Our 12 ft. Spray Bar is designed to treat very large areas quickly and accurately.  The sprayer is operated by an air driven pump which draws the SIL-ACT® Silane Solution directly from the tote, drum, or pail. Each spray bar has 24 spray tips, the default tips average .8 GPM. To extend the life of your equipment it is recommended that the pump lines, spray bar and spray gun be flushed with SIL-ACT® Equipment Cleaner, after each use.
