Norgren L74M-3GP-EDN Excelon Micro Fog Lubricator - G3/8
Part Number: L74M-3GP-EDN
Quick Summary
Norgren L74M-3GP-EDN Excelon micro fog lubricator enables precise oil‑air lubrication for general pneumatic systems. Inline or modular installation can be time-consuming without a compact, robust solution designed for challenging pipe layouts. For critical safety and compliance, verify model-specific certifications such as SIL, CE, and IP ratings directly with Norgren. By delivering a nearly constant oil‑to‑air ratio and a fine mist over long runs, this lubricator reduces maintenance downtime while improving process consistency and machine uptime. Its aluminium body and closed‑bowl design support durable operation in harsh environments and simplify servicing, making it a reliable choice for automation cells and manufacturing lines.

Excelon design allows inline or modular installation, enabling flexible integration in tight spaces. The business impact is faster project completion and scalable deployment across multiple lines, reducing installation costs and downtime. This is ideal for general pneumatic systems in manufacturing cells, packaging lines, and automation equipment.Micro fog lubrication delivers a fine mist optimized for long piping and complex layouts, improving lubrication efficiency and reducing oil consumption. In practice, this means more consistent performance across varying pressures and demand, with fewer adjustments required during setup.Flow sensor architecture contributes to a near-constant oil/air ratio across wide flow ranges—critical for process stability on lines with changing demand (73 dm3/sec, 155 scfm at full flow; start point 0.94 dm3/sec).Closed bowl design protects the lubricant from contaminants and minimizes maintenance. This supports clean operation in dirty environments and simplifies drainage and servicing.Aluminium body and bowl provide rugged durability with light weight, while chloroprene and nitrile elastomers resist oil exposure. Operating temperature from -34 to 80 °C and a maximum inlet pressure of 17 bar ensure compatibility with most industrial compressed air installations.Compatibility with Excelon accessories such as the 3/2 modular shut-off valve and porting blocks simplifies system architecture. The L74M-KIT service kit and mounting options like the Universal Bracket keep maintenance predictable and downtime low.

FAQs
The L74M-3GP-EDN supports both inline and modular installation, enabling flexible mounting in tight spaces and across multiple automation cells. It pairs with accessories such as the Universal Bracket and Quikclamp systems to accelerate installation, simplify servicing, and scale lubrication across production lines.
The built-in flow sensor maintains a nearly constant oil-to-air ratio across a broad range of flows, supporting stable lubrication as demand shifts. With a full-flow specification of 73 dm3/sec (155 scfm) and a defined start point of 0.94 dm3/sec, the system delivers consistent performance without frequent recalibration.
Yes. The Excelon micro fog design produces a fine mist optimized for longer runs and more complex pipe networks. This reduces oil usage while maintaining effective lubrication, helping sustain performance on extended pneumatic lines without increasing maintenance intervals.
Maintenance is supported by the L74M-KIT service kit, which includes essential seals and parts for routine servicing. Compatibility with mounting accessories like the 4324-50 Universal Bracket and Quikclamps further simplifies periodic servicing and minimizes downtime during component replacement.
The unit features an aluminium body and bowl with elastomers in chloroprene and nitrile. It operates from -34 to 80 °C and tolerates up to 17 bar maximum inlet pressure, making it suitable for a wide range of industrial compressed-air environments while providing durable protection against typical shop-floor contaminants.
