Feature: Micro fog lubrication with a precision flow sensor → Business Impact: Maintains a near-constant oil/air ratio across varying flows, improving component life and reducing lubricant waste → Application: General-purpose pneumatic lines with long pipework or complex routing. Feature: Olympian Plus plug-in yoke system → Business Impact: Modular, rapid field upgrades reduce downtime and service time during installation or expansion → Application: OEM lines and retrofit projects where quick assembly and interchangeability matter. Feature: Closed aluminium bowl and aluminium body → Business Impact: Durable, corrosion-resistant housing that minimizes oil splashes and simplifies containment during changes → Application: Harsh factory environments and high-use machining cells. Feature: Materials and elastomers (Aluminium body and bowl, nitrile elastomer seals) → Business Impact: Robust temperature tolerance and chemical resistance that extend service life and maintain performance → Application: Broad temperature ranges (-20 to 80 °C) and standard lubricants. Feature: Operating range and pressure (−20 to 80 °C, up to 17 bar, G3/4 port) → Business Impact: Flexible deployment across diverse equipment fleets and international standards → Application: General purpose automation lines with standard pneumatic ports. Feature: Flow range and start point (6 to 175 dm3/sec; 371 scfm; start at 6 dm3/sec) → Business Impact: Scalable lubrication suitable for both small actuators and high-flow cylinders, reducing oversupply or under-lubrication → Application: Systems with variable loads and long pipe runs. Feature: Compatibility with accessories (L68M-KIT, T68H valves, T40B silencers) → Business Impact: Integrated maintenance kits and modular control options streamline service planning and stock management → Application: Retrofit and upgrade projects across a mixed fleet. Industry context note: In modern automation environments, long-term reliability hinges on dependable lubrication and modular, serviceable components. The L68M-6GP-ERN aligns with this demand by combining precision micro fog delivery, plug-in modularity, and durable construction to support predictable performance, compliant installation practices, and simplified maintenance schedules.

FAQs
This lubricator is designed for G3/4 ports and suits standard general-purpose pneumatic circuits. To install, mount using the Olympian Plus plug-in yoke, connect the G3/4 inlet, and secure the closed-bowl assembly. Verify space for the aluminium body and ensure the downstream piping avoids sharp bends to maintain steady spray.
The integrated flow sensor helps maintain a near-constant oil/air ratio across varied flows, reducing lubricant waste and improving cylinder responsiveness. Start flow is around 6 dm3/sec with a maximum around 175 dm3/sec, making it suitable for both small actuators and higher-demand lines in general automation.
Yes. With a flow range up to 175 dm3/sec (371 scfm) and a robust aluminium body, the unit maintains reliable lubrication over extended runs. The micro fog approach minimizes oil carryover and condensation issues, while the closed bowl reduces spill risk in longer installations.
Please verify the configurations against your project requirements, especially any CE, IP, or SIL-related standards for your machinery and plant. The catalog does not specify certifications for this model, so confirm with procurement or the supplier for your specific regulatory needs.
Expect lower maintenance intervals due to improved lubrication consistency, reduced lubricant waste from precise oil/air ratios, and easier serviceability via the plug-in system. In lines with variable flow or long pipework, the system can reduce downtime and extend actuator life, contributing to a favorable total cost of ownership.
