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:
- intense cleaning of tough, paintless surfaces
- cleaning of painted and fragile surfaces
- use of detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The NorthStar 157134
The NorthStar 157134's triplex pump, powered by a powerful 389 cc (11.7 hp) engine, can provide a pressure of up to 4000 PSI (approximately 67 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). The NorthStar 157134 thus has a cleaning power of 14000 Cleaning Units.
This gas-powered pressure washer’s Honda GX390 engine is started by a traditional 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. Its sturdy steel tubing frame provides longevity to the assembly. The handle adds to the 157134 convenience of transport.
At 249 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. A key role in its final weight is played by its 389 cc Honda GX390 engine, the triplex pump and steel tubing frame. However, its two 15" never-flat wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.
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: Even though the device doesn't have a soap tank, detergent is supplied by a siphon hose. The detergent is diluted with a 15:1 ratio by the NorthStar 157134's automatic soap dilution mechanism. When a soap nozzle is connected, the detergent will be added automatically to the water.
- 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 enables you to easily store the included classic ergonomic spray gun and its wand.
