Norgren L74M-6GP-EDN Excelon Micro Fog Lubricator - G3/4
Part Number: L74M-6GP-EDN
Quick Summary
Excelon micro fog lubricator L74M-6GP-EDN delivers precise oil mist for general pneumatic systems. Long, complex pipework often leads to uneven lubrication and higher maintenance costs. In practice, regulatory considerations like CE marking, IP-rated enclosures, and SIL assessments should be reviewed to align with your safety and reliability requirements. Designed for inline or modular installation, the Excelon L74M combines a compact form with a durable aluminium body to reduce part counts while improving lubrication consistency and system uptime.

Excelon Plus micro fog lubricator, G3/4, Metal bowl closed
Feature → Business Impact → Application: The Excelon micro fog technology delivers ultra-fine oil mist, increasing lubrication efficiency and reducing oil carryover, which lowers consumable costs and minimizes residue in sensitive equipment. This translates to longer component life and lower maintenance intervals across general pneumatic circuits, especially where long pipe runs or dense manifolds are involved. Application: general purpose pneumatic applications and inline installations benefit from the nearly constant oil/air ratio provided by the integrated flow sensor, improving process stability and repeatability.Feature → Business Impact → Application: The closed metal bowl with a liquid level indicator reduces maintenance risk by providing clear visibility and duty-cycle predictability, enabling proactive service planning. Application: inline or modular configurations in production lines and machining centers where quick servicing without system downtime is essential.Feature → Business Impact → Application: G3/4 port size and 17 bar maximum inlet pressure offer broad compatibility with common pneumatic circuits and tools, simplifying procurement and integration. Application: installations leveraging 4316-50 Porting Block or T74T-6GA-P1N modular components for fast, reliable assembly in automation lines.Feature → Business Impact → Application: Aluminium body and aluminium bowl deliver durability and corrosion resistance in harsh industrial environments, reducing replacement costs and enabling longer service life. Application: metal-bodied Excelon lubricators in factory floors, packaging lines, and material handling systems where resilience is key.Feature → Business Impact → Application: The flow specification of 73 dm3/sec (155 scfm) with a defined start point (0.94 dm3/sec) supports predictable lubrication across varying loads, aiding energy efficiency and high-accuracy dosing. Application: high-demand pneumatic cycles and long pipework where consistent lubrication is critical for tool wear and finish quality.Feature → Business Impact → Application: Availability of a service kit (L74M-KIT) and compatible mounting accessories (Quikmount, Universal Bracket, Quikclamp) reduces downtime and speeds maintenance, improving total cost of ownership. Application: retrofits and new installs across existing lines, with straightforward upgrades using the Excelon ecosystem.

FAQs
To install inline, ensure the supply line is depressurized, mount the L74M in the desired location, and connect the G3/4 ports to the compressed air line using compatible fittings. For quick mounting and alignment, consider using the 4316-50 Porting Block and T74T-6GA-P1N modular valve in conjunction with the Excelon accessories. After installation, bleed any trapped air and verify oil mist output with the included lubrication sensor guidelines.
Expect a flow of 73 dm3/sec (155 scfm) with a defined start point at 0.94 dm3/sec and a maximum inlet pressure of 17 bar. The micro fog technology provides a near-constant oil/air ratio across varying flows, improving lubrication consistency on long pipe runs and complex manifolds while reducing oil carryover and mess.
Yes. The micro fog design delivers ultra-fine mist designed for long piping networks, maintaining lubrication uniformity where oil delivery can otherwise degrade over distance. It integrates with inline or modular Excelon configurations, enabling scalable lubrication in expanding automated lines.
Maintenance is simplified with the L74M-KIT service kit and compatible accessories like Quikmount and Universal Bracket. Regular checks on bowl level visibility, elastomer seal condition, and airflow consistency are recommended. Follow the Installation Guide PDF for step-by-step servicing, replacement parts, and torque specs to minimize downtime.
Verify CE marking, IP ratings for enclosure and regional SIL considerations based on your safety strategy. Regulatory requirements vary by region and application, so consult the datasheet and local standards to ensure full compliance for your pneumatic lubrication system.
