The DYNAJET Nozzle Guide: Shapes, Angles and Applications

Selecting the right nozzle is a key part of working efficiently with a DYNAJET high-pressure cleaner. The nozzle shape, jet angle and working pressure together determine how the water hits the surface, how fast the work progresses and how much control the operator has. For professional users, that means the difference between effective cleaning and unnecessary wear or surface damage.

DYNAJET nozzle ABC distinguishes between spot-jet nozzles, flat-jet nozzles and rotating nozzles. Spot-jet nozzles create a round, concentrated jet and are used for tasks that need high impact, such as cutting, spraying out small moulds or concrete repair. Rotating nozzles extend this principle by moving the jet over a wider area, which can improve coverage in demanding applications. Flat-jet nozzles spread the water into a wider pattern and are better suited to cleaning larger surfaces and working on rougher materials.

The right choice always depends on the task and the material. Simple cleaning, surface preparation and concrete removal place very different demands on the nozzle, so one solution does not fit every job. That is why DYNAJET offers a range of nozzles for different working conditions instead of a single universal option. In practice, users should also keep the distance to the surface under control, because nozzle performance changes with spacing.

Jet angle and working pressure must be considered together. A larger angle and lower pressure create a softer jet, while a smaller angle and higher pressure increase impact. This helps operators adapt the spray pattern to the application, whether the goal is careful cleaning, refurbishment or more aggressive removal work. Recoil force and suitable protective measures should also be part of nozzle selection, especially when working at high pressure or in ultra-high-pressure applications.
