Compact and lightweight. It can replace high-pressure hydrocarbon-free gas cylinders and save laborious cylinder handling work.
Easy to operate with high automation. Simply connect the air source and turn on the power supply. Zero air will be generated once the catalytic temperature reaches the set value.
Reliable safety performance. Equipped with a two-stage over-temperature protection system inside, which automatically cuts off power when overheating occurs.
Multi-stage precision filters are built in to guarantee the air entering the catalytic chamber is dry, clean and oil-free, avoiding secondary contamination of hydrocarbon-free air.
All internal gas pipelines adopt internally and externally electropolished 316 stainless steel tubing.
Stainless steel drying tubes are adopted to avoid damage caused by aging and wear risks from disassembly. The modular design facilitates visual inspection and easy disassembly.
A vent valve is fitted. There is no need to disassemble the hydrogen outlet for pressure relief when replacing desiccants; just open the vent valve directly for quick and convenient operation.
