Tip Selection
Selecting Tip Hole Size
Tips come in a variety of hole sizes for spraying a range
of fluids. Your sprayer includes an 0.015 in (0.38 mm)
tip for use in most spraying applications. Use the follow-
ing 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
Tip Selection Chart
below.
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:
– Project Painter Models: 0.015 in. (0.38 mm)
– 150 Models: 0.015 in. (0.38 mm)
– 170 Models: 0.017 in. (0.43 mm)
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.
•
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. 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, con-
fined surfaces.
Understanding Tip Number
The last three digits of tip number (i.e.: 286413) contain
information about hole size and fan width on surface
when gun is held 12 in. (30.5 cm) from surface being
sprayed.
