Norgren L68C-NNP-ERQ Oil Fog Lubricator - Olympian Plus
Part Number: L68C-NNP-ERQ
Quick Summary
Norgren L68C-NNP-ERQ is an oil fog lubricator that precisely lubricates compressed air for large-bore cylinders and air tools. Operators often struggle with uneven lubrication and bowl maintenance in demanding applications, leading to wear and downtime. Certifications vary by market; verify CE, IP ratings, and SIL status in the datasheet. The Olympian Plus design with a plug-in yoke system offers modularity, while an aluminium body and closed-bowl construction support durable, easy-to-service installation. This combination reduces maintenance costs and improves tool life, with compatible bowl options and a defined start flow for predictable lubrication in industrial automation lines.

The Olympian Plus plug-in yoke system provides modularity that lets you reconfigure lubrication points quickly as line layouts change, reducing downtime during line upgrades. This modularity translates to lower spare-part variety and faster field adjustments for evolving production needs, making it ideal for multi-station assemblies and retrofit projects. Oil fog lubrication is particularly effective for heavier lubrication over short distances, delivering richer oil coverage to large bore cylinders, air motors, and air tools while maintaining a clean, compact installation. The result is improved tool life and reduced operator intervention in high-demand environments, supporting lean manufacturing and consistent performance. A built-in flow sensor maintains a nearly constant oil/air ratio across a broad flow range, cutting waste and stabilizing process variables in variable-velocity lines common in automation cells. Optional bowl sizes provide maintenance flexibility, enabling operators to balance refill frequency with line uptime while controlling condensate and oil hold-up. Aluminium body and aluminium bowl deliver robust corrosion resistance and long service life in challenging industrial settings, with nitrile elastomer seals contributing to reliable operation across a wide temperature span. Drain type is a closed bowl, minimizing oil mist and splash in clean-room-adjacent areas or splash-sensitive environments. When combined with compatible Yoke assemblies (Y68A-6GN-N1N/N2N) and mounting accessories like the Wall Bracket 18-001-979, installation is straightforward on existing frames or new lines. A dedicated service kit, L68C-KIT, simplifies preventive maintenance and extends lifecycle in manufacturing plants where uptime is critical.

FAQs
This model features a port size without yoke by default but supports optional Yoke assemblies (Y68A-6GN-N1N, N2N) for modular mounting. It can be mounted using the Wall Bracket 18-001-979 and other compatible hardware, enabling easy integration into existing frames or new lines without major rework.
Expect a maximum inlet pressure of 17 bar, flow up to 175 dm3/sec (371 scfm), and a start point at 6 dm3/sec. Operating temperature ranges from -20 to 80 °C, with a closed-bowl drain design to minimize spillage. This makes it suitable for mid- to high-demand pneumatic systems on industrial lines.
Yes. The oil fog technology and adjustable flow ensure adequate lubrication for larger bore cylinders and high-load air tools over short to moderate distances. The robust aluminium construction and closed-bowl design help maintain lubricant delivery under fluctuating line pressures common in heavy-duty automation.
To keep performance consistent, use the L68C-KIT service kit for routine maintenance. The kit supports routine replacements of seals and wear items, while the modular yoke system simplifies access during scheduled maintenance, reducing downtime and ensuring long service life in busy production environments.
The built-in flow sensor preserves a nearly constant oil/air ratio across varying flow rates, reducing oil waste and preventing over- or under-lubrication. This stability translates to more predictable tool life, lower maintenance costs, and improved consistency in processes with variable demand, such as batch production or rapid changeovers.
