Norgren L74M-4AP-EDN Excelon micro fog lubricator - 1/2" PTF
Part Number: L74M-4AP-EDN
Quick Summary
Excelon micro fog lubricator delivers precise lubrication for general pneumatic systems used in manufacturing automation. Engineers often wrestle with inconsistent lubrication, oil mist drift, and maintenance-heavy bowls; this design reduces drift and mess while simplifying upkeep. The Excelon line is commonly built to meet CE marking and IP-rated environmental standards; verify the exact certifications on the datasheet for your application. Inline installation flexibility and modular mounting options support flexible deployment, while the micro fog flow maintains a near-constant oil-to-air ratio across a wide range of flows. These features translate to improved tool life, reduced maintenance, and predictable performance in demanding industrial environments.

Inline installation flexibility and modular mounting are built into the Excelon L74M-4AP-EDN, allowing effortless integration into new lines or retrofits. This capability reduces design time, minimizes piping complexity, and lowers interface costs across machines. The 1/2" PTF port and compatibility with mounting options such as the Universal Bracket and Quikclamp streamline installation in a wide range of lines. Micro fog lubrication, guided by an integrated flow sensor, maintains a near-constant oil-to-air ratio over a broad flow range. This improves lubrication consistency, cuts oil waste, and extends downstream component life in general purpose pneumatic systems. The technology shines on long or complex pipe runs where traditional lubricators struggle to deliver uniform mist. Closed bowl design minimizes oil exposure, spills, and contamination, supporting a cleaner work environment and lower maintenance. The aluminium body and bowl provide rugged durability for harsh shop-floor conditions, while the elastomer seals resist wear in demanding environments. A service kit L74M-KIT enables rapid field servicing to keep downtime to a minimum. With a 1/2" PTF port and maximum inlet pressure of 17 bar, the L74M-4AP-EDN fits broadly used shop-floor compressors and regulators. The porting compatibility supports reliable lubrication across general automation applications while preserving fast response and precise lubrication. Materials - Body and Bowl are aluminium with elastomer seals (chloroprene and nitrile), delivering reliable operation from -34 to 80 °C. Inline installation or modular mounting integrates smoothly with Excelon accessories such as porting blocks and shut-off valves, enabling tailored solutions for diverse lines. Flow of 73 dm3/sec (155 scfm) and a start point of 0.94 dm3/sec provide predictable starting and steady operation across changing loads. This makes it well-suited for general pneumatic automation, packaging, and machine tooling, delivering consistent lubrication in compact footprints and supporting long-term cost savings through reduced waste and maintenance.

FAQs
Yes. The L74M-4AP-EDN supports inline installation or a modular setup using Norgren Excelon accessories, enabling quick integration into existing lines or new assemblies. Its standard 1/2" PTF port and compatible mounting options streamline retrofits without extensive piping changes. For best results, pair with compatible porting blocks and mounting brackets such as the 4316-50 block and Quikclamp hardware as needed.
Key specs include a flow of 73 dm3/sec (155 scfm) and a start point of 0.94 dm3/sec. This ensures rapid startup and stable lubrication across a wide range of loads. The maximum inlet pressure is 17 bar, supporting typical factory air supplies and preventing over-pressure scenarios in general automation.
Ideal for general purpose pneumatic applications such as assembly lines, packaging equipment, and machining tooling. The micro fog approach provides a consistent oil mist over long pipe runs and complex networks, reducing oil consumption while maintaining reliable lubrication to prevent tool wear and downtime.
The L74M-4AP-EDN is designed to align with CE marking and typical industrial standards for pneumatic components. Exact certification status may vary by batch or regional requirements; consult the datasheet linked in the product downloads to confirm the current certifications applicable to your region and application.
Maintenance is simplified by the closed bowl design and the available L74M-KIT service kit for rapid field servicing, reducing downtime. The combination of stable lubrication, reduced oil waste, and longer tool life translates to lower operational costs and a favorable return on investment over the equipment lifecycle.
