Airless Tip Selection
Tips are selected by the orifice size and fan width. The proper
selection is determined by the fan width required for a specific
job and by the orifice size that will supply the desired amount of
fluid and accomplish proper atomization.
For light viscosity fluids, smaller orifice tips generally are desired.
For heavier viscosity materials, larger orifice tips are preferred.
Please refer to the chart below.
i
Do not exceed the sprayer’s recommended tip
size.
The following chart indicates the most common sizes and the
appropriate materials to be sprayed.
Tip Size
Spray Material
Filter Type
.011 – .013 Lacquers and stains
100 mesh filter
.015 – .019 Oil and latex
60 mesh filter
.021 – .026 Heavy bodied latex and blockfillers
30 mesh filter
Fan widths measuring 8” to 12” (20 to 30 cm) are preferred
because they offer more control while spraying and are less likely
to plug.
Liquid Shield Plus
Cleans and protects spray systems against
rust, corrosion and premature wear. Now with
-25º anti-freeze protection.

13.1 Selection of tip
To achieve faultless and rational working, the selection of the tip is of the greatest importance.
In many cases the correct tip can only be determined by means of a spraying test.
Some rules for this:
The spray jet must be even.
If streaks appear in the spray jet the spraying pressure is either too low or the viscosity of the coating material to high.
Remedy
: Increase pressure or dilute coating material. Each pump conveys a certain quantity in proportion to the size of the tip:
The following principle is valid:
large tip =
low pressure
small tip =
high pressure
There is a large range of tips with various spraying angles.
13.2 Servicing and cleaning of Airless hard-metal tips
Standard tips
If a different tip type has been fitted, then clean it according to manufacturer’s instructions.
The tip has a bore processed with the greatest precision. Careful handling is necessary to achieve long durability. Do not forget the fact
that the hard-metal insert is brittle! Never throw the tip or handle with sharp metal objects.
The following points must be observed to keep the tip clean and ready for use:
1. Turn the relief valve handle fully counterclockwise (
k
Circulation).
2. Switch off the gasoline engine.
3. Dismount the tip from the spray gun.
4. Place tip in an appropriate cleaning agent until all coating material residue is dissolved.
5. If there is pressure air, blow out tip.
6. Remove any residue by means of a sharp wooden rod (toothpick).
7. Check the tip with the help of a magnifying glass and, if necessary, repeat points 4 to 6.
