We have 2 blasting machines which takes off old paint from the cylinders and modern painting line what allows us regenerate 22000 of cylinders per week. If need this amount can be bigger if we start work in four-shift work system.

  • cleaning of the outside surface of gas cylinders in shot blasting machine,
