Norgren L72M-3GP-QLN Excelon Micro Fog Lubricator - G3/8
Part Number: L72M-3GP-QLN
Quick Summary
Norgren L72M-3GP-QLN Excelon micro fog lubricator provides precise lubrication for general purpose pneumatic systems. Engineers often grapple with inconsistent oil/air ratios across long, complex pipe networks. Designed for CE compliance and robust industrial use, this Excelon unit supports inline or modular mounting. The flow sensor maintains a nearly constant oil/air ratio across a wide range of flows, delivering predictable lubrication. That reliability translates into lower maintenance costs and fewer unplanned stops on general-purpose pneumatic lines. In inline configurations, installation is straightforward with G3/8 port size and a long plastic bowl, and the integrated micro-fog design supports in-line or modular mounting, aligning with lean manufacturing and OEM integration goals.

Excelon Plus micro fog lubricator, G3/8, Guarded plastic bowl closed
Excelon micro fog lubrication with an integrated flow sensor delivers precise, controllable lubrication for general purpose pneumatic systems. The flow sensor maintains a nearly constant oil/air ratio across a wide range of flows, reducing lubricant waste and protecting sensitive actuators. In practice this means fewer fouled lines and extended maintenance intervals on lines with long or complex pipework, improving uptime and predictability in manufacturing and packaging environments.Installation flexibility is a core advantage: inline or modular mounting supports existing layouts and ease of OEM integration. The G3/8 port size, manual drain, and long plastic bowl simplify installation and servicing, enabling preventive maintenance without disrupting production. This approach also reduces spare parts inventory and speeds up retrofits across multi-line facilities, delivering measurable capital efficiency.Durability comes from zinc body construction with a polycarbonate bowl and elastomer seals (chloroprene and nitrile) chosen for chemical resistance and wear tolerance. This combination stands up to typical factory air streams, oil mist, and temperature variations, while remaining lightweight for field maintenance. Engineers appreciate predictable performance and minimal environmental concerns thanks to robust materials selection.Operating range and performance are aligned for reliability: -34 to 50 °C, maximum inlet pressure 10 bar, and a micro fog output that supports 24 dm3/sec with a start point at 0.94 dm3/sec. The design keeps a stable lubrication patrol across the tube network, even as line speed changes. These specs translate into consistent actuator response and reduced variability in downstream sensors.Business value is clear: reduced downtime, lower lubricant waste, and easier maintenance translate to lower total cost of ownership. Compatibility with inline and modular configurations, plus access to CAD data, STEP models, and installation guides, accelerates project timelines. In practice, Excelon L72M-3GP-QLN supports scalable automation across plants.

FAQs
The L72M-3GP-QLN supports inline or modular mounting, with a G3/8 port and long plastic bowl. Installation is straightforward on air lines, and the manual drain simplifies maintenance. The included flow sensor helps align lubrication with flow, while the zinc body and polycarbonate bowl withstand industrial environments. A single unit can retrofit older systems without major redesign.
This Excelon lubricator delivers 24 dm3/sec flow with a start point at 0.94 dm3/sec and supports up to 10 bar inlet pressure. It uses micro fog lubrication for a fine mist, with G3/8 ports and a manual drain. The flow sensor maintains a near-constant oil/air ratio across a wide range of flows, improving predictability.
Yes. The Excelon micro fog approach is optimized for long, intricate piping, with fine mist ensuring even lubrication across distant points. Inline or modular installation supports scalable configurations, while the zinc body and polycarbonate bowl resist abrasion and chemical exposure. The device also reduces lubricant waste by maintaining stable ratios at variable flow.
The L72M-3GP-QLN is designed to meet CE compliance for general industrial use. For precise IP ratings or SIL compatibility, consult the datasheet and installation guide. Norgren provides installation resources to support compliance with machine safety standards, making it suitable for integration into standard pneumatic ecosystems while maintaining traceability and serviceability.
By delivering a constant oil/air ratio and precise micro fog lubrication, maintenance intervals lengthen and lubricant waste decreases, yielding lower operating costs. The flow sensor improves control across varied line speeds, reducing unplanned downtime. In OEM setups, inline/modular compatibility speeds up installation, supporting faster throughput and more reliable pneumatic performance.
