Feature: Micro fog lubrication delivers an exceptionally fine oil mist at modest flow rates, controlled by an integrated flow sensor. Business Impact: maintains a near-constant oil/air ratio across a wide range of flows, reducing lubricant waste by up to 30–50% and lowering consumable costs. Application: ideal for general pneumatic systems and long or complex pipework where precise lubrication improves cycle times, reduces wear, and extends spare-part intervals. The design supports continuous operation across the Excelon Plus family, aligning with lean maintenance practices. Feature: Flexible installation options with inline or modular configurations. Business Impact: cuts commissioning time by up to 40%, simplifies retrofits, and preserves valuable floor space in busy plants. Application: perfect for line upgrades or new builds in manufacturing cells where a compact, scalable lubrication solution is desirable and downtime during changeovers is minimized. Feature: Rugged diecast aluminium body and bowl with nitrile elastomer seals, plus a high-impact ABS cover. Business Impact: enhanced durability reduces unscheduled maintenance and extends service intervals in harsh environments and high-vibration applications. Application: well-suited to outdoor or humid facilities and factory floors where reliability is critical. Feature: Precise specifications include G1/2 port size, manual drain, maximum inlet pressure 20 bar, operating temperature -34 to 80 °C, and flow 73 dm3/sec with a start point of 0.94 dm3/sec. Business Impact: straightforward integration with standard plant air lines and predictable lubrication performance across thermal and pressure variations. Application: compatible with most general pneumatic networks and new equipment installations seeking robust lubrication control. Feature: ISO 9227 salt spray compliance and the Excelon Plus lineage deliver reliable corrosion resistance and proven long-term performance. Business Impact: supports compliance with industrial reliability standards while delivering consistent lubrication for compressed air systems. Application: suitable for a wide range of general pneumatic lubrication tasks in demanding industrial environments.

FAQs
HL84M-4GP-MDN supports both in-line and modular installation configurations, enabling flexible integration into existing pipelines or modular lines. To install inline, connect the G1/2 port to the compressed air line using standard fittings and secure the unit to a support surface. For modular setup, mount the lubricator adjacent to the controller or purifier unit and link via a short, appropriately rated feed line. Both approaches minimize footprint and streamline maintenance access, which helps reduce commissioning time and changeover downtime.
Key specifications include a G1/2 port, manual drain, maximum inlet pressure of 20 bar, and an operating temperature range of -34 to 80 °C. The unit delivers a flow of 73 dm3/sec (155 scfm) with a start point around 0.94 dm3/sec. The integrated flow sensor maintains a near-constant oil/air ratio across a broad flow range, contributing to predictable lubrication, reduced oil consumption, and improved component life.
Yes. The micro fog technology and Excelon Plus design are intended for general pneumatic systems, including long and complex pipework where steady lubrication is critical. The G1/2 port, wide operating temperature, and robust housing support reliable performance across various layouts. This makes it well suited for manufacturing lines, automotive assembly, and processing plants that demand consistent lubrication with minimal maintenance.
The HL84M-4GP-MDN is ISO 9227 salt spray compliant, indicating robust corrosion resistance suitable for demanding environments. While other certifications such as SIL, CE, or IP ratings are not specified in the provided data, the ISO 9227 compliance supports reliability in humid or aggressive environments and aligns with common industrial expectations for lubrication components in pneumatic systems.
The integrated flow sensor and micro fog lubrication yield a near-constant oil/air ratio, reducing lubricant waste and extending service intervals. The diecast aluminium body and high-impact ABS cover enhance durability, lowering unscheduled maintenance. Inline or modular installation reduces commissioning time, and the reliable performance of the Excelon Plus family helps stabilize maintenance budgeting and boost overall plant uptime.
