Spray Tip Selection
Selecting Tip Size
Spray tips come in a variety of hole sizes for
spraying a range of fluids. Your sprayer
includes a tip for use in most paint spraying
applications. Use coatings tables on page 20
to determine the range of recommended tip
hole sizes for each fluid type.
Hints:
•
As you spray, the tip wears and
enlarges. Starting with a tip hole size
smaller than the maximum will allow
you to spray within the rated flow
capacity of the sprayer.
•
Use larger tip hole sizes with thicker
coatings and smaller tip hole sizes with
thinner coatings.
•
Tips wear with use and need periodic
replacement.
•
Tip hole size controls flow rate - the
amount of paint that comes out of the
gun.
Fan Width
Fan width is the size of the spray pattern,
which determines the area covered with each
stroke.
Hints:
•
Select a fan width best suited to the
surface being sprayed.
•
Wider fans allow provide better cover-
age on broad, open surfaces.
•
Narrower fans provide better control on
small, confined surfaces.
Understanding Tip Number
The last three digits of tip number (i.e.:
221413) contain information about hole size
and fan width on surface when gun is held 12
in. (30.5 cm) from surface being sprayed.
First digit when doubled
= approximate
fan width.
413 tip has
8-10 in. (20-25 cm)
fan width.
413 tip has
a 0.013 in.
hole size
Last two digits = tip hole size in thousands of an inch.
