Machine Character

1. Easy use, only pure air input, power on the button, pure nitrogen gas is produced. Our machine could be used continuously. Also could be used intermediately. 

2. Electrolysis cell reaction area is large, cell temperature is low. Longer lifetime.

3. Our machine has liquid anti return apparatus, could guarantee safety use.

4. While working, machine has equipped auto gas drain apparatus, also have manual drain switch( not used for GC), gas produced on demand, stable output flow rate, after power off electricity, machine could automatically close gas system.
