For big restoration jobs with a lot of areas to clean, the 10-Gallon Portable Foam Unit is ideal. There's no need to frequently stop and pump the unit, it connects to a standard 40-60 PSI air compressor and delivers constant, consistent foaming performance. It comes with a 20-foot 1/2-inch discharge foam hose that stores neatly on the integrated hose wraps when not in use. The transparent, natural-colored tank lets you see how much product is left inside. The hinged back plate gives you tool-free access to the internal components, so maintenance is a breeze. And the large recessed wheels it easy to maneuver the Portable Foam Unit around the job site.
