Norgren L68C-NNP-EUQ Oil Fog Lubricator - Olympian Plus
Part Number: L68C-NNP-EUQ
Quick Summary
Norgren L68C-NNP-EUQ Oil Fog Lubricator provides controlled oil-air lubrication for heavy-duty pneumatic cylinders and tools. A common challenge is keeping a constant oil stream over short runs, which this unit addresses with a built-in flow sensor. Note: The product data does not specify CE, SIL, or IP ratings; refer to the datasheet for certification status. The Olympian Plus yoke Plug-In system delivers modularity, while an aluminium body and closed-bowl design support durable operation across -20 to 80 °C environments. With compatible accessories and a service kit, you can tailor lubrication performance to your application, boosting efficiency and reducing maintenance costs.

Feature: Olympian Plus yoke Plug-In system enables modular installation and fast upgrades. Business Impact: Minimizes downtime during line changes and simplifies stocking of spare parts. Application: Retrofit on existing installations or scalable deployments across multiple lines. Long-tail keywords: Olympian Plus, plug-in yoke system, modular lubrication. The flow sensor maintains a nearly constant oil-air ratio across flow ranges, delivering consistent lubrication. Business Impact: Improves tool life and process stability, reducing scrap and rework. Application: Heavy lubrication requirements for large bore cylinders, air motors and air tools. The system supports a wide range of flow—from a start point of 6 dm3/sec to up to 175 dm3/sec (371 scfm)—and a maximum inlet pressure of 17 bar. Business Impact: Flexible to varying demand without oversized manifolds. Application: High-throughput automation lines needing rapid response. Long-tail keywords: flow sensor, oil-air ratio, high-flow lubrication. Aluminum body and bowl deliver robust durability in tough environments, while a closed bowl design minimizes oil mist and simplifies maintenance. Business Impact: Longer service intervals and cleaner workspaces. Application: Industrial facilities with strict housekeeping standards. The product’s materials compatibility (aluminium body and bowl, nitrile elastomers) supports reliable operation across a broad temperature range (-20 to 80 °C). Long-tail keywords: aluminium lubrication system, nitrile elastomers, wide operating temp range. Optional components such as Y68A yoke assemblies (N1N/N2N), wall bracket 18-001-979, and the service kit L68C-KIT enable tailored configurations. Business Impact: Reduced downtime and optimized service planning. Application: Customizable solutions for OEMs and maintenance teams.

FAQs
The unit uses the Olympian Plus Plug-In yoke system; install the bowl and body with the Y68A-6GN-N1N or N2N yoke assemblies and mount using the wall bracket 18-001-979. Ensure correct inlet supply and ensure the port size is compatible with ‘Without Yoke’ configurations and any required adapters. This setup enables rapid upgrades and straightforward field maintenance.
Operating temperature ranges from -20 to 80 °C (-4 to 176 °F), suitable for most factory ambient conditions. The maximum inlet pressure is 17 bar, which accommodates a wide range of compressed air systems while maintaining reliable oil-lubricant delivery.
Flow is rated at 175 dm3/sec (371 scfm) with a start point of 6 dm3/sec, enabling precise scale-up for multiple tools or larger bore cylinders. This flexibility supports both light and heavier lubrication needs within a single unit.
Yes, the bowl is closed, which helps minimize oil mist and reduces housekeeping requirements. This design simplifies containment and makes integration into enclosed or shared-service areas more practical.
Available accessories include Yoke assemblies (Y68A-6GN-N1N and N2N), a wall bracket (18-001-979), and the service kit L68C-KIT. These options support custom configurations, faster maintenance, and extended system life for OEMs and maintenance teams.
