Fans remove ambient heat that rackmount components emit. Circulating new air into a wallmount cabinet or server cabinet helps maintain the optimum temperature for rackmount components. The Triple Fan Panel has three 105 CFM ultra quiet fans installed in a 3U panel. Simply mount the panel to the front or rear vertical rails of any 19 inch EIA Compliant rack and plug it in. This high volume fan panel will move 315 cubic feet of air per minute and with our specially designed cord that powers all three fans, it will only need 1 plug. These fan panels are top quality, pre-assembled and ready to install.
