Trailer-Mounted High-Pressure Washers

The Universal 22HP 500-50/150P is made for the jobs that sit between a portable washer and a large jetting trailer. It carries its own 500 L water supply, a self-priming positive-displacement plunger pump and the hose handling needed to arrive, set up and begin work with less site infrastructure.

Compact by design

A UV-stabilised, corrosion-resistant polyethylene tank sits inside a heavy-duty steel protective frame. Two braked manual hose reels, a 30 m high-pressure hose and 500 mm lance keep the working equipment organised and immediately accessible.

Pressure with independence

The Honda petrol engine frees the unit from an electrical supply, while the fully adjustable regulator lets the operator set pressure for the application. An inline high-volume filter helps protect the pump, and the single-axle roadworthy chassis makes the complete system easy to position across changing work sites.

Built here. Useful anywhere.

Designed and assembled in South Africa for regular work in demanding environments, the Universal is a deliberately serviceable field unit. Werner can configure hose lengths, reels, nozzle sets and skid or stationary alternatives around the customer’s actual cleaning requirement.
