Power

The Simpson ALH3225-S in use

The Simpson ALH3225-S

Using a 196 cc (6.5 hp) engine, its triplex pump delivers a pressure of up to 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). Together, the values result in a cleaning power of 8000 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s KOHLER SH265 engine.

The fuel is stored in a steel tank, which can hold up to 0.95 gallon of gasoline.

Design & Handling

The wheelbarrow design of the Simpson ALH3225-S grants mobility and stability to the unit. The aluminum frame grants the device a good durability, as it will not rust. The handle adds to the ALH3225-S convenience of transport.

The majority of users will be able to maneuver this unit easily, it only weighs 74 lbs. As its 196 cc KOHLER SH265 engine and triplex pump account for a good portion of that weight, Simpson's choice of an aluminum frame allows the device to stay at a reasonable weight. Since the ALH3225-S has a set of two 10" pneumatic wheels, it is still easily maneuvered and manipulated.

Main Features

The Simpson ALH3225-S in use

The Simpson ALH3225-S

Along with the Simpson ALH3225-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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The Simpson ALH3225-S includes an automatic soap dilution mechanism, which will dilute the detergent using a 7:1 ratio. When a soap nozzle is connected, the detergent will be added automatically to the water.
  • Pressure hose: The 35 ft ⌀5/16" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its steel wand.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
