The micro fog lubrication technology delivers a fine, consistent mist that minimizes oil consumption while maintaining a stable oil/air ratio across varying flows. This translates to lower operating costs, reduced maintenance intervals, and improved machine health in high-throughput automation lines. It excels in general automation projects where long pipe runs and changing demands require steady lubrication. The Olympian Plus Plug-In yoke system offers perfect modularity, enabling quick mounting changes and future expansion; even when installed without a fixed yoke, the design supports straightforward integration with available Y68A accessories for retrofits and upgrades, reducing downtime. Flow is rated at 175 dm3/sec (371 scfm) with a start point at 6 dm3/sec, and a flow sensor maintains nearly constant oil/air ratio, ensuring predictable performance across duty cycles. Operation remains robust across the stated temperature range and pressure conditions, delivering reliable lubrication where it matters most. The aluminium body and bowl provide corrosion resistance and durability in demanding environments, while nitrile elastomers manage seals and gaskets effectively. With a closed-bowl drain and a 1 L capacity, servicing is straightforward and spill risk is minimized, supporting cleanroom and general manufacturing standards. Optional bowls and mounting accessories simplify installation on existing lines and facilitate scalable lubrication across multiple machines. Service kit L68M-KIT keeps wear parts and seals up-to-date, extending service intervals and protecting equipment lifetime.

FAQs
The L68M-NNP-EUN is designed for modular installation. When used with a yoke, employ the Olympian Plus Plug-In system and compatible Y68A assemblies (N2N or N1N variants) for quick mounting and future expansion. For a no-yoke setup, mount using standard brackets and ensure space for the 320 mm height and 180 mm length; refer to the L68M installation guide for exact steps and torque specs.
Key performance figures include a maximum flow of 175 dm3/sec (371 scfm) with a start point at 6 dm3/sec. The integrated flow sensor works to keep a nearly constant oil/air ratio across the operating range, delivering stable lubrication in variable process conditions and long piping runs typical of general automation applications.
Yes. The Olympian Plus design and micro fog technology are optimized for long runs and complex piping networks. The aluminium body and closed-bowl design minimize oil splash and leakage, while the modular mounting options and available service accessories support scalable lubrication across multiple machines in a factory setting.
Certification details such as CE marking, IP rating, and SIL considerations vary by model and region. Please consult the official datasheet and local compliance documentation for the exact status of L68M-NNP-EUN. This ensures alignment with electrical safety, enclosure protection, and safety integrity requirements for your specific application.
Maintenance is simplified by the 1 L closed-bowl design and accessible components. Use the service kit L68M-KIT to replace wear parts and seals and maintain peak performance. Regular service reduces downtime, extends component life, and lowers total cost of ownership in ongoing automation deployments.
