What impact does differential air pressure have on moisture control?

Differential air pressure plays a significant role in moisture control because it directly affects the movement and circulation of air within a space. When there is a difference in air pressure between two areas, it can create a flow of air from high-pressure regions to low-pressure regions. This movement of air can carry moisture with it, influencing how humid or dry certain areas become.

For instance, in a building, if the pressure in one room is lower than in another, moist air from the higher-pressure area may be drawn into the lower-pressure area. This transfer can potentially lead to condensation and other moisture-related issues if not managed properly. Hence, understanding and controlling differential air pressure is crucial for maintaining optimal moisture levels and preventing issues such as mold growth or structural damage.
