Solvent Saver hose/gun cleaner - Simple, easy-to-use cleaner saves solvent (up to 86% savings!), which reduces VOC emissions. A finely atomized blast of solvent travels through the hose and gun fluid passages. Operated with compressed air, metering permits adjustment of the air/solvent mix, and tanks are equipped with a safety valve. Not suitable for use with chlorinated solvents, such as 1,1,1 trichloroethane or methylene chloride.
