Norgren L74C-3GP-QDN Excelon oil fog lubricator - G3/8
Part Number: L74C-3GP-QDN
Quick Summary
Oil fog lubricator for compressed air systems delivers precise lubrication for pneumatic tools, large-bore cylinders, and air motors in automated lines. Inconsistent lubrication and frequent maintenance downtime challenge uptime and tool life, increasing cycle times and overall operating costs. This Excelon family commonly carries CE conformity and robust enclosure options suitable for IP-rated environments, depending on installation specifics. The design supports inline or modular installation, enabling flexible layouts and simplified retrofits with G3/8 ports and manual drain. By maintaining a nearly constant oil-to-air ratio across varying flows, operators gain predictable lubrication, reduced waste, and easier maintenance planning. This ensures reliable performance in demanding ISO-rated environments.

Inline or modular installation is built into the Excelon design, letting you deploy L74C-3GP-QDN in fresh lines or retrofit existing ducts with minimal disruption. This translates to faster commissioning, reduced installation costs, and straightforward scalability for future automation needs. The G3/8 ports and compact form factor support clean routing and simple integration with Excelon accessories for a streamlined retrofit and future expansion. Heavy lubrication at short travel distances is supported by the oil fog approach, ideal for large bore cylinders, air motors, and air tools. Operators benefit from improved wear protection, reduced tool chatter, and longer cycle life when high lubrication density is required over short runs. A flow sensor maintains a nearly constant oil-to-air ratio across a broad range of flows, delivering consistent performance, lower variability, and reduced oil waste. This helps you meet process variability without over-lubricating and lowers maintenance intervals, enabling predictable factory uptime. Robust aluminium body and bowl, plus a manual drain and G3/8 port, provide durable operation in hot, dusty, or workshop environments. The modular Excelon platform supports compatible accessories like shut-off valves, porting blocks, and universal brackets for streamlined integration and future expansion. Service kits such as L74M and compatible accessories (e.g., 4316-50 porting block, 4324-50 universal bracket, T74T-3GA-P1N shut-off valve) simplify maintenance and enable quick upgrades. For OEMs and end users, this reduces downtime, lowers lifecycle costs, and protects automation investments through reliable, traceable lubrication control.

FAQs
To install the L74C-3GP-QDN, select inline or modular mounting per the Excelon design, then connect at G3/8 ports with a manual drain for easy maintenance. Ensure clean, dry compressed air and appropriate line sizing to avoid pressure drop. The unit is designed for straightforward retrofit and compatibility with Excelon accessories such as shut-off valves and mounting brackets.
The lubricator delivers up to 91 dm3/sec (193 scfm) with a stable oil-to-air ratio and a start point around 0.94 dm3/sec, across a maximum inlet of 17 bar. This yields consistent lubrication across low to high demand, minimizes oscillations in oil delivery, and reduces lubricant waste while protecting auxiliary equipment in the line.
Yes. The oil fog approach provides higher lubrication density over short runs, ideal for large bore cylinders, air motors, and high-load air tools. This results in improved wear protection, reduced tool wear, and longer service life, while preserving compact packaging within the Excelon modular framework.
Certification details vary by configuration, but Excelon products commonly feature CE conformity and robust enclosure options suitable for IP-rated environments. Always verify the exact model datasheet and installation guide for current certification status and regional regulatory requirements before deployment to ensure compliance and safe operation.
Integrating the L74C-3GP-QDN with service kits like L74M and compatible accessories (porting blocks, brackets, shut-off valves) reduces downtime, simplifies maintenance, and extends the life of connected equipment. This modular approach lowers lifecycle costs, improves uptime, and protects automation investments by delivering reliable, traceable lubrication control across your system.
