Norgren L74C-6GP-QPN Oil Fog Lubricator - G3/4 Port
Part Number: L74C-6GP-QPN
Quick Summary
The L74C-6GP-QPN oil fog lubricator by Norgren is designed to deliver precise oil-air lubrication for pneumatic lines in automation and manufacturing environments. Engineers often struggle with inconsistent lubrication that leads to accelerated wear, variable tool performance, and unplanned downtime. While the Excelon line aligns with common industry standards such as CE compliance and region-specific safety ratings, always verify the exact SIL, CE, and IP ratings on the specified variant. This solution supports inline or modular installation and complements existing Excelon components, offering reliable lubrication with minimal workflow disruption and improved overall equipment efficiency.

Excelon Plus oil fog lubricator, G3/4, Guarded plastic bowl closed
Excelon oil fog design provides a controlled oil-air mixture that translates to longer component life and reduced maintenance downtime in high-cycle applications. Business impact: smoother operation, lower tool wear, and predictable cycle times in large bore cylinders and air tools. Application: ideal for automation cells and heavy-duty pneumatic lines where heavier lubrication is required over short distances. The G3/4 port size and guarded plastic bowl with manual drain simplify installation and maintenance, reducing retrofit time and operator intervention. Business impact: faster commissioning and safer operation, with fewer spillages. Application: new lines and modular installations in OEM and end-user facilities. The aluminium body with a polycarbonate bowl offers robust durability with light weight, improving handling during maintenance rounds. Business impact: lower total cost of ownership and safer asset handling. Application: high-use environments with frequent servicing. The unit supports a flow of 91 dm3/sec (193 scfm) and a start point of 0.94 dm3/sec, ensuring a nearly constant oil/air ratio across a wide operating range. Business impact: consistent lubrication, improved cylinder response, and better tool life. Application: large-scale pneumatic systems and high-flow circuits. Optional fittings include T74T-6GA-P1N Excelon 3/2 modular shut-off valve, and mounting options 4314-51 Quikclamp or 4314-52 wall-mount bracket, enabling quick, scalable installations. Business impact: streamlined integration with existing Excelon components and simplified upgrading of control sequences. Application: retrofits and new builds. Silencers like T40B1800 help minimize downstream noise, supporting compliant and quieter plant operation. Application: noise-sensitive environments and ISO silenced systems. The manual drain provides straightforward maintenance control, reducing inadvertent loss of lubrication while enabling precise service intervals. Business impact: lower lubricant waste and predictable maintenance windows. Application: daily operations and long-term asset reliability.

FAQs
The lubricator supports inline installation and modular setups. Mounting accessories include Quikclamp options 4314-51 and 4314-52 (wall mounting), enabling fast, secure integration with existing Excelon systems and reducing installation time in new builds.
The unit uses an oil fog delivery design and flow characteristics that sustain a nearly constant oil/air ratio across a wide range of flows. With a flow of 91 dm3/sec and a start point of 0.94 dm3/sec, it delivers reliable lubrication for high-demand lines such as large bore cylinders and air tools.
Yes. The Excelon oil fog approach provides heavier lubrication over short distances, making it well-suited for large bore cylinders, air motors, and air tools that require robust lubrication without over-saturation.
Certifications vary by region and variant. Common industrial standards for this product family include CE marking; verify the exact SIL, CE, and IP ratings on the specific L74C-6GP-QPN variant datasheet and installation guide before deployment.
The unit uses a manual drain, allowing controlled maintenance intervals and reducing lubricant waste. Combined with its durable aluminium body and guard, maintenance is straightforward, downtime is minimized, and the expected asset life and process reliability improve, delivering a favorable total cost of ownership.
