Norgren L72C-2GP-QDN Excelon Oil Fog Lubricator - G1/4
Part Number: L72C-2GP-QDN
Quick Summary
Norgren L72C-2GP-QDN Excelon oil fog lubricator provides precise oil-in-air lubrication for pneumatic cylinders, air motors, and tools. Many lines suffer from inconsistent oil-air ratios and maintenance complexity, leading to performance variability and downtime. The Excelon L72C series supports inline or modular installation, robust metal bowls, and a flow sensor that maintains a steady oil-air mix over a wide range of flows. With a compact G1/4 port and a manual drain, it integrates easily into existing piping and control schemes without disrupting line layout. Always verify applicable certifications such as CE and IP ratings on the official datasheet to ensure compliance in your facility. Engineers will benefit from CAD data, downloadable datasheets, and predictable lubrication performance under temperatures from -34 to 65 °C.

FAQs
Yes. The L72C-2GP-QDN is designed for both inline and modular installation, letting you drop it into existing piping with minimal disruption. The G1/4 port size and compatible mounting pattern simplify replacement or expansion in compact manifolds, while the in-line configuration supports scalable lubrication networks. This flexibility reduces installation time and hardware costs on retrofit projects.
Key performance specs for the L72C-2GP-QDN include a flow of 24 dm3/sec (51 scfm), a start point of 0.47 dm3/sec, and a maximum inlet pressure of 17 bar. Together with oil fog lubrication, these figures enable a nearly constant oil-air ratio across a broad range of flows, ensuring reliable misting for pneumatic tools and cylinders.
Yes, the Excelon design targets heavier lubrication needs over short runs. Oil fog delivery provides higher lubricant content where large bore cylinders, air motors, or air tools require robust smoothness. The unit’s flow characteristics and stable oil-air ratio help minimize wear, improve tool life, and reduce lubrication maintenance intervals in manufacturing lines.
Maintenance is simplified by the manual drain, and you can download CAD, CAD STEP, Datasheet PDF, and Installation Guide from the product downloads section for correct installation. Having these files on hand speeds up commissioning, reduces design errors, and supports compliant change management on plant upgrades.
The unit operates from -34 to 65 °C and supports up to 17 bar inlet pressure, making it suitable for varied plant environments. Ensure correct fittings and mountings, verify the G1/4 port compatibility, and reference the datasheet or installation guide for wiring and drainage procedures to maintain performance.
