The Pressure-Pro SH40004HH Dirt Laser is a portable commercial-grade hot water pressure washer designed for demanding cleaning applications where electric power is not available. It delivers 4000 PSI at 3.5 GPM and is powered by a reliable 389cc Honda GX390 gas engine with electric start.An industrial triplex ceramic plunger, direct-drive pump supplies consistent high pressure, while a thermostatically controlled 12-Volt DC diesel-fired burner heats water up to 250°F wet steam to break down grease, oil, and heavy buildup faster than cold water units. The stainless-steel wrapped 1/2 in. Schedule 80 heating coil ensures durability and efficient heat transfer.Built for commercial use, the unit features a rugged powder-coated steel frame with lifting point, integrated hose hooks, wand holder, and four large wheels for portability. A large 8-gallon diesel fuel tank provides extended burner run time. Includes heavy-duty spray gun, wand, quick-connect nozzles, and 50 ft. high-pressure hose, making it ideal for contractors, fleet washing, agriculture, and industrial facility maintenance.
