Description

The A-iPower APW4200 is built to handle your toughest job. Powered by a reliable Senci 420CC Heavy Duty OHV gasoline engine that feeds into an AR (Annovi Reverberi) brand Tri-Plex Brass Head Pump, it delivers a powerful 4,200 PSI of cleaning power at 4.0 gallon per minute, that’s over 16,000 Cleaning Units to handle the toughest job

Zoom on the A-iPower APW4200

The A-iPower APW4200, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted or delicate 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 A-iPower APW4200 in use

The A-iPower APW4200

Its brass triplex pump, which utilizes an impressive 420 cc (14 hp) engine, may deliver a pressure of up to 4200 PSI (almost 70 times more than a standard garden hose) and a flow of up to 4 GPM. These values correspond to a cleaning power of 16800 Cleaning Units.

The Senci SC420 engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.

The fuel is stored in a tank, which can hold up to 1.7 gallon of gasoline.

Design & Handling

Thanks to its hand truck design and approximate dimensions of D32 x W26.5 x H36 in, the A-iPower APW4200 offers great mobility. The robust steel tubing frame guarantees longevity of the assembly. The handle adds to the APW4200 convenience of transport.

At 132 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 420 cc Senci SC420 engine, the triplex pump and steel tubing frame. However, the unit’s two 12" never-flat wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.

Main Features

The A-iPower APW4200 in use

The A-iPower APW4200

The A-iPower APW4200's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: The 50 ft ⌀5/16" high-pressure hose (5000 PSI rating), 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 table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
