Norgren L73M-3AP-QPN Excelon Micro Fog Lubricator - 3/8\" PTF
Part Number: L73M-3AP-QPN
Quick Summary
Norgren L73M-3AP-QPN Excelon micro fog lubricator provides precise lubrication for general pneumatic systems. Engineers often struggle with maintaining a stable oil-to-air ratio across varying flow conditions, leading to inconsistent lubrication and maintenance delays. This design uses an integrated flow sensor to keep a nearly constant oil/air ratio over a wide range of flows, while the aluminium body and polycarbonate bowl with guard reduce wear and spill risk. Designed for inline or modular installation, it simplifies integration with 3/8\" PTF ports and manual drain for easy servicing, improving reliability and uptime across factory automation setups. This reduces total cost of lubrication by stabilizing performance and lowering maintenance time.

Excelon Plus micro fog lubricator, 3/8" PTF, Guarded plastic bowl closed
Excelon’s inline and modular installation capability allows flexible deployment across compact or retrofit projects, reducing installation time and enabling quick scale-up in production lines. The flow sensor maintains a near-constant oil/air ratio over a wide flow range, delivering predictable lubrication and minimizing oil waste, which translates to lower operating costs and improved machine uptime in general pneumatic applications. Aluminium body construction paired with a polycarbonate bowl and guard delivers robust durability and spill resistance, supporting long-term reliability in busy manufacturing environments while simplifying service access. A guarded bowl and manual drain simplify maintenance tasks, preventing accidental spills and enabling quick condensate removal during routine servicing, which reduces downtime and extends system life in continuous operation contexts. With 3/8\" PTF ports, inline or modular installations stay compatible with standard pneumatic hardware, saving integration effort on retrofits and new lines alike.

FAQs
The L73M-3AP-QPN is designed for both inline and modular installation, enabling flexible mounting along standard air lines. Use the 3/8\" PTF port connections for direct piping, secure the aluminium body to a stable bracket, and attach the polycarbonate bowl with guard. The manual drain should remain accessible for condensate removal. Ensure proper air supply, tighten fittings to spec, and verify there are no leaks after installation.
Key specs include a 3/8\" PTF port size, aluminium body, polycarbonate bowl with guard, manual drain, maximum inlet pressure of 10 bar, operating temperature from -34 to 50 °C (-30 to 122 °F), flow capacity of 38 dm3/sec (81 scfm), and a starting flow point of 0.71 dm3/sec. The unit uses micro-fog lubrication to optimize oil usage and consistency across line pressures.
Yes. The Excelon micro fog lubricator is designed for general pneumatic applications and long pipework, offering inline or modular installation and a guard-equipped bowl for spill prevention. The flow sensor maintains stable lubrication across varying flow rates, making it well-suited for systems with fluctuating demands and extended piping runs where lubrication consistency is critical.
