Choosing The Correct Tip; Uni-Tip Selection Chart - Graco A Series Manual

Choosing the Correct Tip

Consider the coating and the surface to be sprayed.
Make sure you use the best tip hole size for that coating
and the best fan width for that surface.
Tip Hole Size
Tip hole size controls the flow rate (the amount of paint
that comes out of the gun).
Hints:
• Generally, use larger tip holes sizes with thicker
coatings and smaller tip hole sizes with thinner coat-
ings
• The maximum tip hole size that a sprayer can sup-
port is related to its maximum flow rate. The maxi-
mum tip hole size supported by the ESP sprayer is
0.015 in (0.38 mm).
• Tips wear with use and need periodic replacement.
Fan Width
Fan width is the size of the spray pattern, which deter-
mines the area covered with each stroke. For a given tip
hole size, narrower fans deliver a thicker coat and wider
fans deliver a thinner coat.
Hints:
• Select a fan width best suited for the surface being
sprayed.
• Wider fans provide better coverage on broad, open
surfaces.
• Narrower fans provide better control on small, con-
fined surfaces.

Understanding the Tip Number
The last three digits of tip number (example: 69-413)
contain information about hole size and fan width on the
surface when gun is held 30 cm (12 in.) from surface
being sprayed.
First digit when doubled =
approximate fan width.
413 tip has a
0.013 in. hole size
Last two digits = tip hole size in
thousands of an inch
