Norgren HL84M-4AP-MDN Lubricator - Salt Spray ISO 9227
Part Number: HL84M-4AP-MDN
Quick Summary
Norgren HL84M-4AP-MDN lubricator provides precision micro fog lubrication for compressed-air systems in automation and manufacturing environments. Engineers often struggle with inconsistent oil distribution, wear on long pipe runs, and downtime caused by maintenance cycles. The Excelon Plus design is ISO 9227 salt spray compliant, supports in-line or modular installation, and uses a rugged ABS cover for high-impact environments. With a 1/2 inch port, manual drain, and an optimized oil-to-air ratio, this unit reduces maintenance time and boosts system availability across automation lines. The built-in flow sensor maintains a near-constant lubrication across changing flow, improving efficiency in general pneumatic applications. This combination translates to reduced wear, longer service intervals, and lower lifecycle costs.

FAQs
The HL84M-4AP-MDN supports in-line or modular installation using standard 1/2" PTF fittings. For retrofits, mount the valve on a stable surface near the compressor line, connect the half-inch ports to your feeder piping, and route the drain line to the collection point. Ensure pressure does not exceed 20 bar and maintain clean, dry air for best results.
HL84M-4AP-MDN uses Excelon Plus micro fog technology to generate a fine, controlled mist that achieves a consistent oil-to-air ratio across a wide flow range. This reduces oil consumption, minimizes misting, and extends component life, especially on long runs. The integrated flow sensor supports stable lubrication during demand fluctuations.
Yes. The design emphasizes micro fog lubrication with a stable oil distribution across extended piping. Its inline or modular installation minimizes space impact and simplifies retrofits, making it well-suited for automation lines with complex or lengthy piping where precise lubrication and reduced maintenance drive reliability.
HL84M-4AP-MDN is Salt Spray compliant to ISO 9227, reflecting its corrosion resistance in challenging environments. While it is designed for robust industrial use, verify CE marking or regional compliance with your purchasing team or distributor as part of your QA process to confirm broader regulatory alignment for your facility.
Regularly inspect the manual drain to ensure unobstructed drainage and verify the 1/2" port connections for leaks. The unit’s micro fog output and flow sensor reduce maintenance frequency by delivering consistent lubrication, but factors like air quality, oil type, and system pressure must be monitored to preserve performance and extend service life.
