Built in aeration system available for welded hoppers. Fully integrated into the structure of the hopper. Upper sheet serves as a plenum allowing air to be distributed evenly all the way around the cone. Channels direct air to center of cone ensuring complete air distribution. Ideally suited for fine grains where perforated tubes are not an option. It also allows larger centrifugal fans to be used for more drying capacity. Custom ducting is available.
