Zoom on the NorthStar 157127

The NorthStar 157127 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • broad cleaning of hard surfaces, vehicle washing, and surface preparation for painting
  • gentle cleaning of delicate surfaces, and low pressure cleaning of larger areas
  • using cleaning solutions, and rinsing surfaces to remove residue

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 NorthStar 157127 in use

The NorthStar 157127

Powered by an impressive 389cc (11.7 hp) engine, its triplex pump can deliver a pressure of 4200 PSI (around 70 times more than a standard garden hose) and a flow of up to 3.5 GPM (values claimed by the manufacturer). With these values combined, the NorthStar 157127 boasts a cleaning power of 14700 Cleaning Units.

Starting the Honda GX390 engine of this gas pressure washer involves using a conventional pull-start method.

The pressure washer's steel tank has a maximum capacity of 1.5 gallon for storing gasoline.

Design & Handling

The NorthStar 157127's wheelbarrow-style design enhances both mobility and stability, enabling seamless navigation and consistent performance, even on rugged terrain. The steel tubing frame's robustness ensures the assembly's longevity, maintaining stability and protecting internal components, even in the harshest environments. The handle adds to the 157127 convenience of transport.

With its weight clocking in at 145 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. Its 389cc Honda GX390 engine, the triplex pump and steel tubing frame add up to a large chunk of the device's weight. Nonetheless, the addition of two 10" never-flat wheels simplifies maneuvering the 157127, even across rough ground.

Main Features

The NorthStar 157127 in use

The NorthStar 157127

The NorthStar 157127 comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. Featuring an automatic soap dilution mechanism, the NorthStar 157127 ensures detergent is mixed to the specified ratio of 15:1 for optimal cleaning results. Upon attaching a soap nozzle, the pressure washer seamlessly integrates the detergent into the water flow.
  • Pressure hose: With a set of convenient hooks, the unit provides a convenient way to store the included 50 ft ⌀3/8" high-pressure hose when not in use, keeping it organized and readily accessible.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The table below shows you the 4 included nozzles and the surfaces they're the most appropriate for.
