Description

Zoom on the Rainier RPX3200

The Rainier RPX3200, 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 tough, paintless surfaces
  • cleaning of painted or delicate surfaces
  • applying detergent and cleaning solutions

Ahead are presented its power characteristics and design, its main features and any other additional features.

Power

The Rainier RPX3200 in use

The Rainier RPX3200

Using an impressive 212 cc engine, its aluminum axial cam pump delivers a pressure of up to 3200 PSI (roughly 53 times more than a standard garden hose) and a flow of up to 2.5 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 8000 Cleaning Units.

This gas-powered pressure washer’s engine is started by a traditional pull-start mechanism.

Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.

Design & Handling

Thanks to its hand truck design and approximate dimensions of L21 x W19.5 x H39 in, the Rainier RPX3200 offers great mobility. The robust and sturdy steel tubing frame offers longevity to the assembly. The foam-padded fixed handle adds to the RPX3200 convenience of transport, while offering a comfortable grip.

Most users can maneuver this model easily, as it weighs just 64 lbs. Its 212 cc engine and steel tubing frame account for a good chunk of that weight. Since the RPX3200 has a set of two 12" never-flat wheels, it is still easily maneuvered and manipulated.

Main Features

  • Pressure hose: The included 25 ft ⌀5/16" high-pressure hose (3100 PSI rating) can be neatly stored on the unit when idle thanks to a set of convenient hooks.
  • Spray gun: The included classic ergonomic spray gun can be easily stored in a side hook.
