Tip Selection
Selecting Tip Hole Size
Tips come in a variety of hole sizes for spraying a
range of fluids. Your sprayer includes an 0.017 in
(0.43 mm) tip or maybe 0.019
”
(0.48mm) for use
in most spraying applications.
Use the following
table to determine the range of recommended tip
hole sizes for each fluid type. If you need a tip
other than the one supplied, see the
Reversible
Tip Selection Chart
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.
•
Maximum tip hole sizes supported by the
sprayer:
–
DP6825 : 0.021 inch .
–
DP6830 : 0.025 inch .
–
DP6835 : 0.029 inch( one gun)
0.017 inch( two guns)
Choosing the Correct Tip
Consider coating and surface to be sprayed.
Make sure you use best tip hole size for that
coating and best fan width for that surface.
Tip Hole Size
Tip hole size controls flow rate - the amount of
paint that comes out of the gun.
HINTS :
•
Use larger tip hole sizes with thicker coatings
and smaller tip hole sizes with thinner coatings.
•
Maximum tip hole sizes supported by sprayer:
–
DP6825 : 0.021 inch .
–
DP6830 : 0.025 inch .
–
DP6835 : 0.029 inch( one gun)
0.017 inch( two guns)
•
Tips wear with use and need periodic
replacement.
Fan Width
Fan width is the size of the spray pattern, which
determines the area covered with each stroke.
Narrower fans deliver a thicker coat, and wider
fans deliver a thinner coat.
HINTS:
•
Select a fan width best suited to the surface
being sprayed.
•
Wider fans allow provide better coverage on
broad, open surfaces.
•
Narrower fans provide better control on small,
confined surfaces.
