Product Summary

Take on the toughest cleaning jobs with the Mi-T-M HSP-4004-3MGH Industrial Hot Water Pressure Washer. Engineered for professional contractors, agricultural operations, fleet maintenance, construction sites, and industrial facilities, this powerful hot water pressure washer delivers 4,000 PSI of cleaning pressure and 3.3 GPM of water flow to quickly remove grease, oil, mud, grime, and other stubborn contaminants from equipment, vehicles, machinery, concrete surfaces, and work areas. Powered by a dependable Honda GX390 OHV engine, the HSP-4004-3MGH provides reliable performance in demanding environments while maintaining easy starting and long service life. The industrial-grade AR triplex pump features a forged brass manifold, thermal relief valve, low-pressure detergent injector, and an external bypass system that protects components from excessive heat buildup during operation. A top-fired burner generates up to 294,000 BTUs per hour and delivers a temperature rise of up to 150°F above ambient conditions, with a maximum outlet temperature of 200°F, allowing hot water to break down grease and oils far more effectively than cold water cleaning alone. Built for durability, the reinforced powder-coated steel frame includes a center-balanced lift point for easier transport and rugged 13in. flat-free tires that handle uneven jobsite terrain. The unit comes equipped with a 50ft. steel wire-braided high-pressure hose, adjustable pressure insulated dual lance with trigger gun, and four quick-connect spray nozzles (0°, 15°, 25°, and 40°) for maximum cleaning versatility. Designed for heavy-duty commercial and industrial use, the HSP-4004-3MGH delivers the cleaning power, durability, and reliability professionals expect from Mi-T-M.
