Up for sale are four empty steel and one empty aluminum Carbon Dioxide CO2 tank. These tanks are 5' tall, I believe they are 100# tanks. These come from a long time bar that has shut down. I am asking $250 each. They all look to be out of date for pressure test. You might be able to get them refilled, or you should be able to do an exchange at a prefill supplier with these tanks, or have it sent off to get re-certified. These can be used for soda carbonation and can also be used in a kegerator, homebrew, or draft beer tap system. Can also possibly be changed and refilled with Oxygen, Nitrogen, Nitrous, Argon, Helium, or Acetylene for welding. If the ad is up, the item is still available. Only serious buyers and reasonable offers please. If interested, please respond with a phone number I can reach you at.
