Norgren L68C-NNE-EUN Olympian Plus Oil fog lubricator - High Flow
Part Number: L68C-NNE-EUN
Quick Summary
L68C-NNE-EUN oil fog lubricator delivers precise lubrication for compressed air systems in automation environments. Engineers often struggle with maintaining a constant oil-to-air ratio as line loads fluctuate or tool demands shift. This design supports CE conformity and is compatible with IP-rated enclosures and SIL-focused safety practices in modern plant environments. The modular Plug-In yoke system alongside a 1 L aluminium bowl with a closed-drum drain reduces maintenance downtime, while the high-flow capability supports lubrication for large-bore cylinders, air motors, and heavy pneumatic tools. Overall, it delivers reliable, scalable lubrication for demanding manufacturing lines and automated equipment setups.

Feature: Unique Olympian yoke Plug-In system offers perfect modularity. Business Impact: Speeds up installation and enables scalable configurations across multiple stations without tools or extensive rework. Application: Ideal for multi-circuit lines in automation plants where quick swaps and future expansions are common. Feature: Oil fog lubrication provides heavier lubrication over short distances. Business Impact: Improves tool life and reduces wear in high-load pneumatic systems, lowering maintenance costs. Application: Large bore cylinders, air motors, and air tools in manufacturing cells benefit from consistent lubrication. Feature: Flow sensor maintains a near-constant oil/air ratio across a range of flows. Business Impact: Minimizes lubricant waste and ensures predictable performance, aiding process consistency and quality control. Application: Pipelines that experience load variation maintain stable output. Feature: 1 L aluminium bowl with closed drain. Business Impact: Durable, spill-resistant reservoir that minimizes downtime and simplifies containment in harsh industrial environments. Application: Heavy-use lines where quick bowl maintenance is essential. Feature: Materials - Body and Bowl are aluminium; Elastomers are nitrile rubber. Business Impact: Corrosion resistance and chemical compatibility extend service life in oil-laden environments. Application: Widely used in OEM lines and retrofit projects in automation. Feature: Compatibility with accessories (Yoke assemblies, Wall Bracket, Service Kit). Business Impact: Streamlines installation and maintenance with ready-made add-ons, reducing integration time. Application: Retrofit projects and new installations across factory floors.

FAQs
Install the L68C-NNE-EUN using the Plug-In yoke system for rapid, modular mounting. If a different mounting method is required, you can use Yoke assemblies Y68A-6GN-N1N or Y68A-6GN-N2N and mount to a compatible wall bracket such as 18-001-979. Ensure the inlet pressure does not exceed 17 bar and verify the drain is a closed bowl type for spill containment.
This unit excels in heavy lubrication over short distances, making it ideal for large bore cylinders, air motors, and pneumatic tools. With a 1 L aluminium bowl and oil fog lubrication, it delivers a stable oil-to-air ratio across a high-flow range, supporting reliable performance in automation cells and tooling stations.
The L68C-NNE-EUN is designed to support CE conformity and is compatible with typical industrial protection schemes such as IP-rated enclosures and SIL-focused safety strategies. Actual certification status and applicability depend on complete system integration and the enclosure used; consult the installation guide for exact compliance guidance.
Periodic inspection of the closed-bowl reservoir and elastomer seals is recommended. Use the service kit L68C-KIT for routine maintenance, replace the nitrile rubber elastomers when worn, and check the flow range (start point to full flow) to ensure the oil-air ratio remains stable. Consider the L68C-compatible Wall Bracket 18-001-979 for easier servicing access.
Expect improved consistency in lubrication, reduced lubricant waste due to an integrated flow sensor, and faster maintenance cycles thanks to the Plug-In modular yoke system. These factors translate to lower tool wear, higher uptime, and predictable process performance across automated lines and high-demand pneumatic systems.
