Excelon Plus micro fog lubricator, G3/4, Guarded plastic bowl closed
The Excelon L74M-6GP-QPN uses micro fog lubrication combined with an integrated flow sensor to maintain a nearly constant oil/air ratio as flow varies. This directly reduces oil waste and improves lubrication precision, which translates into longer component life and lower operating costs for general pneumatic systems. The design supports in-line or modular installation, enabling easy retrofits and scalable lubrication across evolving production lines, while minimizing downtime during upgrades or expansions. With a manual drain and guarded polycarbonate bowl, maintenance teams gain simpler periodic checks and safer operation in busy environments. Aluminum body construction delivers robust durability with lighter weight, and the durable materials couple with a sealed interface to resist contaminants in harsh factory air. Compatibility with Excelon modular valves and service kits simplifies procurement, installation, and ongoing servicing, helping teams meet lean manufacturing targets and budget predictability.

FAQs
The L74M-6GP-QPN is designed for both inline and modular installation within Norgren's Excelon system. For inline use, mount the unit directly in the air line using the G3/4 port, ensuring the flow direction matches the unit markings. For modular setups, pair the lubricator with compatible Excelon blocks and shut-off valves (e.g., T74T-6GA-P1N) to create a scalable lubrication station. Always verify clearance around the guard, and use the Quikclamp mounting accessories where applicable to reduce installation time and vibration.
Key specs include a G3/4 port size, maximum inlet pressure of 10 bar, and a flow range starting at 0.94 dm3/sec with a total flow of 73 dm3/sec (155 scfm). The lubricator delivers micro fog lubrication with a aluminium body and polycarbonate bowl, and it uses a manual drain. Operating temperature ranges from -34 to 50 °C, ensuring functionality across diverse industrial environments.
Yes. The Excelon micro fog design and the integrated flow sensor are specifically aimed at maintaining a stable oil/air ratio over long runs and intricate layouts. The device's compact footprint and inline/modular installation capability reduce pressure drop concerns and help ensure consistent lubrication even as pipe lengths increase or configurations change.
The L74M-6GP-QPN is associated with the Excelon family that emphasizes robust industrial design. While specific certificates can vary by region, the product is positioned for CE-compliant use in Europe and is designed to meet industrial safety and reliability expectations common to IP-rated enclosures and SIL-ready configurations within the Excelon line. Always confirm current certification status for your exact lot with the distributor or manufacturer.
Maintenance is streamlined by a guard-protected polycarbonate bowl and a manual drain, minimizing accidental spills and simplifying routine checks. The L74M service kit (L74M-KIT) and compatible Silencers and valves (e.g., T40B1800, 4314-51/4314-52) support quick part replacement and system cleanliness. Regular inspections of the bowl seal, flow sensor, and connection fittings help sustain the near-constant oil/air ratio, reducing overall lubrication costs and downtime.
