Description
Zoom on the Pressure-Pro PP4240H
In summary, the Pressure-Pro PP4240H is a commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- general cleaning of hard surfaces , washing vehicles, and preparing surfaces for painting
- gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
- using cleaning solutions, and rinsing surfaces to remove residue
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
Fueled by an impressive 389cc (13 hp) engine, its triplex pump can generate a forceful pressure of 4200 PSI (roughly 70 times that of a standard garden hose) and a flow rate of up to 4 GPM (values claimed by the manufacturer). When these values are taken together, they yield a cleaning power of 16800 Cleaning Units.
To start the Honda GX390 engine of this gas-powered washer, users employ the familiar pull-start technique.
Gasoline is stored in a steel fuel tank with a maximum capacity of 0.3 gallon.
Design & Handling
With its hand truck design, the Pressure-Pro PP4240H provides excellent maneuverability. The sturdy steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
With its weight clocking in at 115 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. Its 389cc Honda GX390 engine, the triplex pump and steel frame are mainly responsible for its heavy weight. However, the incorporation of two 10" never-flat wheels makes navigating the PP4240H less cumbersome, even on uneven terrain.
Main Features
The Pressure-Pro PP4240H comes with a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are detailed below.
- Soap injection: Despite the absence of a soap tank, detergent supply is facilitated through the use of a siphon hose. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with the water flow.
- Pressure hose: For easy organization, the included 50 ft ⌀3/8" high-pressure hose can be stored on the unit using a set of convenient hooks when it's not in use, ensuring a clutter-free workspace.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.
