Norgren L64M-NNP-EDQ Micro Fog Lubricator - Without Yoke
Part Number: L64M-NNP-EDQ
Quick Summary
Norgren L64M-NNP-EDQ Micro Fog Lubricator delivers precise lubrication for general purpose pneumatic systems. Engineers often struggle to maintain a stable oil-to-air ratio across long runs and complex pipework, which can lead to uneven wear and downtime. The Olympian Plus family emphasizes modularity and reliability with a Plug-In yoke approach and a refined micro fog output, while this model remains yoke-free but remains compatible with Yoke assemblies for flexible installations. Designed for industrial environments, it supports rapid service with a quick fill option and a closed-bowl drain, helping maintenance teams reduce downtime and consumable waste. In practice, this combination of precise metering and robust construction translates into predictable lubrication performance and lower total cost of ownership.

Feature: Micro fog output with an integrated flow sensor maintains a nearly constant oil-to-air ratio across a broad flow range. Business Impact: Improves lubricant efficiency and reduces waste, delivering consistent performance in varying line speeds. Application: General pneumatic networks with long piping runs and mixed load profiles. Feature: Closed-bowl drainage design minimizes oil mist leakage and splash, supporting a cleaner work environment. Business Impact: Reduces housekeeping requirements and environmental risk, cutting maintenance time and costs. Application: Shop floors and assembly lines with tight space constraints. Feature: Rugged zinc alloy body with an aluminium bowl and nitrile elastomer seals. Business Impact: Enhanced durability, corrosion resistance, and reliable seals in harsh plant conditions. Application: Industrial facilities with challenging atmospheres and frequent cycles. Feature: Wide operating range including start point at 1.5 dm3/sec and maximum flow of 72 dm3/sec (153 scfm). Business Impact: Flexible sizing for both low and high-demand applications, enabling single-solution usage across multiple lines. Application: General purpose lubrication in diverse pneumatic circuits. Feature: Maximum inlet pressure rating of 17 bar. Business Impact: Compatibility with standard plant air systems without additional pressure conditioning. Application: Wide plant environments from compact cells to larger automation lines. Feature: Quick fill device option and compatibility with Yoke assemblies (Y64A-4GA-N3N/N2N/N1N) and wall mounting (74504-50). Business Impact: Faster maintenance, easier retrofits, and simpler installation in retrofit projects. Application: Field service, upgrades, and OEM integrations.

FAQs
The L64M-NNP-EDQ is supplied without a yoke by default but is compatible with optional Y64A-4GA-N3N/N2N/N1N yoke assemblies and a wall bracket (74504-50). For retrofit installations, mount the lubricator using the available wall bracket or integrate it into a compatible manifold and connect to standard compressed air lines up to 17 bar. Refer to the installation guide for step-by-step mounting and orientation guidance.
Key specs include a start point of 1.5 dm3/sec and a maximum flow of 72 dm3/sec (153 scfm), with a maximum inlet pressure of 17 bar. The lubricator is designed for compressed air and operates across a temperature range of -20 to 80 °C. The micro fog output and flow-sensing keep the oil/air ratio near constant across this range, supporting consistent lubrication.
Yes. The micro fog approach is ideal for long pipework and general-purpose pneumatic applications where fine mist improves lubrication uniformity along extended runs. The closed-bowl design reduces maintenance interruptions, and the modular accessory options enable easy adaptation to longer networks or plant expansions.
Certification details vary by market. The Olympian Plus family is designed to support industry-standard practices; always consult the datasheet (Datasheet PDF: https://cdn.norgren.com/pdf/en_8_240_400_L64M_L64C.pdf) and Installation Guide (https://cdn.norgren.com/pdf/IM_en_8_240_400_L64C_L64M.pdf) for location-specific CE, IP, or SIL-related requirements and to ensure proper installation and operation in your region.
Maintenance is streamlined by a closed-bowl design, quick-fill options, and the availability of a L64M service kit (L64M-KIT). Regular checks focus on seals (nitrile elastomers) and ensuring the flow sensor remains clean for accurate metering. The modular options and durable construction reduce downtime and lubricant waste, contributing to lower operating costs over the equipment life cycle.
