Power
The ECHO PW-3100
With a powerful 212cc (7 hp) engine powering it, the axial cam pump of this unit are capable of achieving a pressure of 3100 PSI (approximately 52 times greater than that of a standard garden hose) and a flow rate of up to 2.5 GPM (values claimed by the manufacturer). Corresponding to these values is a cleaning power of 7750 Cleaning Units.
To initiate the Rato R225 engine of this gas-powered pressure washer, a traditional pull-start mechanism is employed.
Gasoline is stored in a fuel tank with a maximum capacity of 0.95 gallon.
Design & Handling
With its hand truck design, the ECHO PW-3100 provides excellent maneuverability. The robust steel frame guarantees longevity of the assembly, providing stability and protection for internal components, even under demanding working conditions. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing in at 77 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. The main contributors to its weight are its 212cc Rato R225 engine and steel frame. However, the incorporation of two 12" never-flat wheels makes navigating the PW-3100 less cumbersome, even on uneven terrain.
Main Features
Along with the ECHO PW-3100 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: Detergent storage is facilitated by the inclusion of a 0.92 gal tank. Once a soap nozzle is connected, the pressure washer automatically blends the detergent with the water flow.
- Pressure hose: Utilizing a set of convenient hooks, the unit offers a convenient solution for storing the included 25 ft ⌀3/8" high-pressure hose when it's not in use, keeping it neatly organized.
- Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
- Nozzles: In the table below, you can see the 4 included nozzles alongside their respective recommended surface uses.
