Norgren L73M-3GP-QDN Excelon Micro Fog Lubricator - G3/8 Port
Part Number: L73M-3GP-QDN
Quick Summary
Norgren L73M-3GP-QDN Excelon micro fog lubricator provides precise oil mist delivery for general purpose pneumatic systems. End users often struggle with uneven lubrication along long or modular pipe runs, which can cause wear, reduced accuracy, and unplanned downtime. Designed to support CE safety considerations and SIL-ready integration, the unit uses a rugged aluminium body and standard G3/8 connections for dependable operation in harsh environments. Inline or modular mounting options simplify retrofits and serviceability. By delivering a controlled micro‑fog output and maintaining a consistent oil/air ratio, this lubricator helps reduce oil consumption, lower maintenance frequency, and boost overall line productivity in automation projects.

FAQs
The L73M-3GP-QDN supports both in-line and modular installation, enabling quick integration into existing layouts and easier retrofits in tight spaces. With a G3/8 port and a manual drain, it aligns with standard pneumatic piping, allowing straightforward connection to current systems and minimized downtime during upgrades.
Key performance figures include a flow of 38 dm3/sec (81 scfm), a start point at 0.71 dm3/sec, and a maximum inlet pressure of 17 bar. The medium is compressed air, and the device delivers micro fog lubrication with a stable oil/air ratio across varying flow demands, supporting consistent actuation and reduced wear.
Yes. The Excelon micro fog lubricator is designed for general purpose pneumatic systems and long or modular piping runs. Its precise micro fog output, combined with inline or modular mounting, ensures uniform lubrication across extended networks, improving machine life, reducing wear, and enhancing productivity in automation cells and manufacturing lines.
The unit is designed to meet CE safety standards and is SIL-ready for integration in safety-critical systems. Although installation details specify G3/8 connections and maintenance protocols, always confirm local regulatory requirements and supplier certifications for your specific installation and industry.
Maintenance benefits come from a durable aluminium body, a manual drain for easy servicing, and a flow sensor that maintains a nearly constant oil/air ratio, reducing oil consumption. The result is lower maintenance frequency, fewer consumables, and faster throughput during retrofits or expansions, delivering improved return on investment and reduced downtime in automated lines.
