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

In a nutshell, the A-iPower APW4200 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:

  • spot cleaning of hard, unpainted surfaces or high reach areas
  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail 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

Using an impressive 420 cc (14 hp) engine, its brass triplex pump delivers a pressure of up to 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Together, the values result in 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.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.7 gallon.

Design & Handling

The A-iPower APW4200 offers superb mobility, with a hand truck design and approximate dimensions of D32 x W26.5 x H36 in. 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 device’s two 12" never-flat wheels play a key role in its maneuverability, as they allow it to be manipulated smoothly.

Main Features
