Compact and lightweight; it replaces high-pressure hydrocarbon removal gas cylinders and eliminates laborious cylinder handling.
Simple operation and high automation level. Simply connect the air supply and turn on the power switch; zero air will be generated once the catalytic temperature rises to the set value.
Reliable safety performance. A two-stage over-temperature protection system is built-in, which cuts off power automatically upon overheating.
Multi-stage precision filters are equipped internally to ensure the air entering the catalytic chamber is dry, clean and oil-free, preventing secondary contamination of hydrocarbon-free air.
All internal gas pipelines adopt internally and externally cleaned 316 stainless steel tubing.
The instrument adopts a PSA (Pressure Swing Adsorption) water removal unit with automatic regeneration, requiring no replacement of consumables and realizing fully maintenance-free operation.
The instrument supports functions including operating parameter query and cumulative runtime recording.
RS485 communication is available as an optional configuration.
