HL84M-4AP-EDN Norgren Micro Fog Lubricator - ISO 9227
Part Number: HL84M-4AP-EDN
Quick Summary
HL84M-4AP-EDN is a micro fog lubricator for compressed air systems used in general pneumatic automation. In long piping runs and harsh environments, maintaining a stable oil-to-air ratio is challenging, risking wear and inconsistent performance. Salt spray resistance and wide temperature capabilities are supported by ISO 9227 compatibility and a wide operating range from -34 to 80 °C, aided by a robust closed-bowl design. Inline installation or modular installation options and precise flow management deliver uptime benefits and predictable maintenance budgets, with Excelon Plus as the platform for scalable automation.

FAQs
HL84M-4AP-EDN supports both inline and modular installation, simplifying retrofits and new builds. Connect to a 1/2" PTF port on the compressed air line, ensure the supply is within the 20 bar maximum, and mount the unit so the closed bowl is protected from splashes. The included flow sensor helps maintain a stable oil/air ratio across varying line flows, reducing maintenance surprises in long pipework.
The lubricator operates from -34 to 80 °C (-29 to 176 °F) and supports a maximum inlet pressure of 20 bar. It uses compressed air as the medium and features a 1/2" PTF port. These specs enable use in demanding environments while maintaining reliable lubrication performance.
Key metrics include a flow of 73 dm3/sec (155 scfm) with a start point of 0.94 dm3/sec, and a micro fog lubrication type designed for efficient oil usage. The integrated flow sensor maintains a near-constant oil/air ratio across flow ranges, enhancing consistency and reducing waste in general pneumatic applications.
Yes, HL84M-4AP-EDN is salt spray compliant to ISO 9227, indicating good corrosion resistance in humid or coastal environments. The body and bowl are diecast aluminium with nitrile elastomer seals, and the cover is ABS with high impact resistance, providing robust protection in tough industrial settings.
The closed-bowl design minimizes oil splash and simplifies maintenance, while the micro fog approach reduces oil consumption relative to traditional lubricators. The option for inline or modular installation speeds up commissioning and upgrades, improving equipment uptime and reducing lifecycle costs in general pneumatic systems.
