With the tumbling device the inside of up to 3 compressed gas bottles can be cleaned simultaneously. It is enclosed in a special steel housing to deaden the noise. The compressed gas bottles to be cleaned are filled with granite chippings, sealed and placed on the conveying rollers of the tumbling device. After closing the lid the rollers turn the compressed gas bottles around their own axis. In addition they swing up and down, so that the shoulder and base are also cleaned.
