Norgren L73C-3GP-EPN Excelon oil fog lubricator - G3/8
Part Number: L73C-3GP-EPN
Quick Summary
L73C-3GP-EPN oil fog lubricator is designed to reliably lubricate compressed air lines in automated pneumatic systems. Too often, inconsistent lubrication leads to faster wear, higher maintenance costs, and unpredictable production downtime. Certification details, including CE marking and IP ratings, are provided in the Datasheet; please consult the linked PDF for official ratings and installation guidelines. This Excelon design supports inline or modular installation, offering a scalable solution for growing automation needs. By stabilizing the oil-to-air ratio across varying flows, it helps protect cylinders, motors, and tools from uneven wear, reducing consumable use and extending service intervals. In practice, engineers gain predictable performance and procurement teams achieve lower total cost of ownership through standardized replacement parts.

Inline or modular installation flexibility enables quick retrofits and scalable system architecture, reducing retrofit downtime and enabling phased upgrades in existing lines. This translates into faster changeovers, lower project risk, and a consistent platform across production cells, supporting lean manufacturing goals. The Excelon design is ideal for tight spaces and evolving layouts where a compact, modular lubrication point is essential for uptime. Oil fog lubrication is suited for heavier lubrication needs over short distances, providing reliable protection for large bore cylinders, air motors, and air tools while minimizing oil carryover and valve wear. The integrated flow sensor maintains a nearly constant oil-to-air ratio across a wide flow range, delivering predictable performance, reduced waste, and lower consumable costs in variable-demand systems. Robust materials (aluminium body, polycarbonate bowl) with a guard-ready design deliver long service life in industrial environments, while the G3/8 port and 10 bar maximum inlet pressure simplify installation in existing lines. This combination supports inline installation, modular upgrades, and easy compatibility with current automation blocks, accelerating commissioning and reducing total cost of ownership.

FAQs
This model supports inline or modular installation. Start by aligning the G3/8 port with the supplier’s fittings, mount using appropriate hardware to minimize vibration, and attach the closed bowl guard. Connect to the compressed air line and verify proper oil fog feeding. For orientation and detailed installation steps, refer to the CAD download and the datasheet in the Downloads section.
Operating temperature range is -34 to 50 °C (-30 to 122 °F). Maximum inlet pressure is 10 bar. Ensure system pressure does not exceed 10 bar and that ambient conditions do not drive the unit outside its rated temperature range for optimal performance and safety.
Yes. The Excelon oil fog lubricator is intended for heavier lubrication over short distances, making it suitable for large bore cylinders, air motors, and air tools. Typical flow and start point (38 dm3/sec and 0.71 dm3/sec) support reliable lubrication at varying demand levels in automated lines.
Certification details such as CE marking or IP ratings are not listed in the provided data. Please consult the Datasheet (PDF) linked in the Downloads section for official ratings and compliance information.
The design supports inline or modular installation, reducing downtime during upgrades. The flow sensor maintains a consistent oil/air ratio, lowering oil consumption and improving lubrication reliability. Together, these features translate to lower maintenance costs, longer component life, and a more predictable total cost of ownership in automated production environments.
