Norgren L84C-4GP-EDN Excelon Plus Oil Fog Lubricator - G1/2
Part Number: L84C-4GP-EDN
Quick Summary
Excelon Plus oil fog lubricator is designed to deliver precise lubrication for pneumatic systems and large bore cylinders. Engineers often struggle with inconsistent oil metering that leads to wear, maintenance downtime, and unpredictable performance. The L84C-4GP-EDN combines inline or modular installation, a closed-bowl reservoir, and reliable oil fog delivery to support heavier lubrication over short distances. In addition to standard compatibility with Excelon Plus mounting options, this unit aligns with common compliance expectations such as CE conformity and robust enclosure practices. The result is a compact, low-maintenance solution that reduces lubricant waste while improving line uptime and overall equipment effectiveness in auto- mation and manufacturing environments.

FAQs
The L84C-4GP-EDN supports both inline and modular installation, enabling flexible integration into existing piping or new setups. It is compatible with Excelon Plus mounting kits including 840024-50KIT for general mounting and 840014-51/52KIT Quikclamp assemblies for fast, tool-free mounting. This versatility reduces installation time and minimizes system downtime during retrofits or new line builds.
This unit delivers oil fog lubrication with a documented flow of 91 dm3/sec (193 scfm) and a start point of 0.94 dm3/sec, suitable for heavier lubrication over short distances. The flow sensor helps maintain a nearly constant oil/air ratio across a wide range of flows, improving consistency and reducing lubricant waste in high-demand applications.
Yes. The lubricator is designed to integrate with Excelon Plus mounting accessories, including the 840024-50KIT General Mounting Bracket and Quikclamp kits 840014-51KIT and 840014-52KIT, enabling secure, vibration-resistant installations in compact spaces or on modular manifolds.
The closed-bowl design helps contain lubricant and contaminants, while the bowl features a double safety lock for enhanced shutdown safety and spill prevention. For tuning and refilling, use compatible quick-fill components such as 18-011-024. Regular checks should confirm the integrity of the bowl seal and the absence of blockages in the flow path.
Expected value includes improved uptime due to more reliable oil metering, reduced wear on cylinders and tools from consistent lubrication, and lower maintenance costs from modular mounting and compact, lightweight design. The integrated flow control and robust materials support long life in demanding industrial environments.
