Adjusting the spray pattern

Air and fluid nozzles are available in various sizes. There are 4 different families:
n Round jet – cone-shaped jet in front of the nozzle.
n Flat jet – width-adjustable jet for flat-shaped application.
Rotary stream – a rotary pulse produces a highly "swirled" spray jet; for difficult workpiece
n
geometries (angular sections etc.).
n Full-cone rotary stream – a rotary pulse produces a highly "swirled" spray jet; for difficult
workpiece geometries (back cuts, etc.).
Adjust the spray pattern with the following measures:
n Change the atomiser air pressure.
n Change the pressure of the spray fluid.
n Select another nozzle size.
n Adjusting the needle stroke (
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.
