The 3 Gallon Pump-Up Foamer Pro is a portable foam applicator for applying foaming chemicals to any surface as high-quality, rich, clinging foam. This professional model projects foam in a wide fan pattern for quick, but still precise, foam coverage. The 3 Gallon Pump-Up Foamer Pro features a heavy-duty hose, trigger gun, and extension wand and combines the many advantages of foam cleaning with the familiar ease and portability of a typical pump-up sprayer. If compressed air is available, use the "quick charge" valve to eliminate pumping!
