FAQs
The HL84M-4GP-EDN is designed for both in-line and modular installation. Its G1/2 port size integrates with standard compressed air systems, and the closed-bowl drain simplifies maintenance. For retrofits, you can mount it inline along existing piping or in a modular configuration using compatible brackets, minimizing downtime during upgrades.
Expect a near-constant oil/air ratio across a broad flow range thanks to the integrated flow sensor. The device supports up to 73 dm3/sec (155 scfm) with a start point around 0.94 dm3/sec and a maximum inlet pressure of 20 bar, ensuring reliable lubrication for long-run piping and complex pneumatic circuits.
Yes. The operating temperature range is -34 to 80 °C (-29 to 176 °F), making it suitable for extreme environments commonly found in automated plants. The diecast aluminium body and nitrile seals provide robust resistance to temperature fluctuations and typical chemical exposure within industrial settings.
The product is Salt Spray compliant to ISO 9227, supporting corrosion resistance in challenging environments. It is designed for CE-ready installations in many regions and uses a durable ABS cover for impact resistance, aligning with common global industrial standards and installation practices.
With a closed-bowl design and high-impact ABS cover, maintenance intervals are reduced due to lower contamination risk and easier bowl changes. The micro fog approach minimizes lubricant consumption while maintaining effective lubrication, which translates to lower operating costs and improved uptime across high-demand pneumatic systems.
