3.5 Pressurized Systems
In pressurized systems an air replacement system consisting of a fan and maybe a heater system adds replacement air directly to the booth in lieu of drawing the air thru a filter door. These systems are difficult to balance, but once the fundamentals are understood the balancing is very simple. Let us look at a system that is incorrectly balanced.
