Norgren L73M-4GP-QDN Micro Fog Lubricator - Excelon
Part Number: L73M-4GP-QDN
Quick Summary
Excelon micro fog lubricator delivers precise oil-air lubrication for general-purpose pneumatic systems in manufacturing environments. Engineers often face inconsistent lubrication that drives wear, increases maintenance needs, and risks unplanned downtime. While not all models carry explicit certifications in every data sheet, CE compliance, IP-rated enclosures, and SIL considerations are key benchmarks in modern automation components. With inline or modular installation and durable aluminum construction, this solution reduces installation complexity and lifecycle costs. The combination of micro fog delivery, a steady oil-to-air ratio, and a compact form factor supports reliable performance across long piping runs. Secondary benefits include flexible maintenance options and compatibility with standard G1/2 ports, streamlining integration into existing systems.

Inline or modular installation offers flexible deployment across varied line layouts. By enabling quick installation and straightforward relocation, it reduces commissioning time and wiring effort, lowering total installed costs. In practice, manufacturers operating multi-station automation lines gain a scalable lubrication solution where space is tight or access is limited. Micro fog lubrication delivers a fine mist that minimizes oil consumption while maintaining an almost constant oil-to-air ratio across a wide flow range, aided by an integrated flow sensor. This precise spray supports general-purpose pneumatic systems with long pipe runs and frequent position changes, reducing waste and ensuring consistent lubrication. Aluminium body and bowl offer robust durability and corrosion resistance in busy shop floors. This durability reduces replacement parts and downtime, supporting long service life in automotive, packaging, and general manufacturing environments. Operating range and compatibility shape installation planning. With a maximum inlet pressure of 17 bar and a G1/2 port, the unit aligns with common compressed-air distributions. The start point of 0.71 dm3/sec and rated flow of 38 dm3/sec enable predictable lubrication across varying load conditions. Maintenance convenience supports reliability. Manual drain simplifies condensate removal, reducing maintenance steps and potential contamination in the line. Designed to integrate with other Excelon components, it offers predictable compatibility with existing Norgren control strategies and standard fittings. Elastomer materials balance chemical resistance with seal integrity. Elastomer materials balance chemical resistance with seal integrity.
