Simpson Aluminum ALH3425 3,400 PSI 2.5 GPM Cold Water Gas Aluminum Pressure Washer
Simpson Aluminum ALH3425, 3,400 PSI Cold Water Pressure Washer
The Simpson Aluminum ALH3425 pushes 3,400 PSI at 2.5 GPM with a Honda GX200 engine, built on a lightweight aluminum frame for easy transport between job sites. This output level suits concrete cleaning, wood deck stripping, equipment degreasing, and property maintenance where higher pressure speeds up the work.
Honda GX200 with AAA Industrial Pump
Honda's GX200 engine delivers dependable starting and steady power for all-day operation with low oil shutdown built in. The AAA industrial triplex plunger pump converts that engine power into consistent 3,400 PSI output without the pressure drops that signal pump fatigue on lesser units.
Built Light, Built to Last
The aluminum frame shaves pounds off the total weight, making the ALH3425 easier to load into trucks, haul up ramps, and maneuver on job sites. Aluminum also resists the rust that eats through painted steel frames after months of wet use and outdoor storage.
