Description
Zoom on the Generac 7901
The Generac 7901 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:
- spot cleaning of hard, unpainted surfaces, reaching high areas, and removing stubborn stains
- gentle cleaning for sensitive surfaces, and wide coverage cleaning with low pressure
- applying detergents and cleaning agents, and rinsing off surfaces
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Generac 7901's axial cam pump, powered by a 196cc engine, can provide a pressure of up to 3100 PSI (approximately 52 times more than a standard garden hose) and a flow of up to 2.4 GPM (values claimed by the manufacturer). Thus, the Generac 7901 achieves a cleaning power of 7440 Cleaning Units.
To initiate the Generac engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
The pressure washer's tank has a maximum capacity of 0.8 gallon for storing gasoline.
Design & Handling
The hand truck design of the Generac 7901 ensures effortless movement and transportation. The robust steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The rubber-padded fixed handle adds to the 7901 convenience of transport, while offering a comfortable grip.
With a weight of 57 lbs, this unit is designed for ease of maneuverability, catering to a wide range of users. This substantial weight can be partially attributed to the incorporation of the 196cc Generac engine and a resilient steel frame. Yet, its two 10" never-flat wheels ensure the 7901 remains effortlessly 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: A safe detergent storage is facilitated by a 0.5 gal tank. Because the Generac 7901 lacks a soap dilution function, it's important to dilute detergent appropriately before using the pressure washer. Upon connecting a soap nozzle, the pressure washer takes over the task of seamlessly combining the detergent with the water flow.
- Pressure hose: The included 25 ft ⌀1/4" high-pressure hose (3100 PSI rating) can be neatly stored on the unit when not in use, utilizing a set of convenient hooks for convenient organization.
- Spray gun and wand: A side hook allows for an easy storage of the included PowerDial spray gun and its wand.
- Nozzles: The following table provides information on the 4 included nozzles and their recommended surface uses.
0° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||
| Fencing, deck, patio | ||||
| Lawn equipment, boat, RV |
Please be aware: The shapes of the depicted nozzles are for illustration purposes and may differ. Symbols utilized include a indicating 'Not recommended,' a for 'Suitable,' and an for 'Use with caution.'
Other Features
- PowerDial™ gun: The PowerDial™ ergonomic spray gun features 4 different power modes, which can be selected simply, according to your cleaning task – soap, wood, concrete or car.
- Onboard storage: The Generac 7901 features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
- Pressure control: Water pressure can be manually changed, using the adjustable throttle of the trigger gun.
- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage) and a trigger lock mechanism (which prevents accidental operation).
- Accessories: Included with the Generac 7901 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as spray gun, wand, pressure hose, funnel and oil.
