2-Way APV MMPR Concrete Sprayer

Model # 932617-V

The 2-Way APV MMPR Concrete Sprayer is a spray applicator for projecting 2 highly corrosive chemicals such as those used to remove concrete and for aluminum brightening. This acid-resistant system uses a cost-effective Flojet air-operated, double-diaphragm pump and water pressure to draw and blend chemical concentrate into the water stream or project neat chemical. A uniform spray is projected through the hose, wand and fan nozzle on to any surface. Alternate between 2 different concentrations or chemicals using ball valves.
