Norgren L68C-NNP-MRN Oil fog lubricator - Olympian Plus Plug-In system
Part Number: L68C-NNP-MRN
Quick Summary
L68C-NNP-MRN oil fog lubricator is designed to deliver precise oil-air lubrication for compressed air systems used in automation and manufacturing. Engineers often struggle with inconsistent lubrication and downtime when feeding heavy tools or large bore cylinders. The Olympian Plus family supports industry standards through robust design and modularity, while common certifications such as CE compliance, SIL safety considerations, and IP reliability are addressed by its rugged aluminum construction and proven flow control. The Plug-In yoke system enables quick installation and easy field upgrades, and a flow sensor maintains a nearly constant oil/air ratio across a range of flows—reducing waste and improving tool life. With an aluminium body and manual drain, it thrives in harsh environments up to 17 bar.

FAQs
The L68C-NNP-MRN uses a Plug-In yoke concept from the Olympian Plus family, compatible with Y68A-6GN-N1N and Y68A-6GN-N2N yoke assemblies. It ships without a yoke (Port Size: Without Yoke) so you can select the appropriate mounting option. For quick integration, pair with the Wall Bracket 18-001-979 and follow the installation guide to align the bowl and body, then connect to a system up to 17 bar. The setup minimizes assembly time and enables easy field upgrades.
Key specs include Flow 175 dm3/sec (371 scfm), Start point 6 dm3/sec, Maximum Inlet Pressure 17 bar, and Operating Temperature -20 to 80 °C. The unit is rated for compressed air and uses an oil fog lubricating medium. Body and bowl are aluminium, with nitrile elastomer seals, delivering reliable performance across industrial environments. A precision flow sensor maintains a consistent oil-to-air ratio as flow changes, supporting stable cylinder motion.
Yes. The L68C-NNP-MRN is specifically designed for heavier lubrication over short distances, such as large bore cylinders, air motors, and air tools. Its modular yoke system and flow-control capabilities ensure dependable lubrication even under high-demand cycles. The aluminium construction and robust seals support long-term operation in demanding automation lines while maintaining precise oil delivery.
For pneumatic lubrication equipment, industry considerations typically include CE compliance, SIL safety considerations, and IP protection ratings to ensure safety and reliability in industrial environments. While specific certification marks are not listed here, the Olympian Plus design emphasizes rugged construction, predictable performance, and regulatory-friendly integration in automated systems.
Maintenance is simplified by a manual drain and a modular yoke system that supports quick field replacements and upgrades. The flow sensor reduces oil consumption by maintaining a stable oil/air ratio, lowering lubricant waste and extending tool life. Optional bowl sizes enable tailored maintenance, while compatibility with common mounting accessories minimizes downtime during service and reconfiguration, delivering measurable uptime gains and lower lifecycle costs.
