Norgren L68M-NNP-MVN Lubricator - Micro Fog, 10 bar max
Part Number: L68M-NNP-MVN
Quick Summary
Norgren L68M-NNP-MVN lubricator is a micro fog lubricator for general pneumatic systems. Engineers often contend with lubrication inconsistencies on long pipe runs and varying air flows, which can accelerate wear and increase maintenance costs. This design aligns with common industry expectations, including CE safety considerations and compatibility with IP-rated environments, while also supporting SIL reliability thinking for critical automation. With modular Plug-In yoke compatibility and a 5 L metal bowl, it adapts to compact OEM layouts and scalable industrial installations, delivering reliable lubrication where precision matters and downtime is minimized.

FAQs
The L68M-NNP-MVN can be mounted using the optional wall bracket 18-001-979 and compatible with Yoke assemblies Y68A-6GN-N1N or N2N. When a yoke is not used, mountings and ducting should be secured to a stable surface, and ensure the air supply and drain lines are properly connected. This setup maintains modularity and allows easy future yoke integration.
The lubricator delivers up to 175 dm3/sec (371 scfm) with a start point around 6 dm3/sec. The built-in flow sensor maintains a nearly constant oil/air ratio across varying pressures and flows, providing predictable lubrication. This stability is ideal for long piping runs and systems with fluctuating demand.
Yes. The Olympian Plus micro fog design is specifically intended for long and more complex pipework, delivering a fine mist that coats components evenly. It supports general purpose pneumatic applications, OEM lines, and automation cells requiring reliable lubrication over extended distances with minimal maintenance.
This lubricator is designed to align with common industrial standards such as CE safety expectations and general IP-rated environment compatibility. For mission-critical or regulated environments, SIL reliability considerations are typical for automation systems, and users should verify local compliance requirements and any customer-specific certification needs.
Maintenance is supported by a service kit (L68M-KIT) and compatible components like the 5 L bowl and Yoke assemblies. Regular service reduces unexpected downtime, extending service life and lowering total cost of ownership. The modular design enables quick replacements or upgrades, contributing to faster ROI for automation and OEM projects.
