If you are looking for superior cleaning and sanitizing performance in a portable and easy-to-use package, this is the unit. The GVC-1502 Vapor-Steam Cleaner heats tap water to produce a dry vapor-steam with an adjustable pressure of 0-90 PSI and an output temperature of 290F.

While the adjustable pressure allows the operator to release sufficient vapor-steam to thoroughly clean any surface without reduced visibility, the units chemical-injection system provides for additional cleaning power. The unit comes with a full assortment of cleaning tools and accessories to cover a wide range of applications.
