Norgren L73C-4AP-EDN Excelon oil fog lubricator - Closed bowl
Part Number: L73C-4AP-EDN
Quick Summary
The L73C-4AP-EDN Excelon oil fog lubricator supplies controlled lubrication for pneumatic systems used in inline or modular automation setups. Inconsistent oil delivery and maintenance costs are common pain points that drain uptime and raise operating costs. Certification context for safety-critical installations often includes CE compliance and SIL-ready integration, with IP-rated variants available across the Excelon range; always confirm current documentation. This solution supports industrial automation goals with a compact aluminium body and a reliable oil fog approach, while offering easy installation and compatibility with a 1/2" PTF port. The flow sensor maintains a nearly constant oil/air ratio across a wide range of flows, enhancing predictability in large bore cylinders, air motors, and tooling applications.

Excelon Plus oil fog lubricator, 1/2" PTF, Metal bowl closed
The Excelon L73C-4AP-EDN offers inline or modular installation, enabling rapid deployment across multiple zones of a production line and reducing wiring and plumbing complexity. An aluminium body and closed-bowl design deliver robust durability in busy shop floors while minimizing contamination risk, leading to lower maintenance cycles and longer service life. With an oil fog lubrication approach, this unit supports heavier lubrication over short distances, ideal for large bore cylinders, air motors, and air tools, and the integrated flow sensor helps sustain a stable oil-to-air ratio across varying flows for consistent performance. A 1/2" PTF port and compatible mounting options streamline retrofit projects and new builds alike, while CAD and installation guidance support quicker commissioning. The L73C-4AP-EDN also aligns with common automation workflows, reducing lifecycle costs and improving reliability in automated lines.

FAQs
The L73C-4AP-EDN is designed for both inline and modular installation within compressed air systems. This flexibility supports scalable automation, enabling you to extend lubrication coverage across multiple stations without reworking existing plumbing. The 1/2" PTF port standardizes connections, while the aluminium body and closed-bowl design simplify mounting and maintenance, reducing downtime during expansion or reconfigurations.
Important specs include a 1/2" PTF port, maximum inlet pressure of 17 bar, oil fog lubrication, flow rating of 38 dm3/sec (81 scfm), and a start flow of 0.71 dm3/sec. Operating temperature ranges from -34 to 80 °C (-30 to 176 °F). The device uses aluminium for body and bowl plus elastomer materials (chloroprene and nitrile) to balance durability with sealing performance in typical factory environments.
Yes. The Excelon design emphasizes oil fog lubrication that is effective over short distances, which is ideal for larger bore cylinders, air motors, and air tools. The flow sensor ensures a stable oil/air ratio across varying loads, helping maintain consistent lubrication where tool life and performance are most sensitive to lubricant quantity and timing.
Certification data is not explicitly listed in the provided specification. For safety-critical or regulated environments, verify CE compliance and any region-specific approvals with the supplier documentation. SIL-ready integration and IP-rated variants are commonly available in Excelon products; confirm the exact variant and current certificates for your installation and risk assessment.
The closed-bowl design reduces contamination ingress, while the oil fog approach lowers lubricant consumption and waste. With a stable oil/air ratio across flow ranges, the lubricator supports predictable tool wear and fewer re-lubrication events. Combined with inline/modular installation and accessible documentation (CAD, datasheet, and installation guide), the unit helps shorten maintenance windows and improve line uptime.
