Also known as coalescing filters, these filters remove compressor oil to extend the service life of air-powered tools and equipment. Joiner clamps (sold separately) connect these air filters into your Norgren setup. These filters connect to other Norgren units of the same series—even if the pipe sizes are slightly different—so you can customize your air preparation system. All filters have a clear bowl, so you can monitor the liquid level inside. You’ll know it’s time to replace the filter element when the service indicator at the top of the unit turns red. To prevent clogs, install a particle filter before the oil filter.

Series no. 82 and 84 only require minimal clearance to remove the bowl for maintenance—the filter element moves with the bowl rather than staying attached to the body—making it easy to replace the filter element.

Filters with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.

Mounting brackets (sold separately) 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.

End block sets (sold separately) let you swap out filter/regulator/lubricator components without unthreading your air line connections. These blocks stay connected to your pipe while you replace the components installed between them.

Replace a damaged bowl on your Norgren modular compressed air filter, or swap in a different material or drain type. These bowls come with an O-ring to ensure a tight seal. They have either a clear bowl or a sight glass so you can monitor the liquid level inside. Check the manufacturer series on your filter to ensure compatibility.

Bowls with an automatic drain are best for air lines that have high water content, run continuously, or are hard to reach. Bowls with a manual drain are easy to empty, so they’re often used in systems with a steady, predictable buildup of condensate.

Aluminum bowls are more durable than plastic, so they hold up better to bumps and drops.
