DeWalt DXPW3123 3100PSI Gas Pressure Washer

Description

Zoom on the DeWalt DXPW3123

In summary, the DeWalt DXPW3123 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • spot cleaning of hard, paint-free surfaces and out-of-reach areas
  • cleaning of painted and frail surfaces
  • use of detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The DeWalt DXPW3123's axial cam pump, powered by the brand new, specially built for pressure washers, Honda GCV170 (opens in a new tab) engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.3 GPM (CETA-certified values). The DeWalt DXPW3123 thus has a cleaning power of 7130 Cleaning Units.

The 166 cc engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.24 gallon.

Design & Handling

The DeWalt DXPW3123 offers superb mobility, with a hand truck design and approximate dimensions of D23.8 x W18 x H35.8 in. The robust steel frame guarantees longevity of the assembly. The handle adds to the DXPW3123 convenience of transport.

With a weight of 56 lbs, the unit can be easily maneuvered by most users. Its 166 cc Honda GCV170 engine and steel frame account for a good chunk of that weight. However, the two 12" never-flat wheels allow the DXPW3123 to be easily manipulated and maneuvered.

Main Features

The DeWalt DXPW3123's package includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent storage is ensured by a dedicated tank. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: The included 25 ft ⌀1/4" high-pressure hose can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun and wand: Both the classic ergonomic spray gun and its wand may be conveniently stored in a side hook.
  • Nozzles: The 4 included nozzles, and the respective surfaces they’re appropriate for, are listed in the table below.

It boasts seven manufacturing facilities in the U.S. Though known mainly for professional-grade corded-electric and battery-powered hand tools, the company has also begun to offer some outdoor power equipment as well, such as leaf blowers and string trimmers. DeWalt gas-powered washers are manufactured by FNA, and electric washers are manufactured by Stanley Black & Decker.
