Word for a system that exhales gas

Question

I'm looking for a word to describe a system that filters certain gases from a space and 'exhales' them outside. What verb can be used to describe that action?

Answer 1

I think you are looking for the word exhaust.

expel (gas or steam) from or into a particular place.

Exhaust systems are typically part of car engines, but can also be found on stoves or other gas-producing systems.
