Quick Summary

Norgren L73C-4GP-QPN Excelon oil fog lubricator delivers precise lubrication for pneumatic systems in automation. Many operators struggle to maintain a stable oil-to-air ratio across varying flow conditions, risking cylinder wear and inconsistent tool performance. Excelon supports inline or modular installation and uses a flow sensor to maintain a nearly constant oil/air ratio over a wide range of flows. This approach aligns with CE marking and IP-rated configurations typical in modern factories, helping you meet regulatory requirements with less complexity. With rugged aluminium bodies and a polycarbonate bowl, you gain reliability and lower maintenance costs in challenging environments.

Inline or modular installation is a defining feature of the L73C-4GP-QPN, enabling rapid deployment across single machines or entire lines. This flexibility reduces install time and minimizes pipework complexity, which translates to lower commissioning costs and easier future reconfiguration in expanding plants. Heavier lubrication is delivered by the oil fog approach, making it ideal for large bore cylinders, air motors, and high-demand pneumatic tools where standard misting falls short. The lubricator fog with controlled flow means longer seal life and reduced maintenance intervals in demanding cycles. Flow sensor maintains a nearly constant oil-to-air ratio across 38 dm3/s maximum flow, supporting consistent performance from start to peak demand. Start point at 0.71 dm3/s ensures lubrication begins quickly after startup, improving response times in automated cycles. Robust materials, including an aluminium body and polycarbonate bowl with a guard, withstand industrial environments while maintaining visibility and safe operation. Manual drain allows straightforward maintenance, while the guard protects the bowl and reduces contamination risk. Compatibility with standard G1/2 ports and 10 bar maximum inlet pressure ensures this unit fits typical factory air networks and aligns with downstream components like valves and actuators.

FAQs

Install the L73C-4GP-QPN either inline or as a modular add-on to existing air lines. Connect the G1/2 port to the respective supply and downstream components, ensure the bowl guard is in place, and verify a clean, dry air supply. The unit’s manual drain should be accessible for periodic maintenance, and the guard helps protect the polycarbonate bowl in busy production environments.
Key specs include compressed air as the medium, operating temperature from -34 to 50 °C (-30 to 122 °F), port size G1/2, manual drain, maximum inlet pressure of 10 bar, oil fog lubricator type, flow up to 38 dm3/sec (81 scfm), and a start point of 0.71 dm3/sec. Construction uses an aluminium body and a polycarbonate bowl with elastomer seals.
Yes. The Excelon L73C-4GP-QPN uses oil fog lubrication designed for heavier lubrication over short runs, which is beneficial for large bore cylinders, air motors, and high-demand pneumatic tools. Its flow characteristics and robust materials help maintain lubrication efficiency under demanding cycling and stop-start operation typical in automation cells.
Maintenance is straightforward: use the manual drain for periodic oil bleed and bowl cleaning, replace the guardable bowl if damaged, and inspect the flow sensor relationship with the oil mist to ensure consistent ratios. Regular checks for leaks, connector integrity, and cleanliness of air lines will help preserve performance and extend service life.
