IMI Norgren L73C-4AP-QDN Oil Fog Lubricator - Excelon 1/2" PTF
Part Number: L73C-4AP-QDN
Quick Summary
Norgren L73C-4AP-QDN oil fog lubricator provides reliable inline lubrication for pneumatic cylinders and air tools. Operators often face inconsistent oil-to-air delivery that leads to premature wear and increased maintenance. While the data here does not list explicit certifications, the Excelon line is designed for robust industrial use and straightforward inline or modular installation. Verify compatibility with CE-like standards and ensure the appropriate IP rating in your application datasheet. This solution supports efficient lubrication management, predictable service life, and streamlined procurement for compressed air systems. Secondary benefits include compatibility with 1/2" port installations and clear operability in demanding environments.

Feature → Business Impact → Application: Excelon design enables in-line or modular installation, reducing integration time and enabling scalable lubrication across multiple stations in a single line, which lowers total installation costs and downtime for pneumatic systems. This aligns with applications in compact automation cells where space is at a premium. Feature → Consistent oil/air ratio via an integrated flow sensor, delivering near-constant lubrication across varying flows, improving tool life and reducing maintenance intervals. This is ideal for larger bore cylinders, air motors, and air tools where precise lubrication is critical to performance. Feature → Oil fog lubrication provides heavier lubrication over short distances, supporting high-load cycles and demanding tooling environments while maintaining a clean, controlled lubricant delivery. Feature → 1/2" PTF port, manual drain, and aluminium body/bowl deliver a durable, easy-to-service package that minimizes downtime and simplifies installation in retrofit and new-build projects. Feature → Operating range −34 to 80 °C (−30 to 176 °F) and maximum inlet pressure of 17 bar ensure suitability for varied plant climates and compressed air conditions, reducing the need for multiple SKUs. Feature → Start point at 0.71 dm3/sec with a flow of 38 dm3/sec (81 scfm) provides predictable performance metrics, aiding accurate parameter planning and process validation in production lines.

FAQs
The L73C-4AP-QDN supports inline installation or modular integration in compressed air lines via a 1/2" PTF port. Connect to the air line, secure the aluminium body and bowl, and attach the manual drain for maintenance access. The unit’s flow sensor helps regulate oil into the air stream, ensuring consistent lubrication without over- or under-saturation, which simplifies commissioning and reduces setup time.
Key specs include a maximum inlet pressure of 17 bar, working temperature range −34 to 80 °C, and oil fog lubrication. The device provides a start point of 0.71 dm3/sec with an overall flow of 38 dm3/sec (81 scfm). Material construction uses aluminium for body and bowl, offering durability in industrial environments and ease of maintenance.
Yes. The Excelon design targets heavier lubrication needs over short runs, making it appropriate for large bore cylinders, air motors, and certain air tools. The oil fog approach delivers sufficient lubricant concentration over short distances while maintaining a controlled oil-to-air ratio, which helps extend component life and reduce tool wear in demanding applications.
The provided data does not list specific certifications such as SIL, CE, or IP ratings. For regulatory compliance, consult the datasheet or contact the manufacturer to confirm CE marking, IP rating, and relevant safety certifications. Always verify certification status before deployment in regulated environments.
Maintenance benefits include a manual drain for straightforward servicing and an integrated flow sensor that sustains a stable oil/air ratio, reducing re-lubrication frequency. ROI considerations focus on longer tool life, reduced downtime, and fewer lubrication-related failures, which translate to lower maintenance costs and higher production uptime in automated lines.
