Norgren HL84C-4AP-MDN Oil Fog Lubricator - Salt Spray ISO 9227
Part Number: HL84C-4AP-MDN
Quick Summary
HL84C-4AP-MDN is an oil fog lubricator delivering precise lubrication for compact pneumatics and large-bore cylinders. In fast-moving production lines, inconsistent lubrication or downtime drains productivity. Its Salt Spray ISO 9227 compliance and wide operating range (-34 to 80 °C) support harsh environments. Designed for in-line or modular installation, it reduces retrofit time while maintaining a near-constant oil-to-air ratio. This combination delivers lower maintenance costs, longer component life, and predictable lubrication for large-bore cylinders, air tools, and motors. The unit's durable diecast aluminium body and nitrile elastomer seals resist contaminants and temperature cycling, while a manual drain and robust ABS cover simplify field servicing.

Flexible installation geometry is enabled by the Excelon Plus design, allowing in-line or modular installation to match existing layouts and minimize downtime. This translates to faster commissioning on new lines and simpler retrofits into aging systems. The integrated flow sensor maintains a near-constant oil-to-air ratio across varying flows. This improves lubrication consistency for large-bore cylinders, air motors, and pneumatic tools, reducing wear and improving repeatable performance. Salt spray ISO 9227 compliance provides corrosion resistance in challenging environments. Combined with a temperature range of -34 to 80 °C, the unit sustains performance in outdoors, wash-downs, and high-dust facilities. The ABS cover with high impact properties protects the unit in harsh workplaces. The diecast aluminium body and nitrile elastomer seals offer durability against contaminants and temperature cycling. 1/2" PTF port size aligns with common pneumatic fittings and the manual drain simplifies maintenance. In-line modular compatibility, plus a robust mounting pattern, makes retrofits straightforward. Operating up to 20 bar inlet pressure and a defined start point makes performance predictable for design engineers and procurement teams. The Excelon Plus family is designed to support large-bore cylinders and tooling, delivering measurable efficiency gains.
