Norgren L68C-NNP-MUN Oil Fog Lubricator - Olympian Plus
Part Number: L68C-NNP-MUN
Quick Summary
L68C-NNP-MUN oil fog lubricator delivers precise oil mist for compressed air systems in short-distance lubrication. Operators often face uneven lubrication, causing cylinder wear, tool chatter, and unplanned downtime. Although the data does not list explicit certifications, industrial pneumatic components typically meet CE safety directives and ISO quality standards, while the Olympian Plus family emphasizes durable aluminium construction and a plug-in yoke system for scalable, field-serviceable installations. This combination supports faster commissioning, lower lubricant waste, and easier maintenance, especially when paired with Norgren's Y68A yoke assemblies and the L68C service kit. The integrated flow sensor further enhances repeatability, making it a pragmatic choice for manufacturing environments pursuing reliability and efficiency.

The Olympian Plus plug-in yoke system offers true modularity, allowing quick field upgrades and easy expansion as line requirements evolve. This reduces downtime during changeovers and simplifies stocking of spare parts by standardizing mounting interfaces. In applications requiring swift reconfiguration—such as multi-circuit lines—the modular approach pays for itself through faster turnaround. Oil fog lubrication is ideal for heavier lubrication near large bore cylinders, air motors, and power tools. The oil mist delivery minimizes lubricant consumption while delivering reliable film strength, improving cylinder life and tool performance. This translates into longer interval maintenance and lower consumable costs on automated lines. A built-in flow sensor ensures a nearly constant oil/air ratio across a range of flows, delivering consistent lubrication at start points as low as 6 dm3/sec and up to full capacity. This improves process stability, reduces lubricant waste, and helps meet repeatable cycle times in production. The 1 l metal bowl with manual drain provides straightforward maintenance and an easy way to remove used oil without powering down equipment, with optional bowl sizes available to fit different line requirements. The aluminium body and bowl, coupled with nitrile rubber elastomers, deliver robust corrosion resistance across a wide operating window (-20 to 80 °C) and a maximum inlet pressure of 17 bar, enabling reliable operation in varied factory environments. The Without Yoke port keeps mounting options flexible, while compatible accessories such as Yoke assemblies Y68A-6GN-N1N/N2N, a Wall Bracket 18-001-979, and the L68C service kit support fast installation and easy ongoing maintenance.

FAQs
Begin by selecting compatible mounting hardware: use Yoke assemblies Y68A-6GN-N1N or N2N for modular mounting, and the Wall Bracket 18-001-979 for wall installation. The port size is Without Yoke, so install the lubricator onto the appropriate support and connect supply lines within the 17 bar maximum. Finish with the L68C-KIT service kit if planned maintenance is required. Typical startup involves verifying flow settings, ensuring the manual drain is accessible, and confirming the aluminium bowl is securely seated. This approach minimizes downtime during integration and facilitates quick future upgrades.
Expect precise oil fog lubrication capable of handling 175 dm3/sec (371 scfm) with a start point at 6 dm3/sec and a maximum inlet pressure of 17 bar. The integrated flow sensor maintains a near-constant oil-to-air ratio across a broad flow range, improving repeatability and reducing waste. Suitable for heavy lubrication over short distances to support large bore cylinders, air motors, and air tools, it also benefits from a robust aluminium construction for durability in manufacturing environments.
The L68C-NNP-MUN operates from -20 to 80 °C, which covers most standard factory conditions. Its aluminium body and nitrile elastomer seals provide good corrosion resistance and chemical compatibility for typical pneumatic use. For outdoor or harsh environments, verify enclosure protection and potential exposure to elements, and ensure installation location adheres to the recommended operating conditions.
Maintenance is straightforward thanks to a manual drain and a replaceable 1 L aluminium bowl. Use the L68C service kit for routine inspections, seals, and parts refresh. Periodic checks should confirm the flow sensor remains accurate, the bowl seal is intact, and mounting hardware stays tight. Optional bowl sizes support changing line requirements, while the modular yoke system keeps spare parts simple to stock.
Modularity reduces downtime during line changes and expands capacity without reengineering the system, while the flow sensor lowers lubricant waste and extends component life, driving tangible savings. Compatibility with accessories such as Y68A yoke assemblies, wall brackets, and the service kit streamlines installation and ongoing maintenance, delivering faster time-to-value for automation projects and improving overall equipment effectiveness.
