Product Details

  • Powered by a ZONSEN GB420 electric-start engine, the MechMaxx HPW40HBT Hot Water Pressure Washer delivers dependable power and strong hot water cleaning performance for demanding washdown jobs. With 3,500–4,000 PSI pressure, 4.0 GPM flow, and water temperature up to 200°F, it helps remove grease, oil, mud, grime, and heavy buildup more effectively than cold water alone.
  • The unit is equipped with a triplex plunger pump, diesel-fired heating system, integrated control panel, and 245-gallon onboard water tank. This setup allows the washer to operate in locations where a direct water supply may not be available, making it suitable for farm, construction, industrial, fleet, and equipment maintenance applications.
  • Designed as a skid-mounted model, this pressure washer is built for truck beds, trailers, and utility platforms. Its rugged frame, onboard water tank, lift hook, and forklift slots support mobile cleaning jobs, easier loading, and convenient transport between worksites.

    NOTE!
  • This machine DOES NOT COME WITH OIL AND GASOLINE in the engine. Before starting, fill the engine with both oil and gasoline. Refer to the engine manual for details.
  • Maximum pump pressure is 4000 PSI, with the factory working pressure preset to about 3500 PSI.
