The 2-Hose Low Volume Foam-All is a combination applicator for applying one or two chemical products as wet, clinging foam. This venturi injection system uses city water pressure (35 – 125 PSI) to draw and blend chemical concentrates into the water streams to create accurately diluted solutions. Precision metering tips are used to control chemical usage independently for each hose. The mixed solutions flows through the hoses to the "airless" foam wands which draw in atmospheric air to create and project foam in a fan pattern or narrow stream. Hoses can be used independently or simultaneously.
