Power
Utilizing an impressive 212cc engine, this machine's axial cam pump can deliver a pressure of 3400 PSI (around 57 times stronger than a standard garden hose) and a flow rate of up to 2.6 GPM (values claimed by the manufacturer). Thus, the Westinghouse WPX3400 achieves a cleaning power of 8840 Cleaning Units.
Initiating the engine of this gas pressure washer is achieved through a classic pull-start process.
Gasoline is stored in a fuel tank with a maximum capacity of 0.9 gallon.
Design & Handling
With its hand truck design and approximate dimensions of D21 x W19.5 x H39 in, the Westinghouse WPX3400 provides great mobility. Built to endure, the steel tubing frame ensures the assembly's longevity by providing stability and safeguarding internal components under all working conditions. The foam-padded fixed handle adds to the WPX3400 convenience of transport, while offering a comfortable grip.
At 63 lbs, this unit strikes a balance between portability and stability, making it easy for most users to handle. A significant portion of this weight is attributed to the inclusion of the 212cc engine and a sturdy steel tubing frame. Still, the WPX3400's two 12" never-flat wheels ensure easy handling and maneuverability.
Main Features
The Westinghouse WPX3400 comes with a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: A safe detergent storage is facilitated by a removable 0.5 gal tank. The Westinghouse WPX3400 is equipped with an automatic soap dilution mechanism, efficiently blending detergent to the predefined ratio of 12:1. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
- Pressure hose: The unit comes equipped with an included 25 ft ⌀5/16" high-pressure hose, which can be neatly stored on the unit when idle, thanks to a set of convenient hooks, ensuring easy access and organization.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: The table below shows you the 5 included nozzles and the surfaces they're the most appropriate for.
