TEST OF SPRAY PATTERN

Start AirCoat spraying (without electrostatics)
1. Start up with product supply set to approx. 8 MPa; 80 bar; 1,160 psi operating pressure.
2. Spray (release locking device and pull trigger) and at the same time, check the
atomization.
3. Set the product pressure on the product supply to the point where a good product
atomization is achieved.
4. Open the air pressure regulator for the atomizing air and adjust it so that an optimal
atomization is achieved. (The interrelation between spray pattern and atomizing air
is shown in the fi gure below).
5. With the air adjustment on the gun, set the ratio shaping air / atomizing air so as to
achieve an optimum spray pattern.
Note:
Repeat points 4 and 5 until the optimum spray pattern is reached (iterative process).
Spray pattern shapes
No atomization air
Notice
The paint output can be changed by:
changing the product pressure or
using a diff erent fl at jet nozzle (see Chapter 12.2).
Infl uence of the air adjustment on the spray pattern shape
The spray pattern can be adjusted to suit the object to be sprayed using the air adjustment.
The illustration 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.
