Designed for 2.2–3.4 GPM pressure washers. The Model 10 Stainless Steel Combo Airless Foamer / Sprayer Kit is an airless foam and spray applicator featuring a quick connect chemical injector that attaches to a pressure washer outlet. This venturi unit draws and blends chemical concentrate into the water stream to create an accurately diluted solution. The solution then flows through the hose and gun to the airless foam wand which injects atmospheric air to create and project wet, clinging foam on to surfaces up close or at distances up to 20 feet with interchangeable fan and zero degree nozzles. Quick connect the fan pattern sprayer nozzle to apply non-foaming chemicals.
