Norgren Modular Compressed Air Lubricators

Add lubrication to your air supply to extend the service life of air-powered tools and equipment. These lubricators connect to other Norgren 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. They’re long-range lubricators, so they can power multiple tools or machines across extended systems. They produce an ultra-fine mist with oil particles smaller than 2 microns that can travel both uphill and far downstream.
Install these lubricators in your air line after filters and regulators. You can see inside the bowl to check the oil level for refilling. Adjust the amount of lubricant in the air based on your equipment's performance. If your machine is running loudly or showing signs of wear, increase the amount; if you notice oil building up, decrease it.
Mounting brackets (sold separately) allow you to attach the lubricator to a wall or equipment.
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 components without unthreading your air line connections. The blocks remain connected to your pipe while you replace components between them.
