Norgren L68M-NNP-ERN Lubricator - Micro Fog
Part Number: L68M-NNP-ERN
Quick Summary
Norgren L68M-NNP-ERN micro fog lubricator enables precise lubrication for general pneumatic systems. When variable oil flow or long pipe runs cause inconsistent lubrication and maintenance overhead, this solution delivers reliable plug-in modularity with minimal downtime. While certifications vary by region, pneumatic components typically align with CE marking, IP ratings, and safety standards to support reliable operation. This design leverages an aluminium body and closed bowl for durability in harsh environments, with a flow sensor maintaining a nearly constant oil/air ratio and optional bowl sizes for scalability. By combining modularity, low lubricant consumption, and straightforward maintenance, it supports uptime, reduced operating costs, and predictable performance across multiple lines.

Plug-in yoke modularity enables fast configuration changes and reduces downtime, delivering quicker line changes and less tool time during maintenance. This translates to lower total cost of ownership and higher production uptime in automated systems. The micro fog lubrication profile provides a fine mist that minimizes excess oil carryover while delivering reliable lubrication across general pneumatic lines, improving actuator life and reducing service intervals. A flow sensor maintains a nearly constant oil-to-air ratio across a range of flows, which reduces waste and ensures consistent performance even as system demand shifts. The aluminium body and aluminium bowl deliver robust durability in industrial settings, while nitrile rubber elastomer seals resist chemical attack and wear, extending service life in tough environments. Compatibility with optional bowl sizes and Yoke assemblies (Y68A-6GN-N1N/N2N) simplifies integration into existing L68M-based installations and supports scalable retrofits. Together, these features drive predictable performance, improved energy efficiency, and lower maintenance costs over the equipment lifecycle.

FAQs
The L68M-NNP-ERN is configured as a port-size without a fixed yoke, enabling straightforward integration with Yoke assemblies such as Y68A-6GN-N1N and Y68A-6GN-N2N. For complete compatibility, consider the L68M-KIT service package and the available bowls. This setup supports quick field adjustments, reduces downtime during replacement, and helps you tailor lubrication capacity to your line requirements without replacing the entire unit.
Key figures include a maximum inlet pressure of 17 bar, flow 175 dm3/sec (371 scfm), and a start point at 6 dm3/sec. This combination supports stable micro fog lubrication across a wide operating range, maintaining a consistent oil/air ratio even as flow varies. The result is reliable lubrication for general pneumatic applications with predictable actuation and reduced oil waste.
Yes. The micro fog approach is designed for long and more complex pipework, delivering a fine mist that travels efficiently through extended runs. The aluminium body and closed bowl help resist contamination and corrosion in harsh environments, while the modular yoke option and service kit support scalable installations across multiple production lines, maintaining consistent lubrication throughout.
Certification and regulatory requirements vary by region. Pneumatic lubrication components are commonly aligned with CE marking and region-specific safety standards; however, verify local approvals for your facility. The L68M-NNP-ERN is designed to meet typical industrial expectations for reliability and documentation, with installation guides and service kits that support compliant maintenance practices.
To maximize uptime and minimize lifecycle costs, use the L68M-KIT service kit and the documented installation guide for periodic maintenance. The modular yoke system (Y68A-6GN-N1N/N2N) and optional bowl sizes support easy upgrades or capacity adjustments without replacing the entire unit. Regular checks of the flow sensor and elastomer seals help ensure consistent lubrication and extended service intervals.
