The Zbreeze - Cooling Fan is designed to prevent stagnant hot air around nearby heat-producing components, drawing hot air away from a heat-producing component, and into the rack’s general circulating air. It is not intended to exhaust hot air from an entire rack or compartment full of equipment and should not be employed as a substitute for general rack or cabinet forced air circulation. Temperatures can increase to dangerous levels around closely-spaced components where local pockets of stagnant hot air are not exhausted by the overall air circulation in an equipment rack or compartment.
