Norgren L74M-3GP-EAN Excelon Micro Fog Lubricator - G3/8
Part Number: L74M-3GP-EAN
Quick Summary
Norgren L74M-3GP-EAN Excelon micro fog lubricator delivers precise oil mist for general purpose pneumatic systems. In compact manifolds and long pipe runs, maintaining a stable oil-to-air ratio can be challenging and lead to uneven lubrication. Key certifications to verify in the datasheet include CE conformity, IP ratings, and SIL safety considerations. Designed for inline or modular installation, this lubricator integrates with Excelon 73/74-series components for scalable automation and reduced maintenance.

FAQs
The Excelon design supports both inline installations and modular mounting, allowing you to place the lubricator directly in the line or as part of a modular block. This flexibility reduces piping complexity, speeds up commissioning, and simplifies future expansions while maintaining a consistent lubrication point for multiple actuators.
The L74M-3GP-EAN operates from −34 to 80 °C (−30 to 176 °F) and handles up to 17 bar maximum inlet pressure. These ranges suit a wide variety of shop floor environments and seasonal temperature swings, ensuring stable lubrication without ad hoc adjustments.
This unit delivers micro fog lubrication that creates a finer, more uniform oil mist, supporting a nearly constant oil-to-air ratio across a broad flow range. Combined with a compact aluminium body and closed-bowl design, it reduces oil carryover and contamination, improving actuator life and system efficiency.
Yes, the L74M-KIT service kit is available for routine maintenance, seal replacements, and performance restoration. Regular checks should focus on bowl integrity, level indication, and flow consistency. The closed bowl minimizes contamination, while the 1 L aluminium bowl supports long service intervals in standard industrial environments.
