Technical Description

PILOT III F-HD: Manual spray gun for conventional atomisation
Model versions: • with gravity-feed cup
• with syphon-feed cup
• with material connection
PILOT III F-MD: Manual spray gun for medium pressure
Model versions: • with gravity-feed cup
• with material connection.
The spraying pressure is 1.2 to 1.4 bar with an input pressure of 3.0 to 3.3 bar.
PILOT III K: Manual spray gun for adhesives
Model versions: • with gravity-feed cup
• with material connection.
The material flow rate is dependent on the diameter of the nozzle and the adjustment
of the material pressure at the pressure tank or material pressure regulator. In additi-
on, the material flow rate can be controlled by screwing the adjusting screw in or out.
For further adjustment possibilities, see Section 6. Changing the Spray Pattern.
Changing the material input of the spray gun
The PILOT III F gun body allows for the possibility to change the material input
according to user needs. These changes can be performed within seconds.

In case the operation must be reversed and a gra-
vity-feed cup is to be installed, the steps must be
taken accordingly. Medium-pressure guns, HVLP
guns and spray guns for use with adhesives may
not be equipped with a syphon-feed cup.
