|Safety devices for technical gases give reliable protection against reverse flow of gas and flashbacks for the pressure regulator, tapping points from pipe line systems and individual cylinders, hoses, equipment and flame cutting machines as well as gas supply stations. They prevent the entry of air or oxygen into supply if there is a backfire. Bulit-in fliters give protection against impurities and guarantee long consumable equipment lives.|
