Norgren L64C-NNP-EDN Oil Fog Lubricator - No Yoke
Part Number: L64C-NNP-EDN
Quick Summary
The L64C-NNP-EDN oil fog lubricator delivers precise lubrication for heavy-duty pneumatic cylinders and air tools. Inconsistent oil-air ratios and messy maintenance cut uptime and raise operating costs. CE conformity is standard in European pneumatic components, and robust enclosure designs typically meet common IP protection expectations. By supporting modular yoke plug-in systems, the L64C integrates with Olympian Plus platforms and reduces installation time. This yields predictable lubrication, easier service, and extended tool life in demanding environments. With a broad operating range and robust materials, the unit supports consistent performance from -20 to 80 °C in compressed-air lines. Designed for quick replacement with the closed-bowl design and compatible with Yoke assemblies like Y64A-4GA series, the unit minimizes downtime.

FAQs
The unit ships without a yoke (port size Without Yoke) but can be mounted with Y64A-4GA-N2N, N3N, and N1N yoke assemblies for plug-in modular mounting. A Wall Bracket 74504-50 is also compatible. This configuration enables quick installation, easy service access, and scalable mounting across multiple lines or cells in an automated plant.
Operating temperature is specified from -20 to 80 °C (-4 to 176 °F). The maximum inlet pressure is 17 bar. These ranges support reliable lubrication in varied industrial environments and allow standardization across many pneumatic circuits without special enclosures or cooling.
Flow is rated at 72 dm3/sec (153 scfm) with a start point at 1.5 dm3/sec. The unit uses oil fog lubrication to deliver heavier lubrication over short distances, ensuring a stable oil-air ratio across the operating range. This makes it suitable for large-bore cylinders, air motors, and high-demand tools.
Yes. The L64C-NNP-EDN is designed for heavier lubrication needs over short distances, such as large bore cylinders, air motors, and air tools. The closed-bowl design minimizes spillage, while the robust zinc alloy body and aluminium bowl provide durability in tough plant environments, helping maintain consistent lubrication and reducing unplanned downtime.
Plan for routine inspection of the closed-bowl unit and periodic replacement of elastomer seals. The modular yoke system simplifies mounting changes and service, while the Y64A accessory set and wall bracket offer flexible installation options. The design emphasizes minimal leakage and straightforward cleaning, supporting quick line reconfigurations during plant downtime or upgrades.
