Parker Modular Compressed Air Filter/Regulator/Lubricators (FRLs)
A Parker filter, regulator, and lubricator are combined to provide clean, lubricated compressed air at your required pressure. They come with a safety lockout valve for one convenient unit that's ready to use. The valve can be locked in the shut-off position to prevent accidental start-up when servicing equipment. Regulator is relieving style, so it exhausts when the downstream pressure exceeds the set pressure. Filter and lubricator have a clear bowl 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.
Mounting brackets allow you to attach the filter/regulator/lubricator to a wall or equipment.

Joiner Clamps for Parker Modular Compressed
Air Filter/Regulator/Lubricators (FRLs)


Connect Parker modular filter/regulator/lubricator components with the same series number. Even with slight differences in inlet sizes or thread types, these joiner clamps connect without air leaks. Check the manufacturer series on your Parker components to ensure compatibility.
Joiner clamps with a mounting bracket secure components to each other and to a wall or equipment.
End Block Sets for Parker Modular Compressed
Air Filter/Regulator/Lubricators (FRLs)

Swap out Parker modular filter/regulator/lubricator components without unthreading your air line connections. These blocks remain connected to your pipes while you replace components between them. Check the manufacturer series on your Parker components to ensure compatibility.
BSPP threads are also known as G threads.
Manifold Blocks for Parker Modular Compressed
Air Filter/Regulator/Lubricators (FRLs)

Distribute compressed air to multiple locations from a single source. These manifolds connect with Parker modular components that have the same manufacturer series.
Use joiner clamps to connect the manifold block to another Parker modular unit with the same series number.
Parker Compressed Air Filter Elements for Particle Removal

Replace the filter element in your Parker modular compressed air filter to trap solid particles and water droplets. To extend the life of your filter, choose the coarsest (highest micron) element that meets your air quality needs. Check the manufacturer series on your filter to ensure compatibility.

Parker Compressed Air Filter Elements for Oil Removal

Also known as coalescing filters, these filter elements fit into Parker modular compressed air filters to remove oil and fine particles. Check the manufacturer series on your filter to ensure compatibility.
Elements that remove oil filter out liquid oil. Those that remove particles down to 1 micron are less likely to clog than those that filter to .01 microns. Use them for general purpose compressed air, or as a prefilter to protect higher purity filters from clogs. Those that remove particles down to .01 microns provide the high filtration necessary to protect sensitive equipment. They’re often used for paint spraying or electronics manufacturing.
Elements that remove oil vapor trap the smallest contaminants, including odors, with activated carbon. Use them for applications where air purity is critical, such as food processing or pharmaceutical production. They're also known as Adsorber filters.
Parker Compressed Air Filter Bowls

Replace a damaged bowl or change the bowl material or drain type on your Parker modular compressed air filter. These bowls come with an O-ring to ensure a tight seal. Check the manufacturer series on your filter to ensure compatibility.
Bowls with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.
Clear bowls and opaque bowls with sight glass allow you to see inside to monitor their contents.

Parker 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. Joiner clamps (sold separately) connect these air filters into your Parker setup. These filters connect to other Parker units of the same series—even if the pipe sizes are slightly different—so you can customize your air preparation system.
Filters with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.
Mounting brackets (sold separately) can be added to series P3Y filters to secure the filter to a wall or your equipment.
Joiner clamps (sold separately) create compact, airtight connections between components. These clamps come with mounting brackets, except for series P3Y.

Parker 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. They connect to other Parker 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. To prevent clogs, install a particle filter before the oil filter.
Filters with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.
Filters with a service indicator make it easy to know when it’s time for a filter element replacement. When the indicator at the top of the unit turns red, the filter element is ready to be replaced.
Use joiner clamps to connect the filter to another Parker modular unit with the same series number. These clamps come with mounting brackets, except for series P3Y.
When using series 11 and series 12 filters with their compatible components, your maximum flow rate will be the lower of the two components.

Parker Modular Compressed Air Regulators

Adjust and maintain the pressure of your compressed air. These regulators connect to other Parker units of the same series with joiner clamps (sold separately), so you can customize your air preparation system. All are relieving style, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after filters.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
