The Fitjet nozzle uses the principle of the straight jet in order to increase the impact force while the pressure is reduced.
By this way the support damages is avoided and the rotating jet covers a surface almost equal to the flat jet surface.
Because of this principle, the impact force of the Fitjet nozzle is higher than the impact force of the high pressure flat jet (see table impact force link above)
Working and use of the Fitjet nozzle
WORKING CONCEPT OF THE FITJET
The cleaning quality depends on the pump pressure and flow rate. These two parameters (pressure and flow rate) define the impact force on the surface to clean. This impact force varies if the adjustment of pump pressure is changed or if we use a different pump with a lower pressure and a bigger flow rate.
With the use of high pressure, there is a phenomenon of abrasion with a support attack.
Also, the impact force depends on the praying angle of the nozzle used; wider the angle is more the impact force decreases.
- Example: A nozzle with a flat jet angle of 15° allows only 30% of the impact force by cm2 compared to a straight jet (see table below).
Medium pressure rotating nozzle working at 10 to 50 bars.
