Norgren L74C-3GP-EDQ Excelon oil fog lubricator - G3/8
Part Number: L74C-3GP-EDQ
Quick Summary
Norgren L74C-3GP-EDQ Excelon oil fog lubricator provides precise inline lubrication for heavy pneumatic cycles. This minimizes inconsistent oil delivery that can lead to tool wear, poor cycle repeatability, and unplanned downtime in automation lines. When selecting lubrication components, verify CE compliance, SIL safety considerations, and IP-rated enclosures to ensure safe, reliable operation across harsh environments. In practice, this modular Excelon solution supports inline or modular installation and a clean closed-bowl design, delivering dependable performance with simple maintenance.

Excelon in-line or modular installation enables rapid deployment and scalable system architectures. This flexibility reduces integration time on new lines and simplifies retrofits in existing equipment, delivering a measurable reduction in installation costs. Typical applications include inline lubrication of large-bore cylinders, air motors, and heavy pneumatic tools, where modular mounting saves space and simplifies maintenance. Oil fog lubrication is ideal when higher lubrication is required over short distances. The L74C-3GP-EDQ maintains a nearly constant oil-to-air ratio across a wide flow range, ensuring consistent performance from start point to peak demand. In practice, this improves tool life and reproducibility in high-cycle automation. With a maximum inlet pressure of 17 bar and a flow of 91 dm3/s (193 scfm), the unit supports demanding lines, while the start point of 0.94 dm3/s allows smooth ramp-up and minimizes oil waste. The aluminium body and bowl provide robust, corrosion-resistant construction, and the closed-bowl drain reduces contamination and spill risk, facilitating easier maintenance. Designed to integrate with Excelon modular accessories such as shut-off valves, porting blocks, brackets, clamps, and mounts, this lubricator enables rapid installation and secure field service, improving overall line uptime and reliability.

FAQs
The L74C-3GP-EDQ supports both in-line and modular installations thanks to its Excelon design and compact aluminium body. It uses a G3/8 port and closed-bowl configuration, with a quick-fill nipple for easy service. For modular systems, pair it with the Excelon 3/2 shut-off valve (T74T-3GA-P1N) and compatible porting blocks for a tidy, leak-free setup.
Key specifications include medium as compressed air, port size G3/8, drain type closed bowl, maximum inlet pressure of 17 bar, flow of 91 dm3/sec (193 scfm), start point of 0.94 dm3/sec, and construction from aluminium for body and bowl. Elastomers are chloroprene and nitrile. These specs support reliable lubrication across demanding automation cycles.
Yes. Oil fog lubrication is ideal for heavier lubrication over short distances, such as large bore cylinders, air motors, and air tools. The Excelon design provides inline reliability, while the closed-bowl and aluminium construction offer durability in harsh environments. Typical installations benefit from consistent lubrication, reduced tool wear, and improved cycle consistency.
Verify relevant standards for your application, including CE marking and appropriate IP or safety certifications for your environment. Also confirm environmental compatibility with the operating temperature range (-34 to 80 °C) and the elastomer seals (chloroprene, nitrile). When integrating, check compatibility with accessories like T74T-3GA-P1N and porting blocks to ensure regulatory and leak-free performance.
Maintenance is streamlined by the closed-bowl design and quick-fill nipple, plus availability of the L74M service kit for rapid servicing. The Flow sensor helps maintain a stable oil/air ratio, reducing waste and tool wear. The L74C-3GP-EDQ’s compatibility with Excelon modular accessories also minimizes downtime during upgrades and expansions, improving overall ROI on automated lines.
