bubbles disturb when spraying and can, in fact, lead
to interruption of operation.

Airless process

The main areas of application are thick layers of highly viscous
coating material for large areas and a high consumption of material.
A piston pump takes in the coating material by suction and conveys it
pressure has the e ect of micro ne atomisation of the coating
material.
As no air is used in this process, it is described as an AIRLESS process.
This method of spraying has the advantages of nest atomisation,
cloudless operation and a smooth, bubble-free surface. As well as
these, the advantages of the speed of work and convenience must
be mentioned.

Functioning of the unit

In the following there is a short description of the technical
construction for better understanding of the function.
units.
A gear unit transfers the driving force to a crankshaft. The crankshaft
moves the pistons of the material feed pump up and down.
The inlet valve is opened automatically by the upwards movement
of the piston. The outlet valve is opened when the piston moves
downward.
The coating material ows under high pressure through the high-
the tip it atomizes.
The pressure regulator controls the volume and the operating
pressure of the coating material.
