1.1

Function

The hand-held spray gun, type KS 5, is used to coat surfaces such as metal, plastic, ceramics,
wood and similar materials as well as other suitable surfaces. Typical coating materials include
paints, dyes, water-soluble paints, adhesives, oils, and anti-adhesives.
The hand-held spray gun operates based on the airless principle, which means the spray jet is
exclusively generated by the material pressure, which presses the material through a nozzle. After
exiting the nozzle, the spray jet takes the shape specified by the nozzle. It is directed towards the
work piece. The effective spray jet is not quite as wide as theoretically possible.
The coating material that is to be processed is applied to the surface by a person who is manually
guiding the hand-held spray gun over the surface that needs to be coated and who is starting the
spraying process at the respectively intended location by operating the trigger. The coating mate-
rial is fed to the hand-held spray gun in liquid form under high material pressure.
Pulling the pull lever towards the handle of the main element moves the valve needle back against
the resetting force of the valve spring. The valve needle slides out of the valve seat of the valve
seat screw and thereby releases the material flow to the fluid nozzle. It sprays the material as an
elliptical cone jet.
The volume of the exiting material depends exclusively on the nozzle size and the material pres-
sure!
The volume and shape of the jet can only be modified by changing the nozzle. The diameter of the
nozzle bore determines the material flow volume, while the size and geometry of the always ellipti-
cally shaped nozzle opening determine the height and width of the jet.
A large number of airless nozzles are available. They can only be purchased from Krautzberger
GmbH.
The nozzle can be seamlessly turned in the axis of the spray jet by 360° and locked into place in
any position. This allows an optimal adjustment of the angle with which the jet hits the work piece
to the respective conditions.
The KS model is particularly suitable for use where comparatively large volumes of material need
to be processed per unit of time.
