Norgren L64M-NNP-EDN Micro fog lubricator - Closed bowl
Part Number: L64M-NNP-EDN
Quick Summary
Norgren L64M-NNP-EDN micro fog lubricator provides precise oil misting for general pneumatic systems. This compact device delivers consistent lubrication across piping networks, reducing wear and downtime. In the Olympian Plus family, modularity and a closed-bowl design help simplify installation and maintenance. For this model, verify datasheet for certifications and compliance such as CE conformity and relevant IP ratings; confirm SIL capabilities where required. The product leverages a plug‑in yoke concept and micro fog technology to support reliable lubrication in long pipework while maintaining a nearly constant oil/air ratio over a range of flows. By specifying this solution you gain predictable performance, lower consumption, and easier service in automation environments.

FAQs
The L64M-NNP-EDN uses a yoke-free port arrangement suitable for incorporating with standard Norgren mounting options. It supports compatible accessories like Yoke assemblies (Y64A-4GA-N2N, N3N, N1N) and the Wall Bracket 74504-50, enabling flexible placements on panels or frames. For retrofit projects, verify mounting footprint and ensure the provided accessories fit your enclosure and piping layout before final assembly.
Core performance specs include a medium of compressed air, maximum inlet pressure of 17 bar, flow of 72 dm3/sec (153 scfm), and a start point of 1.5 dm3/sec. The unit uses micro fog lubrication with a closed-bowl drain, a weight of 1.04 kg, and dimensions around 209 mm × 71 mm × 71 mm. Operating temperature ranges from -20 to 80 °C.
Yes, the L64M-NNP-EDN is designed for general pneumatic applications including long and complex pipework. It delivers micro fog lubrication that maintains a nearly constant oil/air ratio across a range of flows, reducing lubrication variance and wear along extended runs. Expect stable lubrication performance even as system demand varies during production cycles.
Maintenance should follow the installation guide and routine checks: inspect for signs of wear or leaks, ensure the bowl remains closed and clean, and confirm elastomer seals (nitrile rubber) are intact. Since the bowl is closed, follow the datasheet’s service intervals and replacement recommendations for the bowl assembly and seals based on oil quality and usage.
Mounting options include Yoke assemblies (Y64A-4GA-N2N, N3N, N1N) for plug‑in modularity and the Wall Bracket 74504-50 for secure surface mounting. These accessories support flexible installation in compact automation cells and facilitate alignment with upstream equipment, ensuring secure transport of oil mist and compatibility with your existing Norgren infrastructure.
