Makinex DPW-4000-0A-HU-50 4,000 PSI 4.0 GPM Gas Powered Cold Water Dual Pressure Washer
Adjustable Pressure from 1,000 to 4,000 PSI
The Makinex DPW-4000-0A-HU-50 delivers up to 4,000 PSI at 4.0 GPM, with adjustable pressure that drops all the way down to 1,000 PSI for lighter work. That range means one machine handles everything from vehicle rinsing to concrete restoration, paint removal, and industrial degreasing. Powered by a Honda GX390 engine and a heavy-duty AR Triplex pump with gear reduction, this cold water dual pressure washer is the top-of-the-line commercial unit from Makinex. The 24-inch stainless steel rotary cleaner and 50ft 9in high-pressure hose give serious coverage on large surface areas.
Honda GX390 Power and Heavy-Duty AR Pump
The Honda GX390 is a proven commercial workhorse that delivers consistent torque across long operating hours. Makinex pairs it with an AR Triplex pump featuring gear reduction to 1,450 RPM, a thermal release valve, external bypass, and a built-in pressure gauge for precise PSI control. Vibration-reduction rubber engine mounts keep the unit stable during extended runs, reducing operator fatigue on full-day jobs. The 1.61-gallon fuel tank gives you longer run times between fill-ups compared to smaller units in the Makinex lineup.
Commercial Mobility and Storage
Despite its 236-pound weight, the DPW-4000 moves easily on front locking castor wheels and features a lifting eye for crane or forklift loading. The folding handles reduce the storage footprint, and the heavy-duty powder-coated frame protects internal components during transport. Contractors running concrete prep, heavy equipment cleaning, or large-scale property maintenance will find this unit covers ground quickly at 4.0 GPM while the dual pressure range eliminates the need to bring a second machine for lighter tasks.
