Norgren L73M-4GP-ETN Excelon micro fog lubricator - G1/2
Part Number: L73M-4GP-ETN
Quick Summary
The Excelon L73M-4GP-ETN micro fog lubricator provides precise oil mist for general pneumatic systems in automation. Professionals often struggle with uneven lubrication that accelerates wear, causes deposits, and increases maintenance. Certifications such as CE safety, SIL reliability, and robust enclosure protection are common expectations—verify the L73M-4GP-ETN’s status with Norgren. Inline installation options and a compact module design support both new builds and upgrades, while a closed-bowl design minimizes oil aerosol in work areas. The aluminium body with a polycarbonate bowl offers durability in challenging environments, and the micro fog nozzle supports long and complex piping. By optimizing oil/air balance across variable flows, it helps reduce waste and downtime, streamlining maintenance budgets.

FAQs
The L73M-4GP-ETN supports in-line and modular installation, enabling flexible integration with standard pneumatic lines. It uses a G1/2 port and a compact form factor for easy mounting in existing enclosures or on manifolds. This compatibility reduces retrofit complexity and shortens commissioning time, making it suitable for both new builds and upgrades in automation cells.
Micro fog lubrication provides a fine oil mist that helps maintain a nearly constant oil/air ratio across a wide flow range. With a maximum inlet of 10 bar and a start flow of 0.71 dm3/sec, the unit maintains stable lubrication from low to high demand. This leads to reduced wear, lower lubricant consumption, and more predictable performance on long, complex piping runs.
Yes. The Excelon L73M-4GP-ETN is designed for general pneumatic applications and automation lines, including long or intricate pipework. Its aluminium body and closed-bowl design support robust operation, while the G1/2 port and 38 dm3/sec flow capacity enable compatibility with standard plant air systems. It is well-suited for assemblies, pick-and-place, and conveying tasks.
Certifications are not listed in the provided data. For regulatory compliance, verify with Norgren or authorized distributors about CE, SIL, and IP ratings for this model. In practice, confirm applicable regional certifications and safety integrity requirements before installation to ensure compliant operation within your facility.
The closed-bowl design reduces oil mist spread, lowering housekeeping and exposure risks, while the flow sensor helps maintain a stable oil/air ratio, reducing lubricant waste. In typical production lines, this translates to longer service intervals, lower lubricant costs, and fewer unplanned downtime events—contributing to a favorable ROI through improved process reliability and maintenance efficiency.
