Quick Summary

Norgren L74M-4GP-EDN Excelon micro fog lubricator delivers precise lubrication for general pneumatic systems. The design supports in-line or modular installation, addressing space and retrofit challenges in tight panels. Inconsistent oil/air ratios and maintenance-heavy bowls are common pain points that hinder performance; this model maintains a nearly constant ratio across varying flows with a micro-fog spray. Along with its durability, consider CE conformity, SIL reliability, and typical IP-rated protection in the Excelon family; confirm exact certifications in the datasheet. For engineers and buyers, the combination of a robust aluminium body, closed bowl, and service-friendly L74M kit reduces maintenance time while delivering reliable lubrication and extended component life in demanding factory environments. The page also aligns with compatible Excelon accessories to simplify deployment in existing systems.

Excelon micro fog design enables in-line or modular installation, reducing footprint and simplifying retrofits for compact automation panels. This feature translates to lower installation costs and faster commissioning in general pneumatic systems where space is at a premium. The micro fog lubrication delivers a fine mist, improving lubrication efficiency, reducing oil consumption, and minimizing carryover into downstream components, which translates to lower maintenance costs and longer tool life on high‑demand lines. A closed bowl with a liquid level indicator enhances safety and spill prevention, enabling safer shop-floor maintenance and easier refill scheduling in busy production environments. The aluminium body and bowl provide rugged durability and heat resistance, supporting longer service intervals in harsh factory conditions while keeping weight manageable for handling and mounting. The L74M-KIT service kit, together with compatible Excelon accessories like the T74T-4GA-P1N shut-off valve, 4316-50 porting block, 4324-50 universal bracket, and Quikclamp variants, streamlines installation, alignment, and maintenance, reducing downtime and ensuring consistent performance across multiple machines. These features support long pipework and variable demand with a predictable oil/air ratio, aligned to industry best practices for pneumatic lubrication in automation lines. The system benefits are particularly pronounced when paired with modular components for future expansion and retrofit projects, delivering scalable reliability and cost control across the facility.

FAQs

Install the L74M-4GP-EDN using a standard G1/2 port manifold or inline module. Ensure the bowl is oriented for easy access and that the line supplies clean, dry compressed air. Use compatible Excelon accessories such as the T74T-4GA-P1N shut-off valve and the 4316-50 porting block to simplify mounting and ensure leak-free operation. Optionally mount with the 4324-50 Universal Bracket or Quikclamp variants for rapid hardware changes. Verify feed lines and mounting clearances to avoid interference with adjacent components.
Expect a micro fog lubrication profile with a flow around 73 dm3/sec (155 scfm) and a start point near 0.94 dm3/sec, suitable for general pneumatic applications. The unit operates up to 17 bar inlet pressure and uses a closed bowl design to minimize oil spillage. This combination supports a stable oil/air ratio across varying demand, improving consistency and reducing lubricant waste in long pipework scenarios.
Yes. The L74M-4GP-EDN is designed to work with Excelon modular components, including the L74M service kit, T74T-4GA-P1N shut-off valve, 4316-50 Porting Block, 4324-50 Universal Bracket, and Quikclamp variants (4314-51, 4314-52) plus Quikmount pipe adapters (4315-11). This compatibility supports streamlined retrofits, straightforward expansion, and consistent performance across multiple lubricators in a shared pneumatic network.
The lubricator features an aluminium body and bowl with elastomer seals (Chloroprene and Nitrile rubber). It is designed for general use with compressed air, in environments typical for factory automation. Operating temperature ranges from -34 to 80 °C, and the unit is suitable for applications where a robust, maintenance-friendly closed-bowl design is advantageous. Check the datasheet for precise material certifications and compatibility with your process fluids.
Maintenance is streamlined by the included L74M service kit and the accessible closed-bowl design, which reduces spill risks during refills. The steady oil/air ratio across a broad flow range minimizes lubricant waste and extends component life, delivering measurable ROI through reduced downtime and longer service intervals.
