Simpson ALH3425-S - 3600 PSI 2.5 GPM Gas Pressure Washer With Honda Engine

Power

The Simpson ALH3425-S

With a 196cc (5.5 hp) engine powering it, the triplex pump of this unit are capable of achieving a pressure of 3600 PSI (approximately 60 times greater than that of a standard garden hose) and a flow rate of up to 2.5 GPM (CETA-certified values). Corresponding to these values is a cleaning power of 9000 Cleaning Units.

The Honda GX200 engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.

Gasoline is stored in a steel fuel tank with a maximum capacity of 0.83 gallon.

Design & Handling

The Simpson ALH3425-S's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. Featuring an aluminum frame, this pressure washer boasts easy handling and exceptional durability, thanks to its corrosion-resistant properties and lightweight construction. The handle adds to the ALH3425-S convenience of transport.

At 78 lbs, this unit's substantial weight makes it quite a challenge for users to lift and maneuver, particularly on uneven surfaces where its heft can become even more apparent. Its 196cc Honda GX200 engine, the triplex pump and aluminum frame add up to a large chunk of the device's weight. Despite this, the presence of two 10" pneumatic wheels reduces the complexity of moving the ALH3425-S, even on rugged surfaces.

Main Features

The Simpson ALH3425-S

Along with the Simpson ALH3425-S itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

• Soap injection: Though lacking a dedicated soap tank, the device ensures detergent supply via a siphon hose. The Simpson ALH3425-S has an automatic soap dilution mechanism, which dilutes the detergent using a 7:1 ratio. Once a soap nozzle is connected, the pressure washer automatically blends the detergent with the water flow.
• Pressure hose: When not in use, the unit allows for tidy storage of the included 35 ft ⌀5/16" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
• Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
• Nozzles: The table below shows you the 5 included nozzles and the surfaces they're the most appropriate for.

Please note: The shapes of the nozzles depicted above are for illustration purposes and may vary. Symbols used include a red cross for 'Not recommended,' a green check for 'Suitable,' and an orange check for 'Use with caution.'
