Zoom on the Pressure-Pro PP4240H
In summary, the Pressure-Pro PP4240H is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- thorough cleaning of hard, paint-free surfaces
- cleaning of painted or delicate surfaces
- application of detergent and cleaning solutions
With an impressive 389 cc (13 hp) engine, its triplex pump delivers a pressure of 4200 PSI (roughly 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer), resulting in the Pressure-Pro PP4240H's cleaning power of 16800 Cleaning Units.
A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Honda GX390 engine.
Gasoline is stored in a steel fuel tank with a maximum capacity of 0.3 gallon.
Design & Handling
With its hand truck design and approximate dimensions of D26.5 x W22.5 x H40.2 in, the Pressure-Pro PP4240H provides great mobility. The robust and sturdy steel frame offers longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
With a weight of 115 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. Its 389 cc Honda GX390 engine, the triplex pump and steel frame are mainly responsible for its heavy weight. However, its two 10" never-flat wheels play an important part in its maneuvrability, as they allow for a smooth manipulation on the job.
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: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is automatically added to the water when a soap nozzle is connected.
- Pressure hose: The 50 ft ⌀3/8" high-pressure hose, which is included with the device, can be stored neatly on the unit itself when idle, using a set of convenient hooks.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: The 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
