Description
Zoom on the NorthStar 157134
In a nutshell, the NorthStar 157134 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted and fragile surfaces
- application of detergent and cleaning solutions
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The NorthStar 157134
Its triplex pump, which utilizes a powerful 389 cc (11.7 hp) engine, may deliver a pressure of up to 4000 PSI (almost 67 times more than a standard garden hose) and a flow of up to 3.5 GPM. These values correspond to a cleaning power of 14000 Cleaning Units.
The Honda GX390 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
A steel fuel tank with a maximum capacity of 1.6 gallon is used to store gasoline.
Design & Handling
The wheelbarrow design of the NorthStar 157134 grants mobility and stability to the unit. The strong steel tubing frame assures assembly longevity. The handle adds to the 157134 convenience of transport.
The unit's weight of 249 lbs renders its carrying and transportation challenging, as it is far from lightweight. Its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. However, the unit is manipulated smoothly thanks to its two 15" never-flat wheels, which play a key role in its maneuvrability.
Main Features
The NorthStar 157134
The NorthStar 157134'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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The NorthStar 157134 features an automatic soap dilution mechanism, that will dilute your detergent with a 15:1 ratio. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: The 50 ft 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 allows for an easy storage of the included classic ergonomic spray gun and its wand.
- Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.
15° | 25° | 40° | Soap | |
