Norgren L68M-8AP-ERN Lubricator - Olympian Plus Micro fog
Part Number: L68M-8AP-ERN
Quick Summary
The Norgren L68M-8AP-ERN is a micro fog lubricator for general pneumatic systems requiring precise oil-to-air ratios. Engineers often face inconsistent lubrication along long or intricate pipework, which increases wear, downtime, and maintenance costs. The data here does not list CE, SIL, or IP certifications; verify with your supplier to ensure regulatory compliance for your environment. Built on the Olympian Plus platform with a plug-in yoke system, it enables modular installation while delivering reliable, low-maintenance lubrication for automated lines. Flow sensing helps maintain a near-constant oil/air ratio over varying flows, and the design includes a 1" PTF port with a closed aluminium bowl, supporting compact, robust integration.

Feature → Micro fog lubrication delivers an extremely fine oil mist, improving coverage and reducing lubricant consumption. Business Impact → Lower operating costs, reduced waste, and extended actuator life across pneumatic networks. Application → Ideal for general pneumatic systems and long, complex pipework where precise lubrication improves performance. By contrast, traditional fat-lubrication methods may lead to inconsistent oil delivery and higher maintenance overhead. Feature → Flow sensor maintains a nearly constant oil/air ratio over a range of flows. Business Impact → Predictable performance and easier process control, enabling tighter automation tolerances. Application → Beneficial in systems with fluctuating demand or multi-branch networks where flow varies. Feature → Olympian Plus plug-in yoke system offers modularity and quick field installation. Business Impact → Faster commissioning, simplified upgrades, and scalable control across multi-plant environments. Application → Compatible with optional mounts and service kits, enabling rapid modernization of existing lines. Feature → 1" PTF port and closed aluminium bowl protect against contaminants while maintaining a compact footprint. Business Impact → Reduced maintenance downtime and improved reliability in harsh shop-floor environments. Application → Suitable for space-constrained assemblies on automated lines where bowl integrity is critical. Feature → Aluminium body and bowl with nitrile elastomers provide durable construction for industrial use. Business Impact → Long service life under typical shop air conditions and resistance to oil-based lubricants. Application → Fits standard pneumatic power units and general purpose lubrication schemes. Feature → Optional service kit and readily available mounting accessories support ongoing maintenance and upgrade programs. Business Impact → Lower total cost of ownership through spare-part readiness and easier retrofits. Application → Useful for continuous improvement projects in manufacturing automation.

FAQs
The L68M-8AP-ERN supports the Olympian Plus plug-in system and compatible yoke assemblies (Y68A-8AN-N1N, N2N). For mounting, use the Wall Bracket 18-001-979, and consider the T68H-8AB-B2N shut-off valve as an integrated accessory. Quick-fill nipple 18-011-021 is available for maintenance compatibility. This setup enables fast, modular installation in existing lines.
Key parameters include a 1" PTF port, closed aluminium bowl, operating temperature from -20 to 80 °C, maximum inlet pressure of 17 bar, and a flow rating of 175 dm3/sec (371 scfm). The unit uses aluminium bodies and nitrile elastomers, with overall dimensions of 264 mm in height, 190 mm in length, and 108 mm in width, weighing 2.04 kg.
Yes. The micro fog design, combined with a flow sensor and modular Olympian Plus plug-in system, is specifically aimed at long or complex pipework. It maintains a near-constant oil/air ratio across varying flows, improving lubrication consistency and system reliability in challenging pneumatic networks.
Certification details such as CE, SIL, or IP ratings are not listed in the provided data. To ensure regulatory compliance for your application, verify with the supplier or Norgren directly and request the latest certification documentation for your region and industry.
Maintenance benefits come from the closed-bowl design, modular plug-in system, and availability of a service kit (L68M-KIT). The flow sensor enables stable lubrication, reducing oil waste and wear, which translates to longer tool life and reduced downtime—driving a favorable return on investment in automation-heavy environments.
