Could one use Air Pressure as a form of stealth Propulsion in Space?

This is my first question here so I would like to apologize if this is sloppy or in the wrong place or the like. I have searched and found nothing that answers the exact question I think, so thought to ask. I also apologize if the tag is wrong as well.

Let's just hand-wave the heat issue of stealth in space for the sake of this question. The nation this question pertains to uses Nanocarbon tubes to turn the waste heat into what amounts to the background radiation of space or the energy used by the opponent's sensors.

Anyways, now that that's out of the way, here's what I'm looking for and the like:

Could one propel a ship using air pressure or through similar means without having to power up or the like to do so?

If yes, I would like an explanation, same for if not.

EDIT: Yes in space, sorry for not clarifying.
