Norgren L73M-3GP-ETN Excelon Micro Fog Lubricator - Closed
Part Number: L73M-3GP-ETN
Quick Summary
Norgren L73M-3GP-ETN Excelon Micro Fog Lubricator provides precise inline lubrication for general purpose pneumatic systems. Operators often struggle with inconsistent lubrication, spillage, and downtime from failed components. Key considerations include CE conformity for Europe, rugged design, and safe operation across typical industrial environments. Designed for in-line or modular installation, it reduces oil waste while improving actuator reliability on long pipe runs. The micro fog flow sensor maintains a near-constant oil/air ratio across wide flows, supporting consistent performance. These capabilities translate to lower maintenance costs, higher uptime, and measurable process efficiency for factory automation and packaging lines.

FAQs
Install the lubricator at a suitable point in the air line, ensuring the G3/8 port matches the upstream feed. Mount in-line or in a modular block per the Excelon installation guide, orient for gravity-assisted bowl drainage, and connect to a clean, dry compressed air supply. Use the CAD and installation documents to verify alignment and fittings before commissioning.
The micro fog design delivers a fine mist that minimizes lubricant usage while preserving adequate oiling of downstream actuators. With a flow of up to 38 dm3/sec (81 scfm) and a start point around 0.71 dm3/sec, the system maintains a near-constant oil/air ratio across a wide flow range, improving repeatability and reducing wear in general-purpose circuits.
Yes. The Excelon L73M-3GP-ETN is designed for in-line or modular installation and excels in long or complex pipework where consistent lubrication is critical. The closed bowl minimizes spills and the aluminium body provides durability, making it well-suited for continuous operation in automation and packaging lines.
Procurement should consider CE conformity for European markets and adherence to standard industrial safety practices. For rugged or regulated environments, confirm enclosure protection and any SIL-related considerations with your spec sheet and the installation guide. Always verify the exact certification status with the supplier documentation before purchase.
The closed bowl design reduces oil spillage and contamination, lowering cleaning and maintenance needs. Precise micro fog dosing reduces lubricant consumption, cutting operating costs. In-line or modular installation minimizes downtime during upgrades, and the robust materials support long service life, delivering measurable return on investment through improved uptime and reduced part wear in automation systems.
