The Blue Mule Compact Foam-All 25B is a unique MEDIUM VOLUME hose-end foam gun for diluting and applying foaming chemicals to any 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 which injects atmospheric air to create a wet, clinging foam which is then projected on to surfaces up close or at distances up to 12 feet. Quick disconnect the chemical assembly to rinse.
