The Sanitmax SM4000 is a professional hot and cold water high-pressure washer engineered for industrial-grade cleaning power. Equipped with a high-efficiency diesel burner and gasoline engine drive, it delivers instant hot water up to 212°F (100°C)—no warm-up time required. With 4,000 PSI of adjustable pressure and up to 4.0 GPM of flow, it removes oil, grease, and grime from machinery, vehicles, and concrete faster and cleaner than cold water washers.
Designed for industrial and commercial professionals, the SM4000 combines a fuel-efficient stainless-steel burner, rugged steel frame, and smart safety control system for long-lasting reliability in the toughest environments—farms, factories, fleets, and construction sites.
