The micro fog lubrication capability uses a flow sensor to maintain a nearly constant oil-to-air ratio over a wide range of flows. This stability reduces oil waste and minimizes wear on actuators, delivering more predictable performance in general-purpose pneumatic circuits. In longer pipework, this technology translates to fewer maintenance events and lower life-cycle costs. Inline or modular installation with the Excelon L74M family simplifies retrofits and scaling. The closed-bowl design keeps lubricant contained, while the 1 L aluminium bowl supports longer intervals between service events. Operators can mount the unit inline or as part of a modular lubrication block without sacrificing access to level indicators. Port size G1/2, maximum inlet pressure of 17 bar, and an operating temperature range of -34 to 80 C make the L74M-4GP-EAN suitable for diverse environments. The rugged aluminium body and elastomer seals withstand industrial conditions, helping maintain consistent flow and reducing leak-related downtime. Materials selection aligns with durability and compatibility: aluminium body and bowl, chloroprene and nitrile elastomers, and the L74M service kit for straightforward maintenance. Accessories such as the Excelon shut-off valve and porting block simplify integration within the Excelon 73/74 ecosystem, enabling cohesive installation with fewer compatibility concerns. Performance metrics like starting flow at 0.94 dm3/sec and a rated flow of 73 dm3/sec (155 scfm) give engineers clear targets for lubrication needs. The micro fog output combined with precise control supports consistent performance under varying pneumatic loads, helping teams meet efficiency and compliance goals. From installation to maintenance, the L74M-4GP-EAN is designed for minimal downtime and straightforward servicing. The availability of a dedicated service kit (L74M-KIT) and compatible mounting options (Quikclamps, universal brackets) reduces total cost of ownership while preserving equipment uptime in automated plants. Real-world feedback from maintenance teams highlights the ease of inspection with the liquid level indicator, and the predictable fog output supports standardized lubrication plans across multiple machines.

FAQs
The L74M-4GP-EAN supports inline and modular installation within the Excelon ecosystem. It uses a G1/2 port and a 1 L aluminium bowl with a closed drain, allowing inline mounting or integration into a modular lubrication block. For best results, pair with the Excelon T74T-4GA-P1N shut-off valve and the 4316-50 porting block to route lubrication cleanly and simplify service access.
Key specs include flow up to 73 dm3/sec (155 scfm), a start point of 0.94 dm3/sec, and a maximum inlet pressure of 17 bar. The unit operates from -34 to 80 C and delivers micro fog lubrication for a nearly constant oil-to-air ratio across a broad flow range, ensuring consistent lubrication for general-purpose pneumatic systems.
Yes. The micro fog output maintains a nearly constant oil-to-air ratio across varying flows, ideal for long pipework where demand changes along the line. Inline or modular installation supports scalable lubrication, while the aluminium construction and closed bowl reduce maintenance during extended deployments.
European markets typically require CE-compliant hardware and reliable safety integration in pneumatic systems. While exact certifications may vary by region, the Excelon L74M family is designed to work within standard industrial safety and environmental guidelines; users should confirm applicable requirements with their systems integrator and Norgren data sheets.
Maintenance is simplified by the L74M-KIT service kit and the modular accessory ecosystem. The closed-bowl design reduces spills, while service intervals align with air quality and usage. Availability of mounting hardware such as Quikclamp and universal brackets supports quick replacement, minimizing downtime and prolonging equipment life.
