Selecting the Right Tip
Tip Hole Size
• Spray should be atomized (evenly distrib-
uted, no gaps or edges). Start at a low
pressure setting, increase pressure a little
at a time until paint atomizes.
• Fluid flow rate is controlled by tip hole size.
• The best tip hole size for fluid you are
spraying is determined by type of coating
and type of surface you are spraying.
• Use large tip hole size when spraying
thicker coatings.
• Use small tip hole size when spraying thin-
ner coatings.
• Tips wear and enlarge when you spray.
Starting with a tip hole size smaller than the
maximum will allow you to spray within
rated flow capacity. To prevent excessive
wear, spray at lowest pressure that atom-
izes paint.
NOTE: If maximum pressure of sprayer is not
enough for good spray pattern, tip is too large or
worn. See Reversible Tip Selection Table, page
16.
Fan Width
Fan Width is the size of the spray pattern.
Narrow Fan
• Thicker coat
• Better control
• Small, confined surfaces
Wide Fan
• Thin coat
• Fast coverage
• Broad, open surfaces
