Norgren L73M-3GP-EPN Micro Fog Lubricator - Closed G3/8
Part Number: L73M-3GP-EPN
Quick Summary
The L73M-3GP-EPN Excelon micro fog lubricator provides precise oil mist for general pneumatic systems. Engineers frequently contend with long pipe runs and fluctuating flows that yield inconsistent lubrication and elevated maintenance costs. This design emphasizes safety and reliability with features such as a closed bowl, G3/8 port size, and an aluminium body built for harsh environments. Inline or modular installation supports flexible deployment across conveyors, robotics, and automated test rigs while maintaining a stable oil–air ratio. The combination of tiny spray droplets, robust construction, and built‑in flow sensing helps reduce lubricant waste, extend tool life, and lower total cost of ownership.

FAQs
For inline or modular installations, use standard G3/8 fittings and compatible piping. The unit supports inline mounting for quick integration into existing lines and modular configurations for future expansions. Ensure the bowl is closed and the drain is unobstructed to maintain the micro fog output and oil/air ratio across the system.
Key specs include a maximum inlet pressure of 10 bar, flow of up to 38 dm3/sec (81 scfm), and a start point of 0.71 dm3/sec. The integrated flow sensor maintains a nearly constant oil/air ratio over a wide range of flows, improving lubrication consistency and reducing oil waste even on long or complex piping runs.
Ideal for general pneumatic systems across automation, conveyors, packaging, and robotics. Its micro fog output is well-suited for long pipe networks and complex installations where precise lubrication and stable output are critical for consistent tool life and reduced maintenance in demanding environments.
Certification needs vary by region and application. Look for components that meet your local safety and environmental regulations, with attention to enclosure protection, material compatibility, and documented conformity in supplier datasheets. For critical safety systems, verify integration with existing SIL, CE, or IP-related requirements as applicable to your facility.
Regular inspection of the closed bowl, seals, and fittings is recommended to prevent leaks and contamination. Monitor oil level and output consistency with the flow sensor, and schedule periodic replacement of elastomer seals. The durable aluminium body and fixed-output micro fog design reduce waste, extend tool life, and lower operating costs over the life of the system.
