BasicLINE: Spray gun: KS 5D (Airless)

The hand sprayer operates according to the Airless principle, i.e. the spray jet is generated exclusively by the material pressure that presses the material through a nozzle. After exiting from the nozzle, the spray jet takes on the shape specified by the nozzle. It is directed to the workpiece. The effective spraying jet is not as wide as theoretically possible.

The coating material to be processed shall be placed on the surface by a person passing the hand-held sprayer manually over the surface to be coated and triggering the spraying process at the specified point by pressing the trigger lever. The coating material is supplied to the hand sprayer in liquid form under high material pressure.

By pulling the trigger lever to the handle of the main body, the valve needle is pushed backwards against the reset force of the valve spring. The valve needle pushes itself out of the valve seat of the valve seat screw and thereby releases the material flow to the material nozzle. There, the material is sprayed as an elliptical cone beam.

The amount of material outlet depends exclusively on the nozzle size and the material pressure!

The size and shape of the beam can only be changed by changing the nozzle. The diameter of the nozzle bore determines the amount of material flow, size and geometry of the always elliptical shaped nozzle opening determine the height and width of the beam.

There is a large number of airless nozzles available. They can be obtained from Krautzberger GmbH. The nozzle can be continuously rotated 360° in the axis of the spray jet and locked in any position.

This allows the angle with which the beam hits the workpiece to be optimally adapted to the respective conditions. The use is particularly advantageous if comparatively large quantities of material per time unit are to be processed.
