CHECK SPRAY PATTERN

Start air-spraying (without electrostatics)
1. Start up with material supply set to approx. 0.05 to 0.15 MPa; 0.5 to 1.5 bar; 7 to 22 psi operating pressure.
2. Spray (pull trigger) and check the atomisation.
3. Set the fl uid pressure on the material supply to the point where a further increase in fl uid pressure would
signifi cantly improve fl uid atomization.
4. Open air pressure regulator for the atomizer air and adjust so as to achieve optimal atomization.
5. The width of the spray jet can be adjusted using the air adjustment (16) (only for fl at-jet method).
Note
The paint output volume can be changed by:
•
Changing the material pressure or
•
using a different fl at jet nozzle (see Chapter 9).
•
Reduction of the material valve stroke.
Infl uence of the air adjustment on the spray pattern shape
The spray pattern can be adjusted to suit the object being sprayed using the air adjustment. The illustration
below shows the infl uence of the shaping air regulator on the spraying pattern.
Other nozzle sizes can be used to obtain larger or smaller spraying patterns.
