Feature → Business Impact → Application: The HF84G-6GN-MM3 uses a 40 μm sintered polypropylene filter element that delivers high-efficiency water removal (>98%), reducing condensate carryover and downstream corrosion risks in automated assemblies. This translates to lower maintenance costs and longer life for valves and actuators in 24/7 production lines. Application: in automotive, food & beverage, and packaging lines where clean air is critical. Feature → Business Impact → Application: Diecast aluminium body and bowl provide robust mechanical durability in harsh environments, decreasing the risk of filter failure due to impacts or vibration. Application: robotics cell hydraulics interfaces and CNC automation where reliability matters. Feature → Business Impact → Application: G3/4 port size enables compatibility with common upstream plumbing while supporting a maximum inlet pressure of 20 bar, ensuring reliable flow and minimal pressure drop in demanding cycles. Application: high-volume pneumatic manifolds and machine tool cooling systems. Feature → Business Impact → Application: In-line installation or modular mounting with the Excelon Plus design reduces maintenance time because the bowl and element can be replaced quickly without disassembling surrounding components. Application: compact line stations and retrofit projects where service speed matters. Feature → Business Impact → Application: Manual drain simplifies maintenance in environments with intermittent condensate production, providing a predictable, low-cost solution for on-the-spot servicing. Application: remote or hard-to-access filter locations. Feature → Business Impact → Application: Nitrile elastomers and robust design deliver resilience to common lab and shop floor oils, supporting longer service intervals and consistent filtration performance. Application: general purpose pneumatic filtration in manufacturing and process industries. These design choices collectively improve uptime, enable faster maintenance, and support predictive maintenance programs while complying with ISO 9227 salt spray and other rugged-environment expectations. Keywords integrated include Excelon Plus filter, inline pneumatic filter, 40 μm filtration, G3/4 port, manual drain, diecast aluminium body, high-efficiency water removal, and harsh-environment filtration.

FAQs
The HF84G-6GN-MM3 is a G3/4 port inline filter with a 40 μm filter element and manual drain. It handles up to 20 bar maximum inlet pressure, provides a flow of 78 dm3/sec (165 scfm), operates from -40 to 80 °C, and uses diecast aluminium for the body and bowl with nitrile elastomers. This combination delivers robust filtration for general purpose pneumatic systems.
Yes. Excelon Plus filters are designed for in-line installation or modular setups, enabling flexible integration into compact pneumatic systems. The bowl and element can be removed together for faster servicing, reducing downtime in tight panel spaces and retrofit projects.
Maintenance centers on valve-ready service: the bowl and filter element can be removed together, and the unit uses a manual drain to evacuate condensate. The design supports quick cleaning and replacement, helping you minimize machine downtime while maintaining air quality. Salt spray resistance also supports long service life in demanding environments.
The Excelon Plus HF84G-6GN-MM3 is compliant with ISO 9227 for salt spray corrosion protection, ensuring durability in harsh environments. While specific industry certifications such as SIL or IP ratings are not stated, the unit’s materials and construction (diecast aluminium, nitrile elastomers) are chosen for rugged industrial use and long-term reliability.
The filter delivers measurable uptime gains through high-efficiency water removal (>98%), reduced maintenance time via fast bowl/element replacement, and reliable operation at up to 20 bar. These factors translate to lower total cost of ownership, fewer unscheduled outages, and improved consistency in pneumatic actuation across manufacturing lines.
