Model 20SS/A-40SS Pressure Washer Foaming Gun Kit

Model #A8047


Designed to work with a 3 – 6 GPM pressure washer using a long discharge hose (+100′). The Model 20SS/A40SS Combo Airless Foamer / Sprayer Kit is an airless foam and spray applicator featuring a chemical injector quick connected to the pressure washer discharge. This stainless steel venturi injection system 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 using a fan nozzle. Remove the fan nozzle for longer foam throw distance. Quick connect the fan pattern sprayer nozzle to apply a liquid chemical spray.
