Gas replacement box / Gas replacement box

Gas replacement  box

Gas replacement box can prevent people from choking to death in the fire as much as possible.It will be installed in a small space that is not easy to catch fire and has water. When the fire just occurs, the Gas replacement box will draw the surrounding oxygen and compress it. People trapped in the fire can take out the breathing mask from it to get oxygen, and can choose to release CO2 to fill the toilet, so that the toilet is not easy to invade by the fire.
It can provide both short-term oxygen supply and continuous oxygen supply, which makes its use more flexible.
