Zoom on the Simpson PS4240
The Simpson PS4240 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- focused spot cleaning on hard, unpainted surfaces, accessing high spots, and efficiently eliminating stubborn stains
- broad cleaning of hard surfaces, vehicle washing, and surface preparation for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergent and cleaning solutions, and rinsing surfaces
The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.
Power
The Simpson PS4240's triplex pump, powered by a powerful 389cc (11.7 hp) engine, can provide a pressure of up to 4200 PSI (approximately 70 times more than a standard garden hose) and a flow of up to 4 GPM (CETA-certified values). Thus, the Simpson PS4240 achieves a cleaning power of 16800 Cleaning Units.
The Honda GX390 engine of this gas pressure washer is activated by pulling a starter cord, following a traditional approach.
The pressure washer's steel tank has a maximum capacity of 1.6 gallon for storing gasoline..
Design & Handling
Designed with a wheelbarrow configuration, the Simpson PS4240 ensures improved mobility and stability, allowing for effortless movement and reliable operation on challenging surfaces. Guaranteeing longevity, the robust welded steel frame offers stability and protects internal components, even when subjected to demanding tasks. The handle adds to the PS4240 convenience of transport.
With its weight clocking in at 136 lbs, this unit's heftiness can't be ignored, presenting significant difficulties for users who need to lift and transport it, especially over uneven terrain. The main contributors to its weight are its 389cc Honda GX390 engine, the triplex pump and welded steel frame. However, the incorporation of two 13" pneumatic wheels makes navigating the PS4240 less cumbersome, even on uneven terrain.
Main Features
Along with the Simpson PS4240 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: While not equipped with a soap tank, the device maintains detergent supply through a siphon hose. Connection of a soap nozzle triggers the pressure washer to automatically incorporate the detergent into the water stream.
- Pressure hose: When not in use, the unit allows for tidy storage of the included 50 ft ⌀3/8" high-pressure hose using a set of convenient hooks, ensuring convenient organization.
- Spray gun and wand: Both the classic ergonomic spray gun and its steel wand may be conveniently stored in a side hook.
