Feature → Business Impact → Application: Inline or modular installation enables flexible plant layouts and easier retrofits, reducing project time and wiring complexity while maintaining a nearly constant oil/air ratio across a wide flow range; this improves overall pneumatic efficiency in automated lines and speed of changeovers for varying tool requirements. Feature → Durable materials (aluminium body, polycarbonate bowl) yields improved vibration resistance and longer service life, lowering replacement costs and downtime in harsh factory environments; ideal for high-use facilities that operate large bore cylinders, air motors, and air-powered tools. Feature → Manual drain simplifies maintenance and reduces leak paths; the predictable drainage routine supports cleaner lubrication management and lowers unscheduled maintenance. Feature → Flow specification (91 dm3/sec, 193 scfm) and start point (0.94 dm3/sec) provide clear guidance for system designers to achieve target lubrication at given pressures; this minimizes over-lubrication and lubricant consumption. Feature → G3/8 port size and 10 bar max inlet pressure offer compatibility with standard pneumatic feeds and quick integration into existing manifolds, improving installation speed and reducing downtime. Feature → Guarded plastic bowl option and Excelon family compatibility with mounting accessories (4324-50 Universal Bracket, 4314-51 Quikclamp, 4314-52 Quikclamp with wall bracket) support safer operation and adaptable mounting in confined spaces. Industry context: In manufacturing environments requiring reliable lubrication for large actuators and hand tools, this lubricator helps maintain performance while reducing total cost of ownership through predictable maintenance intervals and compatibility with common automation components.

FAQs
The L74C-3GP-QPN uses a G3/8 port and is designed for inline or modular installation. It is compatible with common mounting accessories such as the 4324-50 Universal Bracket and the 4314-51 Quikclamp, with options for wall mounting via 4314-52. A manual drain enables straightforward servicing without disassembling the system.
Key specs include flow of 91 dm3/sec (193 scfm) and a start point of 0.94 dm3/sec, with a maximum inlet pressure of 10 bar and operation on compressed air. This combination supports reliable oil fog delivery across typical industrial loading conditions while helping maintain a consistent oil-air ratio.
Yes. The Excelon line is intended for heavier lubrication needs over shorter distances, which is common with large bore cylinders, air motors, and heavy-duty air tools. The aluminium body and polycarbonate bowl provide durability in demanding environments, while the oil fog lubrication approach supports higher lubrication requirements.
The provided data does not list explicit CE, SIL, or IP ratings for the L74C-3GP-QPN. For compliance information, refer to the datasheet (Datasheet PDF) or contact Norgren directly to confirm current certifications and regional approvals before deployment in regulated applications.
Maintenance benefits include a manual drain for controlled lubricant removal and a guarded bowl design to reduce contamination ingress. The Flow sensor maintains a stable oil/air ratio over varying flows, reducing waste and downtime. Material choices (aluminium body, polycarbonate bowl) support longevity in industrial settings and predictable lifecycle costs.
