Norgren L68C-6GP-ERN Oil fog lubricator - Plug-In System
Part Number: L68C-6GP-ERN
Quick Summary
Norgren L68C-6GP-ERN oil fog lubricator is designed to deliver precise lubrication for pneumatic systems in medium-to-heavy automation environments. Operators often struggle to maintain a stable oil-to-air ratio when flows vary, leading to uneven wear or contamination in downstream actuators. This Olympian Plus family product supports robust reliability with a modular, plug-in yoke system, a closed aluminium bowl, and a flow sensor for a near-constant oil/air ratio. When selecting lubrication for high-demand lines, consider compatibility with G3/4 porting, wide operating temperature, and durable elastomer seals. By combining modular installation with proven lubrication technology, you can reduce maintenance intervals and improve line uptime while meeting industry expectations for performance and reliability.

FAQs
What mounting options and clearances are required for a G3/4 lubricator in a standard panel or wall mount? This unit supports Yoke assemblies and wall brackets, with a compact aluminium body and clear bowl access. Confirm compatibility with your chosen air preparation kit and ensure adequate space for the closed-bowl drain and service access. Regularly verify seal integrity of nitrile elastomer components to prevent leaks.
Flow starts at 6 dm3/sec and scales up to 175 dm3/sec with a rated 17 bar inlet. This enables stable oil delivery across varying loads, reducing lacquered oil residues and inconsistent lubrication that can shorten tool life. In large bore cylinders and air motors, the sensor-controlled flow maintains consistent oil-to-air ratios, improving wear protection and process stability.
Yes. The oil fog approach provides heavier lubrication where short-distance delivery is needed, which is common in large-bore cylinders and air-powered tooling. Its robust aluminium construction, closed-bowl design, and compatible G3/4 porting support reliable operation in demanding automation segments while minimizing maintenance overhead.
Typical installations rely on industry-standard safety and quality practices for pneumatic components. When sourcing, verify CE conformity and compliance with local electrical and machinery safety standards as applicable in your region. Always consult the supplier’s datasheets and installation guides to ensure alignment with your plant’s regulatory requirements.
Maintenance benefits include availability of a service kit (L68C-KIT), a closed-bowl design to minimize spill risk, and a modular plug-in system that reduces downtime during service or upgrades. ROI advantages arise from stable lubrication, extended component life, and lower maintenance frequency, especially in high-cycle lines and heavy-use pneumatic stations.
