Selecting Tip Hole Size

Tips come in a variety of hole sizes for spraying a	• Maximum tip hole sizes supported by the
range of fluids. Your sprayer includes an 0.015 in	sprayer:
(0.38 mm) tip for use in most spraying applications.	– X5: 0.015 in. (0.38 mm)
Use the following table to determine the range of
	– X7: 0.017 in. (0.43 mm)
recommended tip hole sizes for each fluid type. If
	– ProX7: 0.017 in. (0.43 mm)
you need a tip other than the one supplied, see the
	– ProX9: 0.019 in. (0.48 mm)
Reversible Tip Selection Chart on page 16.

HINTS:

•As you spray, the tip wears and enlarges. Start- ing with a tip hole size smaller than the maxi- mum will allow you to spray within the rated flow capacity of the sprayer.

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:

–X5: 0.015 in. (0.38 mm)

–X7: 0.017 in. (0.43 mm)

–ProX7: 0.017 in. (0.43 mm)

–ProX9: 0.019 in. (0.48 mm)

Fan Width

Fan width is the size of the spray pattern, which determines the area covered with each stroke. Nar- rower 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.

•Tips wear with use and need periodic replace- ment.
