Feature: Micro fog lubrication with an integrated flow sensor. Business Impact: Maintains a nearly constant oil/air ratio across a wide flow range, reducing lubricant waste and consumable costs. Application: General pneumatic systems and long pipework where steady lubrication is critical. Feature: Olympian Plus plug‑in yoke system (without yoke option). Business Impact: Modular configuration and quick field upgrades minimize downtime during changes or expansion. Application: Flexible line installation in evolving manufacturing cells. Feature: Manual drain with aluminium body and bowl. Business Impact: Simplified maintenance and robust, durable construction for harsh industrial environments. Application: Heavy-use shops and high-cycle automation lines. Feature: Wide operating temperature and pressure range (-20 to 80 °C; up to 17 bar). Business Impact: Broad suitability across varying plant climates and compressed-air systems, enabling a single lubricant for multiple lines. Application: Plants with mixed process temperatures and pressures. Feature: Flow specification (start point 6 dm3/sec; max 175 dm3/sec). Business Impact: Efficiently supports both low-flow and high-flow regions without reconfiguration. Application: General purpose automation and longer pipe runs. Feature: Aluminium body and bowl with nitrile elastomer seals. Business Impact: Lightweight, durable construction reducing maintenance and replacement costs. Application: Industrial environments with frequent handling and exposure to oil aerosols. Feature: Compatibility with Y68A yoke assemblies and wall mounting option 18-001-979; Service kit L68M-KIT. Business Impact: Easy installation, upgrade paths, and readily available service parts. Application: OEM integrations and retrofit projects in control cabinets and machines.

FAQs
The L68M-NNP-MRN is designed to work with Norgren yoke options Y68A-6GN-N2N and Y68A-6GN-N1N, supporting quick plug-in modularity. Mounting can be facilitated by the wall bracket 18-001-979, and serviceable components align with the L68M service kit (L68M-KIT) for routine maintenance. This configuration minimizes downtime during upgrades or line changes.
The lubricator features a start point at 6 dm3/sec and a full flow capability of 175 dm3/sec (371 scfm). The built‑in flow sensor maintains a stable oil/air ratio across this range, ensuring consistent lubrication even as downstream demand changes. This reduces transient lubrication issues on variable-speed conveyors and multi‑station pick-and-place lines.
Yes. The micro fog technology provides fine mist lubrication ideal for long runs and complex pipework, minimizing oil carryover while delivering dependable coverage. Fitment to general pneumatic applications is supported by the aluminum body and compatible mounting options, making it suitable for varied plant layouts and automation cell configurations.
Maintenance is streamlined with a manual drain bowl and readily available service kit L68M-KIT. Optional bowls and compatible wall mounting accessories (18-001-979) support easy field servicing. Yoke assemblies (Y68A-6GN-N2N and N1N) provide flexible configuration for retrofit projects, reducing downtime and inventory complexity.
Operating temperature ranges from -20 to 80 °C with a maximum inlet pressure of 17 bar, suitable for most industrial environments. The body and bowl are aluminium, while elastomer components use nitrile rubber, balancing weight, durability, and chemical compatibility for common lubrication fluids. Always verify compatibility with your compressed air quality and borne condensation in the system.
