FAQs
Yes. HF84G-6GN-MD3 supports both inline and modular installation, enabling straightforward Retrofit in existing circuits without extensive piping changes. The G3/4 port size and compact diecast aluminium housing simplify integration with standard pneumatic manifolds, while the bowl-and-element removal design speeds servicing, reducing downtime during filter changes.
The filter uses a 40 μm element and delivers high moisture removal efficiency (>98%). It supports up to 165 scfm (78 dm3/sec) at a maximum inlet pressure of 20 bar, making it suitable for high-flow pneumatic networks while protecting downstream actuators from water and particulate contamination.
Absolutely. The HF84G-6GN-MD3 operates from -40 to 80 °C and is ISO 9227 salt spray compliant, which provides durability in harsh environments, including coastal facilities or processes with elevated humidity. The diecast aluminium body plus nitrile elastomers are chosen for reliability in demanding settings.
This filter is designed to meet industry expectations for compressed air filtration and durability, including ISO 9227 salt spray testing for corrosion resistance. While specific regional certifications may vary by market, the Excelon Plus range emphasizes standards-based performance and robust field reliability.
The element-removal-with-bowl design minimizes maintenance time, allowing rapid filter changes without dismantling upstream components. Combined with high filtration efficiency and durable materials, this reduces scheduled downtime, extends component life, and lowers long-term maintenance costs, delivering measurable ROI in high-demand production lines.
