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.
