The coating substances approved by the manufacturer of the coating substance for
spraying may be used; however, Krautzberger GmbH offers special designs for

Basic design, mode of operation
The design of the airless spray gun type KS as well as typical equipment features and
accessories are shown is the diagrams 140-0059, 140-0060, 140-0128 and 140-0064. A
pump supplies the material at a pressure of max. 35 MPa (350 bar) for the versions KS-
1, KS-1L, KS-1M and KS-2 or max. 25 MPa (250 bar) for the version KS-1D and KS-2D
(400bar for the KS-1D with stainless-steel head section) through a sufficiently pressure-
resistant hose to the material connection (27). Pulling the trigger (22 or 25) towards the
handle of the main element (12) pushes the valve needle (16) or the needle
reinforcement backwards against the pull-back pressure of the valve spring (19). The
sealing ball of the valve needle or needle reinforcement lifts from the valve seat of the
valve seat screw (4), thus releasing the material flow to the material nozzle (102), from
which the material is sprayed in the form of an elliptical cone jet. The volume of material
discharged depends solely on the nozzle size and the material pressure.
(!) Warning note!
In the risk or the event of an accident, the spray jet can be shut down quickly by
releasing the trigger (22 or 25).
The airless spray gun type KS is supplied in aluminium as standard; the parts coming
into contact with the material are available in stainless steel on request.

(i) Notes
The version KS-1D is equipped with material ducts with enlarged cross-section. Highly
viscous materials can be processed using appropriate material nozzles. During lengthy
use, fatigue is alleviated by the favourable power transmission (version KS-1L) or the
shift in the centre of gravity towards the handle ((i.e. towards the back) in the version KS-
1M).
