Description
Zoom on the Generac 7901
In a nutshell, the Generac 7901 is a heavy duty, commercial pressure washer, which not only offers an all-around versatile cleaning experience, but that also allows:
- spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- utilizing cleaning solutions, and rinsing surfaces clean
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
Its axial cam pump, which utilizes a 196cc engine, may deliver a pressure of up to 3100 PSI (almost 52 times more than a standard garden hose) and a flow of up to 2.4 GPM. Corresponding to these values is a cleaning power of 7440 Cleaning Units.
Initiating the Generac engine of this gas pressure washer is achieved through a classic pull-start process.
Fuel for the pressure washer is housed in a tank capable of holding up to 0.8 gallon of gasoline..
Design & Handling
Thanks to its hand truck design and approximate dimensions of D24.4 x W18.9 x H35.5 in, the Generac 7901 offers great mobility. Guaranteeing longevity, the robust steel frame offers stability and protects internal components, even when subjected to demanding tasks. The rubber-padded fixed handle adds to the 7901 convenience of transport, while offering a comfortable grip.
Weighing 57 lbs, this unit offers a manageable weight that allows for easy handling by most individuals. The unit's weight is principally a result of the inclusion of the 196cc Generac engine and a strong steel frame. However, with its two 10" never-flat wheels, the 7901 remains highly maneuverable.
Main Features
Along with the Generac 7901 itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: The pressure washer features a 0.5 gal tank for detergent storage. However, since the Generac 7901 does not feature a soap dilution mechanism, you'll have to make sure your detergent is correctly diluted before use. Attachment of a soap nozzle prompts the pressure washer to automatically introduce and blend the detergent with the water.
- Pressure hose: Utilizing a set of convenient hooks, the unit offers a convenient solution for storing the included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) when it's not in use, keeping it neatly organized.
- Spray gun and wand: A side hook allows for an easy storage of the included PowerDial spray gun and its wand.
- Nozzles: Review the table below to learn about the 4 included nozzles and the surfaces they're recommended for.
