The Steam Clean Car Wash Machine Super Max™ 12800 differing from other systems in its versatile heating methods, the Super Max™ 12800 offers the same tri-temperature technology offered in many Super Max™ pressure washers. Cold water, hot water, and wet steam can be used independently for varying applications, with wet steam temperatures up to 330°F providing the ideal cleaning power for steam car wash applications. A high pressure level of 1000 psi and moderate flow rate of 2 GPM enable efficient cleaning without damaging vehicle surfaces.
