The Beverage Air DD50 kegerator is designed for commercial or home use. Has a two 1/2 keg capacity. This unit is forced air cooled, which means cold air is blown around the unit to keep keg beer ice cold for dispensing. Includes a single 3-inch double faucet and insulated draft beer tower. The tower is adapted to have a continuous source of cold air channeled into it to dispense beer at its coldest.
