n Round jet – cone-shaped jet in front of the nozzle.
n Flat jet – width-adjustable jet for flat-shaped application. Depending on the design, flat jet
nozzles can be adjusted to adapt to the work piece geometry either seamlessly or in 45°
increments.
n Rotary jet – a rotary pulse produces a highly "swirled" spray jet; for difficult work piece geo-
metries (angular sections etc.).
n Full-cone rotary jet – a rotary pulse produces a highly "swirled" spray jet; for difficult work
piece geometries (back cuts, etc.).
The spray pattern can be adjusted with the following measures:
n Change the atomiser air pressure.
Change the pressure of the spray fluid.
n
Select another nozzle size.
n
Adjust the needle stroke (optional) (
n
setting' on page 26).
Too-high air pressure causes unnecessarily high air consumption and too-strong atomisation
of the spray fluid. It is recommended that you first adjust the spray pattern by varying the air
and spray fluid pressure. If you cannot achieve satisfactory results this way, you should
experiment with other nozzle sizes.
To reduce overspray and the concentration of harmful substances when coating, observe the fol-
lowing points:
Guide the spray jet vertically to the surface
n
Adjust the spray jet to suit the geometry of the work piece
n
The spray gun should be as close to the work piece as possible
n
Always spray in the extraction direction
