Description

Zoom on the Pressure-Pro PP4440K

The Pressure-Pro PP4440K, a heavy duty, commercial pressure washer, gives its user an all-around versatile cleaning experience, topped off by the following features:

  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and frail surfaces
  • application of detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

The Pressure-Pro PP4440K in use

The Pressure-Pro PP4440K

Its triplex pump, which utilizes an impressive 429 cc engine, may deliver a pressure of up to 4400 PSI (almost 73 times more than a standard garden hose) and a flow of up to 4 GPM. These values correspond to a cleaning power of 17600 Cleaning Units.

The KOHLER CH440K engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

Gasoline is stored in a steel fuel tank with a maximum capacity of 1.9 gallon.

Design & Handling

The Pressure-Pro PP4440K offers superb mobility, with a hand truck design and approximate dimensions of D26.5 x W22.5 x H40.2 in. The strong steel frame assures assembly longevity. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

With a weight of 121 lbs, the model is not lightweight. Therefore, it may be challenging to manually carry it around and transport it. The main contributors to its weight are its 429 cc KOHLER CH440K engine, the triplex pump and steel frame. However, its two 10" never-flat wheels play an important part in its maneuverability, as they allow for a smooth manipulation on the job.

Main Features

Along with the Pressure-Pro PP4440K 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 is fed in through a siphon hose, since the device lacks a soap tank. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: Using a set of convenient hooks, the included 50 ft ⌀3/8" high-pressure hose can be easily stored on the unit when it is not running.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 4 included nozzles, along with the surfaces which they are the most suitable for.

  • Safety: Safety of operation is enhanced by a low oil protection and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Pressure-Pro PP4440K comes with soap hose, pressure hose, wand, spray gun and oil.
  • Emissions: The Pressure-Pro PP4440K is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.
