Norgren L74C-3GP-EDN Excelon Oil Fog Lubricator - G3/8
Part Number: L74C-3GP-EDN
Quick Summary
L74C-3GP-EDN oil fog lubricator provides precise lubrication for compressed air systems used with cylinders, air tools, and motors. Inconsistent lubrication and maintenance downtime can degrade performance and shorten tool life; this Excelon unit stabilizes the oil-to-air ratio across a wide flow range to keep actuators consistently lubricated. Certifications are not listed in the data, but Norgren Excelon products are designed for harsh industrial environments and are compatible with common European and global standards in compliant installations. The design supports in-line or modular installation, improving space utilization in control panels and machine frames. With a metal bowl, closed drain, and a G3/8 port, it delivers reliable lubrication where you need it most, reducing maintenance and waste.

Excelon Plus oil fog lubricator, G3/8, Metal bowl closed
Oil fog lubrication supports heavy lubrication over short distances, improving performance of large bore cylinders, air motors, and tools. The Excelon design allows in-line or modular installation, enabling flexible, space-efficient layouts in new builds or retrofits. A built-in flow sensor maintains a nearly constant oil/air ratio across a wide flow range, reducing oil waste and ensuring consistent tool life. Aluminum body and bowl provide robust, corrosion-resistant durability in demanding environments, while the metal bowl with liquid level indicator helps operators maintain proper lubrication levels. The closed-bowl drain minimizes contamination and leaks, protecting downstream equipment. Start point and flow values (0.94 dm3/sec start; 91 dm3/sec flow) support predictable performance, while compatibility with service kits like L74M-KIT simplifies maintenance and part supply.

FAQs
The L74C-3GP-EDN supports both inline and modular setups. For inline piping, connect to the G3/8 port using standard compression fittings and mount the unit with compatible brackets (for example, 4324-50 Universal Bracket). For modular configurations, pair with Excelon accessories such as the T74T-3GA-P1N shut-off valve to steer flow from a common manifold. Ensure the supply line remains within the 17 bar maximum inlet pressure and operating range.
Key performance specs include a maximum inlet pressure of 17 bar, flow capacity of 91 dm3/sec (193 scfm), and a start point of 0.94 dm3/sec. Operating temperature is -34 to 80 °C. These figures support reliable lubrication across varied loads, from small tools to larger cylinders, while maintaining a stable oil-to-air ratio.
Yes. The Excelon L74C-3GP-EDN is designed for heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and air tools. Its oil fog type delivers sufficient lubrication with a closed-bowl design that minimizes contamination in shared compressor lines.
The provided data does not list specific certifications. For compliant deployments, refer to the manufacturer guidance and local regulations. Norgren Excelon products are typically designed to meet common industrial standards, and integration in CE-marked or IP-rated systems is based on the overall equipment configuration and installation.
Maintenance is supported by the L74M-KIT service kit, designed for L74 series lubricators. Regular service reduces the risk of flow deviation and leaks, extending component life and lowering replacement costs. The combination of a robust aluminum body, closed bowl, and easy maintenance access shortens downtime during scheduled servicing.
