Water Cannon's professional foam jet kit (part #14.0289) is a high-pressure foam system tool than shoots more than 20 feet of dense foam that literally sticks to surfaces, instantly conserving chemical use, and has detergent suction power, even at more than 30 feet of vertical height. The Foam Jet Injector, with a fully variable spray pattern from a straight stream up to 50 degrees, works on any pressure washer application up to 5,000 psi with a maximum flow rate of 5.6 gpm.
