Norgren L64C-NNP-EAN Oil Fog Lubricator - Olympian Plus
Part Number: L64C-NNP-EAN
Quick Summary
Norgren L64C-NNP-EAN oil fog lubricator is designed to deliver precise oil misting for compressed air systems in automation lines. Engineers often contend with uneven lubrication that accelerates wear and reduces actuation reliability; this device helps maintain stable lubrication across fluctuating demand. While certification details vary by region, CE conformity and IP-rated considerations, along with SIL safety concepts in the Olympian Plus range, are important for compliant installations. By combining modular mounting, durable materials, and predictable lubrication performance, this solution supports improved uptime and lower maintenance costs in industrial environments. Secondary keywords such as compressed air lubricator and automatic lubrication help your procurement and engineering teams assess fit.

Feature: Olympian Plus Plug-In yoke system delivers modularity and rapid mounting changes. Benefit: installation time is reduced and future upgrades can be deployed without dismantling the unit, lowering downtime on automation lines. Application: ideal for OEMs and integrators updating tool sets, conveyors, or robotics cells where space is tight and configurations shift frequently. Feature: Oil fog lubrication supports heavier lubrication over short distances. Benefit: delivers reliable misting for large bore cylinders, air motors, and power tools without excessive oil, reducing waste and cleanup. Application: effective at point-of-use lubrication on compact air circuits in manufacturing cells and maintenance shops. Feature: Built-in flow sensor maintains a near-constant oil/air ratio across a range of flows. Benefit: ensures consistent lubrication during startup and peak demand, extending component life and reducing wear. Application: suits lines with variable load, from automated presses to pneumatic hand tools. Feature: Closed-bowl drain with a 1 L metal bowl and nitrile elastomer seals. Benefit: reduces oil leakage, keeps workspaces clean, and simplifies maintenance cycles. Application: ideal for washdown environments and lines requiring controlled, contained lubrication. Feature: Durable zinc alloy body and aluminium bowl with nitrile seals ensure long service life in demanding environments. Benefit: high reliability and compatibility with common compressed-air systems. Application: retrofit into existing L64C setups or new OEM installations, with mounting options via Y64A yoke assemblies and wall brackets such as 74504-50.

FAQs
The L64C-NNP-EAN supports the Olympian Plus modular ecosystem with plug-in yoke configurations and compatibility across the L64C range. It accommodates a without-yoke port option and can be mounted using a wall bracket (74504-50) or integrated Y64A yoke assemblies (N1N, N2N, N3N variants). For retrofits, verify inlet pressure, drainage, and available space to ensure a seamless fit.
For reliable lubrication, operate at up to 17 bar inlet pressure and leverage the unit’s 72 dm3/s flow with a start point around 1.5 dm3/s. The oil fog type provides consistent oil deposition on large bore cylinders and air tools even as flow changes. Ensure your system can sustain adequate oil supply and avoid oversaturation in downstream lines.
The L64C-NNP-EAN is rated for -20 to 80 °C operation and uses nitrile elastomer seals, a zinc alloy body, and an aluminium bowl for rugged service. For washdown environments or aggressive chemicals, confirm ambient ratings and consider washdown-approved variants if your application requires enhanced ingress protection or chemical compatibility with the lubricating oil.
You can install in configurations without a yoke in some setups, but most installations use Y64A yoke assemblies or the Wall Bracket 74504-50 for secure mounting. The product remains compatible with the L64C family and Olympian Plus accessories. Before ordering, confirm port arrangements, space, and mounting clearance to choose the optimal mounting strategy.
Maintenance is driven by the closed-bowl design, straightforward bowl inspection, and predictable lubrication performance, contributing to longer cylinder life and reduced lubricant waste. ROI stems from lower downtime, fewer manual oilings, and extended tool life. Use the flow sensor to optimize lubrication intervals and minimize consumable costs without compromising reliability.
