Description

Zoom on the Pressure-Pro PP4440K

In summary, the Pressure-Pro PP4440K is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:

  • thorough cleaning of hard, paint-free surfaces
  • cleaning of painted and fragile 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

The Pressure-Pro PP4440K's triplex pump, powered by a powerful 429 cc engine, can provide a pressure of up to 4400 PSI (approximately 73 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). The Pressure-Pro PP4440K thus has a cleaning power of 17600 Cleaning Units.

This gas-powered pressure washer’s KOHLER CH440K engine is started by a traditional pull-start mechanism.

A steel fuel tank with a maximum capacity of 1.9 gallon is used to store gasoline.

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. Its sturdy steel frame provides longevity to the assembly. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.

At 121 lbs, we can't really say that the unit is a lightweight, and manually lifting or transporting it could be a challenge. The major reasons for its heavy weight are its 429 cc KOHLER CH440K engine, the triplex pump and steel frame. However, the unit’s two 10" never-flat wheels are crucial to its maneuvrability, since they provide a smooth method of manipulation on the job.

Main Features

The Pressure-Pro PP4440K's package includes a spray gun, a wand, a pressure hose, 4 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. Whenever a soap nozzle is connected, the detergent is automatically added to the water.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by 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 4 nozzles included with the device, and the respective surfaces which they’re the most suitable for, are shown in the following table.

Other Features

  • Onboard storage: Stay prepared for any job with Pressure-Pro PP4440K's handy storage area, which allows you to neatly store any nozzles and accessories which you may need for the job.
  • Safety: Safety of operation is enhanced by a low oil protection and a trigger lock mechanism (which prevents accidental operation).
  • Accessories: On top of an owner's manual (opens in a new tab) and the usual documentation to get you swiftly started, the Pressure-Pro PP4440K also comes with pressure hose, spray gun, wand, oil and soap hose.
  • Emissions: The Pressure-Pro PP4440K is EPA-approved and CARB-compliant. This means that this pressure washer can be bought and sold in each of the 50 states, including California.
