Beverage-Air Kegerator...."commercial grade" kegerator used for home bar setup. This unit comes with 2 CO bottles and all of the hoses and complete cleaning kit. This unit is commercial grade and has the fan assembly that blows the refrigerated air up into the tap cylinder so the entire line stays cold. It also has the top side slide open door to reach in a stored the pint glasses on a shelf just above the keg. As for keg sizes it will hold 1/6 up 1/2 kegs. I purchased the unit new in 2007-2008 and I'm the only owner. The only reason I'm getting rid of it is I don't drink beer anymore and I'm redoing my counter tops so I want to do something else with the space. Even though this unit is about 18 years old it still blows cold and new one goes for around $2,500. Don't waste the money on a new one when you can buy this for less than 1/2 the price.
