1.3 SYSTEM VENTING REQUIREMENTS
VERY IMPORTANT: 1 SQUARE FOOT OF NET FREE VENT AREA PER 750 CFM
RECOMMENDED: 2 TO 4 SQUARE FEET OF INLET VENTS PER FAN
Venting plays a very signicant role in the performace of QuietCool fans. QuietCool recommends a mini-
mum of 1 SQ. FT. of venting for every 750 CFM in the QuietCool system. If an attic has at least 1:750 attic
venting, the QuietCool system will operate efciently and effectively. If an attic has less than 1:750 attic
venting, the system may not operate as efciently, or effectively, as it could with 1:750 attic venting. But
don’t worry, the system will still operate if there is not enough venting.
Insufcient venting is a very simple problem to x. Roong contractors can add extra venting to most
homes simply and easily. The most common types of venting is shown in the chart below.
