Ventilating a building simply replaces stale or foul air with clean, fresh air. Although the ventilation process is required for many different applications, the airflow fundamentals never change Undesired air out, fresh air in. Sometimes you need an exhaust fan to perform a particular function, but it’s not clear which model to use or even what CFM is needed. If this is the case, you’ll need to do some fan specification work. Fan specification is not an exact science, but it can be done confidently when the fan application is understood.
