* Measured with water
This is the force acting on the gun and transmitted to the hand guiding the gun. Values for higher spraying
pressures can be calculated proportionally.
Caution: An additional turning moment may be caused when using pole guns.

Spray tip selection

Selection of the correct tip is essential for correct and efficient spraying. In many cases, the right tip can be
determined only by conducting a spray test.
Here are a few rules:
The spray fan must be uniform.
If streaks appear in the spray fan, the spraying pressure is too low or the viscosity of the material is too high.
Remedy: Increase pressure or thin the material. Each pump delivers a specific volume directly proportional
to the size of the tip:
Rule of thumb: large tip
small tip
A very wide range of tips is available with widely ranging spaying angles.
