Norgren HL84C-4AP-EDN Oil Fog Lubricator - ISO 9227
Part Number: HL84C-4AP-EDN
Quick Summary
HL84C-4AP-EDN Excelon Plus oil fog lubricator delivers precise lubrication for heavy-duty pneumatic systems in manufacturing. Maintenance teams often struggle with maintaining a stable oil-to-air ratio and finding space for inline or modular mounting. This unit is ISO 9227 salt spray compliant for corrosion resistance and is built with a diecast aluminium body and a high-impact ABS cover to withstand rugged environments. By combining oil fog lubrication with a steady flow sensor, it reduces lubricant waste and improves component life, while offering installation flexibility and reliable performance in tight spaces. For engineers, this means lower maintenance costs and higher machine uptime through consistent lubrication and easier retrofits.

Feature: Inline installation or modular mounting with a compact 70 mm profile and 1/2 inch PTF port. Business Impact: Accelerates commissioning, reduces bespoke piping work, and enables scalable upgrades as line layouts evolve. Application: Ideal for automation cells and retrofits in constrained panels where space is at a premium. Feature: Oil fog lubrication provides heavier, consistent lubrication over short distances for large bore cylinders, air motors, and air tools. Business Impact: Improves reliability and extends tool life while reducing lubricant consumption. Application: Suitable for high-use pneumatic actuators and tool lines requiring robust lubrication. Feature: Flow sensor maintains a nearly constant oil/air ratio across a wide flow range (start point 0.94 dm3/sec to 91 dm3/sec). Business Impact: Delivers predictable cylinder movements and energy efficiency, minimizing fluctuations in performance. Application: Critical for packaging lines, presses, and systems with fluctuating demand. Feature: Salt spray compliant to ISO 9227 and durable diecast aluminium construction with a high-impact ABS cover. Business Impact: Enhanced corrosion resistance and rugged reliability in harsh environments, reducing maintenance frequency. Application: Factory floors and wash-down or outdoor areas where exposure to corrosion and impact is a concern. Feature: Engineered for easy maintenance and longevity with a closed bowl drain and lightweight design (0.53 kg). Business Impact: Lower total cost of ownership through fewer service interventions and straightforward bowl draining. Application: Continuous operation areas where quick servicing minimizes downtime.

FAQs
The HL84C-4AP-EDN supports inline installation or modular mounting thanks to a compact 70 mm footprint and a 1/2" PTF port. Use standard mounting brackets and orient the unit to optimize gravity-assisted bowl drainage. Ensure supply pressure stays within 20 bar and use correct piping to prevent pressure drop and line noise. This flexibility speeds up commissioning and simplifies future upgrades.
Core specs include a flow range from 0.94 dm3/sec at start to 91 dm3/sec (193 scfm), oil fog lubrication, 1/2 inch PTF port, closed-bowl drain, and a maximum inlet pressure of 20 bar. Operating temperature spans -34 to 80 °C. Materials are diecast aluminium with nitrile elastomer seals, ensuring durability in aggressive environments.
Yes. The Excelon Plus oil fog approach is designed for heavier lubrication over short distances, making it suitable for large bore cylinders, air motors, and frequent-use air tools. The integrated flow sensor maintains a stable oil-to-air ratio across operating conditions, supporting consistent performance and reduced wear on high-demand components.
The HL84C-4AP-EDN features ISO 9227 salt spray compliance for corrosion resistance, coupled with robust diecast aluminium construction and a high-impact ABS cover. These characteristics enhance reliability in challenging environments and align with common industrial corrosion and durability expectations.
The unit’s flow sensor maintains a constant oil/air ratio, reducing lubricant waste and improving predictability of cylinder movements. The closed-bowl design simplifies drainage and maintenance, while its modular compatibility supports faster upgrades and reduced downtime, delivering tangible ROI through extended equipment life and lower maintenance costs.
