Power

The Simpson ALH3228-S in use

The Simpson ALH3228-S

Powered by a 196cc (5.5 hp) engine, its triplex pump can deliver a pressure of 3400 PSI (around 57 times more than a standard garden hose) and a flow of up to 2.5 GPM (CETA-certified values). With these values combined, the Simpson ALH3228-S boasts a cleaning power of 8500 Cleaning Units.

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

Containing gasoline, the pressure washer's steel fuel tank can hold a maximum of 0.8 gallon..

Design & Handling

Featuring a wheelbarrow design, the Simpson ALH3228-S prioritizes maneuverability and stability, ensuring smooth handling and reliable functionality in demanding cleaning applications. Designed with an aluminum frame, this pressure washer combines lightweight construction with robust durability, offering corrosion resistance/strong> and effortless maneuverability for long-term reliability. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

Tipping the scales at 74 lbs, this unit's weight presents a notable challenge for users, especially when it comes to lifting and moving it, particularly over uneven ground. Its 196cc Honda GX200 engine, the triplex pump and aluminum frame are mainly responsible for its heavy weight. Despite this, the presence of two 10" pneumatic wheels reduces the complexity of moving the ALH3228-S, even on rugged surfaces.

Main Features

The Simpson ALH3228-S

Along with the Simpson ALH3228-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 automatic soap dilution mechanism of the Simpson ALH3228-S will dilute the detergent with a 7:1 ratio. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
  • Pressure hose: With a set of convenient hooks, the unit offers a practical solution for maintaining workspace order, allowing the included 25 ft ⌀5/16" high-pressure hose to be neatly stored when idle.
  • Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its steel wand.
  • Nozzles: Refer to the table below for details on the 5 included nozzles and their recommended surface applications.

    Simpson makes quality products. It has a Honda engine (like the old Briggs&Straton), which is bullet proof. The CAT Triplex pump is industrial grade. If you use this PW the average of 50hrs per year, it’s a ten year pump. If you take care of the pump, it’ll last much longer or you can use it, like I do, for light commercial use. The frame makes this machine light; I lift it in and out of my truck. Simpson customer service is a little lacking, but you will not call often. I think they are a very small company, that still uses paper and fax machines. I didn’t get all my nozzles; I literally got (4) 0 degree and (1) 15 degree. Called and they quickly apologized and said they send me the other 3 asap. ASAP took about 2 weeks, but I wasn’t in a rush. It’s pricey, but for the money, it competes with PW that run in the $850 to $950 range. Most other PW, in the price range, have either the CAT pump or the Honda or neither.

    + PROS: Honda engine, CAT Triplex pump, aluminum frame, big wheels, 3200psi
