Do oxygen making machines produce a carbon exhaust that people in that space can breathe?
Do ventilators exhaust carbon dioxide or carbon monoxide that is unhealthy for the inhabitants of an enclosed limited space where one is operating if that exhaust is not properly exhausted to the outside air?
The air is not exhausted…its returned to a filtering system with scrubbers that convert and recycle the air…same as on aircraft. The craft is equipped with return air fans that bring the ventalation back in through a filters, mostly charcoal, that remove the carbons from the air, then rehydrate the air and circulate it back out as purified oxygin. Its a little stale to breath but works really well. Love in Christ, ~J~
