An exhaust fan's primary method of operation is to pull in cooler air while simultaneously releasing heated air. Hot air is driven towards the fan by the airflow created by the rotating blades, where it is then ejected from space. By creating a vacuum effect, as hot air is expelled, colder air is drawn in to replace it, keeping the area ...
