Norgren L73M-3GP-EDN Excelon micro fog lubricator - G3/8
Part Number: L73M-3GP-EDN
Quick Summary
L73M-3GP-EDN is a micro fog lubricator for inline pneumatic systems in general manufacturing for precision handling and high reliability. Engineers often face inconsistent oil/air ratios, drifting lubrication performance, and maintenance-heavy bowls prone to leakage in demanding environments. In Excelon specifications, CE conformity is common and enclosure protection is robust, while SIL-rated options are available on select variants to support safety-critical automation environments. This inline lubrication solution enables modular installation and long pipe runs, improving uptime, reducing waste, lowering maintenance costs, and supporting predictive maintenance programs for OEMs and end users across manufacturing lines. This combination of precision control and installation flexibility translates to quicker ROI for modern factories.

Feature: Inline or modular installation design enables flexible deployment across new builds or retrofits. The Excelon L73M-3GP-EDN features a compact aluminium body and a mounting pattern compatible with standard pneumatic blocks, allowing easy integration into existing layouts. Application: ideal for general manufacturing lines where space is tight and future expansions are expected, providing a fast path to added lubrication capability. This reduces the risk of misalignment during maintenance and simplifies future upgrades. Feature: Micro fog lubrication delivers a fine mist for general purpose pneumatic applications, including long or complex pipework. Business Impact: improves lubrication consistency, reduces lubricant waste, and minimizes contamination risk in sensitive processes. Application: well suited for inline lubrication on automation equipment, pick-and-place systems, and packaging lines where precise oil delivery is critical. It also helps prevent oil carryover into exhaust, keeping the workspace clean. Feature: A built-in flow sensor maintains a nearly constant oil/air ratio across wide flows. Business Impact: predictable performance supports tighter process control and easier automation programming. Application: supports variable demand on multi-branch lines or systems with fluctuating load while keeping oil usage stable. This makes line changeovers smoother and reduces operator intervention. Feature: Durable aluminium body and bowl with elastomer seals for reliable operation in demanding environments. Business Impact: longer service life, reduced replacement costs, and lower maintenance intervals. Application: suitable for harsh factory floors and locations with vibration or temperature variation within -34 to 80 °C. Aluminium construction also aids heat dissipation and corrosion resistance. Feature: Closed-bowl drain design and G3/8 port size with inline fitting compatibility. Business Impact: minimizes drips during servicing and simplifies retrofits on existing equipment. Application: drop-in replacement on standard 3/8 inch pneumatic circuits and automation lines. The design aligns with common industry components, easing procurement and stocking for maintenance teams. This combination supports Industry 4.0 integrations through stable lubrication data and predictable maintenance schedules.

FAQs
The L73M-3GP-EDN is designed for inline or modular installation with standard G3/8 fittings. Start by mounting the unit on a stable bracket or near the air supply, connect the inlet and outlet lines, and verify the closed-bowl drain is sealed. Use Norgren installation guides to ensure proper alignment and leak-free operation.
Expect a fine mist that maintains consistent lubrication across extended runs. With a flow of 38 dm3/sec and a start point of 0.71 dm3/sec at up to 17 bar, the unit delivers stable oil delivery with reduced waste, even as pipe length and load vary.
Yes, the Excelon micro fog lubricator supports general automation tasks on automotive assembly and packaging lines. Key considerations are the G3/8 port size, aluminium body, and closed-bowl drain that minimize leaks and maintenance while delivering reliable lubrication to multiple actuators on busy lines.
Check the exact SKU datasheet for CE conformity and enclosure protection ratings. Excelon family commonly aligns with CE requirements, and select variants offer SIL-rated configurations for safety-critical applications. Always confirm the model-specific documentation and installation guides before procurement.
The L73M-3GP-EDN reduces lubricant waste via precise micro fog delivery, minimizes downtime with reliable inline installation, and lowers maintenance costs through a durable aluminium design and clean closed-bowl drain. Together, these factors shorten time-to-value and improve uptime across manufacturing lines.
