Description
Zoom on the Predator 4400
In summary, the Predator 4400 is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- spot cleaning of hard, unpainted surfaces or high reach areas
- intense cleaning of tough, paintless surfaces
- cleaning of painted and frail surfaces
- use of detergent and cleaning solutions
Its power characteristics and design, its main features and all its additional features are presented ahead.
Power
The Predator 4400
Using a powerful 420 cc (13 hp) engine, its brass triplex pump delivers a pressure of up to 4400 PSI (roughly 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). Together, the values result in a cleaning power of 18480 Cleaning Units.
The Predator engine of this gas-powered pressure washer gets started by a classic pull-start mechanism.
Gasoline storage is facilitated by a fuel tank with a maximum capacity of 1.45 gallon, which provides an approximate runtime of 120 minutes.
Design & Handling
The wheelbarrow design of the Predator 4400 grants mobility and stability to the unit. Its sturdy welded steel frame provides longevity to the assembly. The handle adds to the 4400 convenience of transport.
This model weighs 133.5 lbs. For this reason, it cannot be called lightweight and thus, carrying and transporting it might be somewhat challenging. Its 420 cc Predator engine, the triplex pump and welded steel frame add up to a large chunk of the device's weight. However, the unit’s two 12" never-flat wheels are crucial to its maneuverability, since they provide a smooth method of manipulation on the job.
Main Features
The Predator 4400
The Predator 4400's package includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, with a more detailed description below.
- Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. When a soap nozzle is connected, the detergent will be added automatically to the water.
- Pressure hose: The included 50 ft high-pressure hose can be neatly stored on the unit when idle thanks to 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 5 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.
0° | 15° | 25° | 40° | Soap | |
