Norgren L73C-3GP-EDN Oil Fog Lubricator - G3/8
Part Number: L73C-3GP-EDN
Quick Summary
Norgren L73C-3GP-EDN oil fog lubricator provides inline lubrication for compressed air systems. A common challenge is maintaining a consistent oil-to-air ratio across flow changes, reducing cylinder wear and downtime. Industry-standard approvals often include CE certification, IP ratings, and SIL safety considerations—verify which apply to your installation. The Excelon design enables in-line or modular installation, supporting reliable oil fog lubrication for larger bore cylinders, air motors, and hand tools. This combination delivers predictable maintenance intervals, reduced parts wear, and improved system uptime, making it a strong fit for automation lines seeking cost-effective lubrication control.

FAQs
The L73C-3GP-EDN leverages the Excelon design to support both inline and modular installation. This dual approach enables quick deployment on existing lines or new builds with minimal downstream disruption. Its G3/8 port size aligns with common pneumatic hardware, simplifying retrofits and enabling scalable expansions across automation cells.
Key specifications include a flow capacity of 38 dm3/sec (81 scfm), a start point of 0.71 dm3/sec, and a maximum inlet pressure of 17 bar. It uses oil fog lubrication and is intended for compressed air as the working medium. These metrics support consistent lubrication for varied demand in automated lines and tooling.
Yes. The Excelon design provides heavier lubrication over short distances, which is ideal for large bore cylinders, air motors, and air tools. The aluminium body and closed-bowl design support reliable operation in demanding environments, helping to extend tool life and reduce maintenance frequency on high-load applications.
The provided data does not list specific certifications. In practice, engineers should verify applicable standards for their region, including CE, IP ratings, and SIL considerations as required by the installation. Always confirm with the supplier or the local authority having jurisdiction before commissioning.
By delivering a stable oil-to-air ratio and enabling inline or modular installation, the L73C-3GP-EDN reduces lubrication-related downtime and wear. The durable aluminium construction and safe closed-bowl design minimize spill risks, while the documented flow and pressure specs support accurate sizing and maintenance planning, improving uptime and lowering total cost of ownership over the equipment lifecycle.
