Norgren HL84M-3GP-MDN Excelon micro fog lubricator - ISO9227
Part Number: HL84M-3GP-MDN
Quick Summary
Norgren HL84M-3GP-MDN Excelon micro fog lubricator provides precise lubrication for general purpose pneumatic systems. Engineers often struggle with maintaining a steady oil-to-air ratio and frequent drain/disposal challenges. Salt spray ISO 9227 compliance and a robust ABS cover with high-impact properties support harsh environments. In-line or modular installation enables flexible deployment across lines, delivering reliability and measurable cost savings through reduced maintenance and oil waste. The design uses diecast aluminium bodies and nitrile elastomers for durability in extreme temperatures. A flow sensor maintains a nearly constant oil/air ratio across varying flows, starting from 0.94 dm3/sec.

Excelon Plus HL84M-3GP-MDN combines a rugged diecast aluminium body with a precise micro fog lubrication method, delivering high reliability in general pneumatic applications. This architecture reduces oil consumption while maintaining stable lubrication even as line speeds change, directly improving equipment uptime and reducing maintenance hours on production floors. In long or complex pipework, the fine mist travels farther with less oil carryover, cutting cleanup needs and oil waste. A built-in flow sensor maintains a consistent oil-to-air ratio over a wide flow range, improving lubrication predictability and simplifying maintenance planning across multi-branch networks. Inline installation or modular mounting supports compact plant layouts and fast retrofits, accelerating commissioning and lowering project risk. The combination of nitrate elastomer seals and diecast components withstands demanding environments, while ISO 9227 salt spray compatibility confirms corrosion resistance. With a maximum inlet pressure of 20 bar and a G3/8 port, it fits common plant air networks and supports easy replacement of legacy lubricators. The manual drain provides simple maintenance access, reducing service time and ensuring quick, clean operation.

FAQs
HL84M-3GP-MDN supports both inline and modular mounting, allowing flexible deployment across existing lines. Installers should align the G3/8 port with the compressed air feed, secure the diecast aluminium housing, and route the ergonomic manual drain for straightforward maintenance. The unit is designed for quick retrofits, minimizing piping changes while maintaining optimal oil-to-air distribution.
The lubricator delivers a maximum flow of 73 dm3/sec with a start point of 0.94 dm3/sec, ensuring reliable lubrication from startup through steady-state operation. A flow sensor maintains a nearly constant oil-to-air ratio across varying flows, supporting consistent performance on long pipe runs and multi-branch networks.
Yes. The Excelon Plus micro fog design excels in long or complex piping by delivering a fine mist that travels further with lower oil consumption. This reduces waste, simplifies maintenance, and maintains lubrication quality across extended networks, making it ideal for production lines with dispersed equipment and varied flow requirements.
HL84M-3GP-MDN is Salt Spray ISO 9227 compliant, reflecting its corrosion resistance in harsh environments. The unit also features a robust ABS cover and nitrile elastomer seals, contributing to reliability in demanding applications. No other formal certifications are listed in the provided data, but the build and materials are selected for industrial durability.
Expect reduced lubricant consumption due to the micro fog technique and a more stable oil/air ratio, which lowers waste and cleanup costs. Inline or modular installation speeds up commissioning, while the manual drain simplifies servicing. The combination of durable diecast aluminium construction and flow sensing leads to longer service intervals and improved uptime for production lines.
