Fan, blower door testing.

Gaseous suppression systems are effective for protecting valuable assets without damaging them, however, that’s only if the room can retain the concentration for the time needed to suppress a fire. A door fan test, also known as a room integrity test, is designed to predict an enclosure’s retention time in the event a suppression system is discharged. Blower door testing will measure the total leakage and determines how long an agent would stay in an enclosed space.​
