Norgren L74C-4GP-QDN Excelon Oil Fog Lubricator - G1/2
Part Number: L74C-4GP-QDN
Quick Summary
L74C-4GP-QDN oil fog lubricator from Norgren provides precise, inline lubrication for pneumatic systems in manufacturing and automation. Engineers often struggle with inconsistent lubrication that leads to cylinder wear, tool downtime, and unpredictable performance. Designed for CE-compliant European deployment and robust in dusty environments, this Excelon component supports IP-rated protection and safe integration with safety-critical lines. With inline installation flexibility and measurable lubrication control, it helps reduce maintenance costs while improving cycle times. In practice, the combination of a metal bowl, flow sensor, and manual drain simplifies scheduled servicing and uptime.

FAQs
The L74C-4GP-QDN supports both inline and modular Excelon installations, allowing easy integration into existing lines or expansion with minimal rework. It is compatible with the Excelon ecosystem, including the T74T-4GA-P1N modular shut-off valve and the 4316-50 porting block for streamlined piping and future upgrades.
Key performance specs include oil fog lubrication with a flow of 91 dm3/sec (193 scfm), start point at 0.94 dm3/sec, maximum inlet pressure of 17 bar, and a G1/2 port size. The device uses an aluminium body and bowl with a manual drain to support reliable, repeatable lubrication in demanding applications.
Yes. The Excelon L74C-4GP-QDN is designed for heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and high-use air tools. The flow characteristics and robust construction support consistent performance in these high-demand applications.
The Excelon L74C-4GP-QDN is designed for industrial use and supports common European and international requirements (CE-related expectations) for safety and reliability. In practice, users should verify local electrical and pneumatic compliance for their specific installation and environment, particularly where SIL, IP, or other safety standards apply to surrounding equipment.
Maintenance is aided by a manual drain and the durable aluminium body and bowl, reducing corrosion concerns and simplifying servicing. The integrated flow sensor ensures consistent lubrication, reducing oil waste and improving tool life. For ROI, expect lower downtime, longer cylinder life, and predictable maintenance planning, especially in high-cycle industrial lines.
