IMI Norgren L72C-3GP-EDN Oil Fog Lubricator - Closed Bowl
Part Number: L72C-3GP-EDN
Quick Summary
IMI Norgren L72C-3GP-EDN oil fog lubricator is designed to deliver precise inline lubrication for pneumatic systems. This solution helps avoid erratic oil delivery that leads to stalling or accelerated wear on cylinders and tools. In the Excelon family, common standards include CE compliance and IP-rated protection, with SIL-capable performance in demanding installations. The design supports either inline or modular installation, enabling flexible layouts and fast commissioning. The metal bowl with liquid level indicator improves maintenance visibility while reducing unplanned downtime. With the oil fog approach, operators gain reliable lubrication over short distances, improving actuator life and providing more predictable performance for production lines.

Excelon Plus oil fog lubricator, G3/8, Metal bowl closed
Inline or modular installation is built into the Excelon L72C design, enabling rapid integration into existing lines and reducing install time. Business impact: faster project kick-offs and lower commissioning costs. Application: retrofit campaigns and new equipment where space or modularity constraints exist. The oil fog lubrication approach supports heavier lubrication over short distances, ideal for large bore cylinders, air motors, and air tools. This delivers improved wear resistance and extended service intervals, reducing maintenance frequency and downtime in high-use automation cells. Flow sensor technology maintains a nearly constant oil/air ratio across a wide flow range, ensuring stable lubrication, minimizing waste, and delivering predictable output even as system demand shifts. This translates to consistent performance, reduced consumable costs, and easier regulatory compliance across batch runs. The closed metal bowl with a liquid level indicator simplifies maintenance planning and minimizes spill risk, supporting cleaner, safer enclosures and better inventory control. Durable zinc body and bowl, with chloroprene and nitrile elastomer seals, deliver robust performance in factory air environments; G3/8 port size and 17 bar maximum inlet pressure broaden compatibility with common automation circuits. The Excelon range offers cross-compatibility within the L72C family, helping maintain spare-part consistency and reducing stocking complexity. Overall, this lubricator supports easier installation, lower lifecycle costs, and improved uptime for pneumatic tooling and actuation in demanding production lines.

FAQs
The L72C-3GP-EDN supports both inline and modular installation, enabling flexible mounting across retrofit projects or new lines. Use the G3/8 port to connect standard piping, and place the unit upstream of pneumatic tools or cylinders to ensure consistent lubrication. The modular approach reduces downtime during skids swaps and simplifies future expansions.
Key specs include flow of 24 dm3/sec (51 scfm), start point 0.47 dm3/sec, maximum inlet pressure 17 bar, and operating temperature range -34 to 65 °C. The unit uses oil fog lubrication, delivering a nearly constant oil/air ratio across a wide flow range to keep tools and cylinders properly lubricated without wasting oil.
Yes. The Excelon L72C design is intended for heavier lubrication over short distances, making it ideal for large bore cylinders, air motors, and high-demand air tools. The oil fog method provides sustained lubrication where traditional drip systems may falter, improving reliability and tool life in demanding applications.
The closed bowl design reduces spill risk and keeps contaminants out, while a liquid level indicator aids maintenance planning. Regular inspection of seals (chloroprene and nitrile elastomers) and bowl integrity is advised, along with periodic replacement of elastomer seals to prevent leakage and maintain lubrication accuracy in dynamic production environments.
L72C-3GP-EDN shares design language and mounting/port patterns with other L72C Excelon lubricators, such as the L82C-3GP-EDN. This compatibility simplifies part stocking, reduces spare-parts complexity, and allows easier scaling across multiple lines while maintaining consistent performance and maintenance practices.
