Take the tour ×  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?
share|improve this question Like a hot gas filtration system?
What kind of gases? In medicine, there are anesthetic gas
scavenging systems. Can you provide a little more context? –

it is difficult to answer to this question. –  user19148 May 5

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.  share|improve this answer add comment  Your Answer
