Description
Zoom on the Powerhorse 115179
The Powerhorse 115179, a commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:
- broad cleaning of hard surfaces, vehicle washing, and surface preparation for painting
- gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
- applying detergent and cleaning solutions, and rinsing surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Its triplex pump, which utilizes a powerful 420cc engine, may deliver a pressure of up to 4400 PSI (almost 73 times more than a standard garden hose) and a flow of up to 4.2 GPM. Corresponding to these values is a cleaning power of 18480 Cleaning Units.
The engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.
The pressure washer's tank has a maximum capacity of 1.72 gallon for storing gasoline.
Design & Handling
Featuring a wheelbarrow design, the Powerhorse 115179 prioritizes maneuverability and stability, ensuring smooth handling and reliable functionality in demanding cleaning applications. The steel tubing frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
At 142 lbs, we can't really say that the unit is lightweight, and manually lifting or transporting it could be a significant challenge for users, especially if they need to move it frequently or navigate over uneven terrain. The major reasons for its heavy weight are its 420cc engine, the triplex pump and steel tubing frame. However, the incorporation of two 12" pneumatic wheels makes navigating the 115179 less cumbersome, even on uneven terrain.
Main Features
The Powerhorse 115179'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: The pressure washer comes equipped with a dedicated tank to store detergent. The automatic soap dilution mechanism of the Powerhorse 115179 will dilute the detergent with a 15:1 ratio. The detergent is automatically mixed with the water flow by the pressure washer when a soap nozzle is connected.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 50 ft ⌀3/8" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
- Spray gun and wand: A side hook allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: Refer to the table below for details on the 4 included nozzles and their recommended surface applications.
