SPRAYING TECHNIQUE

AirCoat
In the AirCoat technique, the materials is pressed through the
nozzle at a relatively low pressure where air is added, practi-
cally surrounding it like a sleeve.
The very ne atomization makes this technique particularly
suitable for top-quality paint work.
Airless
As no air is used in this process, it is described as an AIRLESS
process.
This method of spraying has the advantages of nest atomi-
sation, cloudless operation (depending of a correct unit ad-
justment) and a smooth, bubblefree surface. As well as these,
the advantages of the speed of work and convenience must
be mentioned. The main area of application are thick layers of
highly viscous coating material.

FUNCTIONING OF THE UNIT

The following section contains a brief description of the techni-
cal construction for better understanding of the function:
SuperFinish 17ex is a pneumatically driven high-pressure paint
spraying equipment.
The compressed air drives the hydraulic pump via a coupling (1).
A piston (2) is moved up and down so that hydraulic oil is moved
under the diaphragm (3) which then moves.
In detail:
The downwards movement of the machine opens the disk inlet
valve (4) automatically and coating material is sucked in.
During the upwards movement of the diaphragm, the coating
material is displaced and the outlet valve opens while the inlet
valve is closed.
The coating material ows under high pressure through the
high-pressure hose to the spray gun and is atomized when it
exists from the tip.
The pressure control valve limits the pressure of the coating ma-
terial.
A pressure change when the same tip is used also leads to a
change in the amount of paint atomized.
