Abstract
A pedestal which is open to the floor with provision for an air gap between the top of the pedestal and the electronic enclosure positioned thereabove. A plurality of air movers are mounted to the base of the enclosure and penetrate the pedestal. Air is drawn inwardly through the gap between the pedestal and the bottom of the enclosure and pumped into the enclosure through an opening in the bottom thereof. Noise from the fan inlet is constrained by a rubber bell and absorbed by the flooring materials. Direct transmission of inlet noise is blocked by the pedestal walls. Exhaust noise is constrained by a rubber nozzle and cone. The invention allows for a large volume of filtered air to pass through the enclosure with a minimum of incurred noise.
