The Pail/Jug Mount Uni-Body A-25 Airless Foamer is a convenient container-mounted chemical applicator that projects a medium volume of wet foam onto any surface at distances up to 6 feet, without compressed air. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw chemical concentrate directly from the container and blend it into the water stream to create an accurately diluted solution. The solution then flows through the discharge hose to the "airless" foam wand which draws in atmospheric air to create and project wet, clinging foam.
