Quick Summary

Norgren L64M-4GP-EDN micro fog lubricator provides precise lubrication for general-purpose pneumatic systems. It addresses common issues of oil/air ratio drift and inconsistent lubrication that can lead to wear, downtime, and reduced system performance. This model belongs to the Olympian Plus family and leverages a Plug-In yoke system for modularity, with a closed-bowl drain for low-maintenance operation. Designed for a wide operating range, it supports long pipework and high-flow applications while maintaining reliable lubrication. In practice, engineers benefit from predictable performance, easy installation, and compatibility with standard G1/2 ports, making it a strong fit for non-specialist automation lines and multi-point lubrication schemes.

Feature → Business Impact → Application: The L64M-4GP-EDN uses a micro-fog lubricator with a flow sensor that maintains a nearly constant oil-to-air ratio across a range of flows, delivering consistent lubrication and reducing component wear. This translates to lower maintenance costs and less downtime in high-cycle pneumatic systems, particularly where long pipe runs are involved in general automation lines. Application: suitable for general-purpose pneumatic circuits in manufacturing environments that require reliable lubrication without over-oiling, improving machine uptime and process stability. Feature → Business Impact → Application: The Plug-In Olympian Plus modular yoke enables quick field expansion and easy replacement, reducing commissioning time and training needs for maintenance staff. Application: ideal for modular systems and multi-station setups where future upgrades or reconfigurations are anticipated. Feature → Business Impact → Application: Closed-bowl drain minimizes oil spillage and entry of contaminants, supporting cleaner installations and easier servicing. Application: preferred in environments with strict cleanliness requirements or where splash-free operation is critical. Feature → Business Impact → Application: G1/2 port size ensures broad compatibility with standard pneumatic components and easy integration into existing manifolds. Application: fits most control panels and air preparation units without extensive re-plumbing. Feature → Business Impact → Application: Materials such as zinc alloy body and aluminium bowl provide durable construction for shop-floor reliability and long service life. Application: suited to demanding industrial environments where rugged hardware reduces maintenance intervals. Feature → Business Impact → Application: Flow rate of 72 dm3/sec (153 scfm) and start point of 1.5 dm3/sec support scalable lubrication for varying line pressures and loads. Application: appropriate for mid-to-high throughput lines with variable demand. Feature → Business Impact → Application: Compact, robust design with a 1.37 kg weight aids mounting in tight enclosures and on overhead lines. Application: streamlines installation in compact machines or retrofits where space is at a premium. Feature → Business Impact → Application: Availability of accessories such as silencers and mounting brackets improves system performance and reduces noise, enabling compliant installations and easier integration. Application: beneficial for facilities focused on worker comfort and regulatory noise limits. Across these features, customers gain predictable lubrication, easier maintenance, faster installation, and improved overall equipment effectiveness (OEE).

FAQs

This lubricator uses a standard G1/2 port and the Olympian Plus plug-in system, enabling straightforward integration with common air-handling manifolds. Pair with the T64T-6GB-P1N shut-off valve and T40B1800 silencer if noise reduction and easy shut-off are required during commissioning and maintenance.
The unit operates from -20 to 80 °C (-4 to 176 °F), which supports varied factory environments. At low temperatures, ensure lubricant viscosity remains within recommended limits; at high temperatures, monitor bowl integrity and elastomer performance to maintain consistent oil delivery.
Flow is rated at 72 dm3/sec (153 scfm) with a start point of 1.5 dm3/sec, providing a broad operating window for general applications. This allows a near-constant oil/air ratio across most operational regimes, improving consistency and reducing intermittent lubrication failures.
Yes. The micro-fog design and 72 dm3/sec flow support long runs and multi-point lubrication, while the Olympian Plus modular yoke system simplifies expansion and maintenance across stations, helping maintain uniform lubrication even as the line scales.
