Description

The Predator® Commercial Duty Pressure Washer delivers 4400 PSI and 4.2 GPM for unbeatable cleaning power. The professional-grade Annovi Reverberi™ triplex pump has ceramic coated pistons for exceptionally long performance life.

Zoom on the Predator 4400

In a nutshell, the Predator 4400 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 and high-reach cleaning
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and fragile surfaces
  • applying detergent and cleaning solutions

The following sections will present you in detail its power characteristics and design, its main features and all the additional features it has to offer.

Power

The Predator 4400 in use

The Predator 4400

Powered by a powerful 420 cc (13 hp) engine, its brass triplex pump can deliver a pressure of 4400 PSI (around 73 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer). Combined, these values mean that the Predator 4400 has a cleaning power of 18480 Cleaning Units.

A classic pull-start mechanism is responsible for starting the gas-powered pressure washer’s Predator engine.

A fuel tank with a maximum capacity of 1.45 gallon is used to store gasoline, which provides an approximate runtime of 120 minutes.

Design & Handling

The wheelbarrow design of the Predator 4400 grants mobility and stability to the unit. The robust and sturdy welded steel frame offers longevity to the assembly. The handle adds to the 4400 convenience of transport.

The unit's weight of 133.5 lbs renders its carrying and transportation challenging, as it is far from lightweight. 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 maneuvrability, since they provide a smooth method of manipulation on the job.

Main Features

The Predator 4400

Along with the Predator 4400 itself, the package also includes a spray gun, a wand, a pressure hose, 5 nozzles and a detergent injection feature, which are discussed in further detail below.

  • Soap injection: Detergent is fed in through a siphon hose, since the device lacks a soap tank. If a soap nozzle is attached, the device will proceed to add the detergent to the water automatically.
  • 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: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
  • 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.
