The Model 12 Compact Airless Foamer is a unique very low volume hose-end foam gun for diluting and applying foaming chemicals to any small or up close surface. This unit uses standard city water pressure to draw chemical concentrate from the attached bottle and blend it into the water stream. The accurately diluted solution flows through the foam wand to create a clinging, wet foam which can be projected in either a wider fan pattern or "adjusted" to a narrow pattern for longer foam throw up to 6 feet.
