap solid particles and water droplets. To extend filter life, choose the coarsest (highest micron) option that still meets your air quality needs. Check the manufacturer series on your filter to ensure compatibility.
Festo Compressed Air Filter Elements for Oil Removal

Also known as coalescing filters, these filter elements fit in Festo modular compressed air filters to remove oil and particles as small as 0.01 microns. Check the manufacturer series on your filter to ensure compatibility.
Festo Modular Compressed Air Filters for Oil Removal

Also known as coalescing filters, these filters remove compressor oil to extend the service life of air-powered tools and equipment. Filters have a clear bowl or a sight glass so you can see inside to monitor contents. To prevent clogs, install a particle filter before the oil filter.
Joiner clamps (sold separately) connect the filter to another Festo modular component with the same series number. They come with mounting brackets to attach the filter 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.

Festo Compressed Air Filter Bowls

Replace a damaged bowl, or change the drain type on your Festo modular compressed air filter. Bowls come with an O-ring to ensure a tight seal. Check the manufacturer series on your filter to ensure compatibility.
Festo Compressed Air Filter Seals

Replace failing or lost O-rings in Festo modular compressed air filters. Check the manufacturer series on your filter to ensure compatibility.
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.
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.

Corrosion-Resistant Compressed Air Filter/Regulators for Particle Removal
Manual
Drain
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.
316 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.

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


A Festo 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.
Joiner clamps (sold separately) connect the filter/regulator/lubricator to another Festo modular component with the same series number. They come with mounting brackets to attach the filter/regulator/lubricator 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.
