Power
With an impressive 212cc engine powering it, the axial cam pump of this unit is capable of achieving a pressure of 3400 PSI (approximately 57 times greater than that of a standard garden hose) and a flow rate of up to 2.6 GPM (values claimed by the manufacturer). Corresponding to these values is a cleaning power of 8840 Cleaning Units.
The engine of this gas-powered pressure washer is initiated by a classic pull-start mechanism.
Containing gasoline, the pressure washer's fuel tank can hold a maximum of 0.9 gallon.
Design & Handling
Enhanced mobility is a key feature of the Westinghouse WPX3400, thanks to its hand truck design. 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.
With its 63 lbs weight, this unit offers a manageable size that allows for easy handling by most individuals, enhancing user convenience during operation. The unit's weight is principally a result of the inclusion of the 212cc engine and a strong steel tubing frame. However, with its two 12" never-flat wheels, the WPX3400 remains highly maneuverable.
Main Features
The Westinghouse WPX3400'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 storage is ensured by a removable 0.5 gal tank. The detergent is diluted with a 12:1 ratio by the Westinghouse WPX3400's automatic soap dilution mechanism. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
- Pressure hose: With a set of convenient hooks, the unit provides a convenient way to store the included 25 ft ⌀5/16" high-pressure hose when not in use, keeping it organized and readily accessible.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: Refer to the table below for details on the 5 included nozzles and their recommended surface applications.
