Description

Zoom on the Rainier RPX3200

The Rainier RPX3200 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • use of 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.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s engine.

Gasoline storage is facilitated by a fuel tank with a maximum capacity of 0.9 gallon.

Design & Handling

With its hand truck design and approximate dimensions of L21 x W19.5 x H39 in, the Rainier RPX3200 provides 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 all add up to a substantial part of that weight. Nethertheless, thanks to its two 12" never-flat wheels, the RPX3200 remains very easy to manipulate and maneuver.

Main Features

The Rainier RPX3200 in use

The Rainier RPX3200

The Rainier RPX3200 comes with a spray gun, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: A safe detergent storage is facilitated by a 0.5 gal tank. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • Pressure hose: The 25 ft ⌀5/16" high-pressure hose (3100 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: A side hook allows for an easy storage of the included classic ergonomic spray gun.
  • Nozzles: The table below shows you the 5 included nozzles, as well as the surfaces they're the most appropriate for.
