The biggest problem with airless spray tips is that they wear out! When you combine high pressure, high flow and abrasive materials something has to give.
When the fan has lost 25% of its original size, it is time to replace the tip. In this instance as the orifice of the tip wears, the spray pattern changes, deteriorating in finish quality. It starts as a stripe with parallel sides and rounded ends, changes to oval, becoming shorter and wider. Finally it turns into a round shape.
On average a worn tip will spray 25% more paint and require 20% more labor. Worn tips cost time and money…
Generally, airless spray tips are problem free, provided that they are replaced before becoming too worn. Very little negative feedback is reported by contractors using them.
The most important consideration when choosing an airless tip is matching tip to paint specification. The paint manufacturer will make a recommendation for orifice size and usually fan size as well. Generally speaking architectural coatings can be applied with a 4050 psi rated tip and heavy industrial coatings applied with a 7500 psi tip.
Another important consideration is ensuring that 4050 psi rated tip isn’t used on a 7500 psi rated pump. Maximum pressure specification have a safety factor built in to protect the operator against an injection injury. While it may be tempting to use a 4050 psi rated tip on a 7500 psi rated pump for cost or finish reasons, there is a substantial injury risk in doing so.
For a given tip orifice, a wider fan delivers a thinner coat, less defined spray pattern, more overspray and faster coverage on broad, open surfaces. A narrower fan delivers a thicker coat, more defined spray pattern, less overspray and better control when spraying small or confined surfaces.
To maximize productivity and lower labor costs, choose a tip with the right fan size. In general, a spray tip with a larger fan size increases production with less control, and a smaller fan size decreases production with more control.
Suppose your sprayer has a flow rate of 0.38 gpm (1.4 Lpm), and you want to spray latex paint with a 0.017 in. (0.43 mm) tip.
The Tip Charts show that the 0.017 tip has a flow rate of 0.31 gpm (1.17 Lpm).
The Verdict? You can use the 0.017 tip, because it has a flow rate lower than the maximum flow rate of your sprayer.
The three digits represent tip size (fan and orifice) and indicate the amount of paint that flows through the tip. The first digit is half of the fan width (#5 x 2 = 10 inch fan width). The last two digits are the size of the tip orifice in thousandths of an inch. Your actual flow rate will depend on your spraying pressure and the material you are using (high pressure equals more flow; heavier paints equals less flow).
Graco RAC X series tips range from No.2 (4″) to No.18 (36″) fan and .007″ to .071″ orifice. Graco RAC XHD series tips range from .007″ to .049″ orifice and No.2 (4″) to No.20 (40″) fan. Keep in mind that, within these ranges, not every size and fan combination is available.
Do not try to increase the area covered with each pass by backing the gun away from the surface. From farther away, less paint will reach the surface and go to waste as overspray.
The Solution? Use a tip with a larger fan and orifice. Remember, if you use a tip with a larger fan but not a larger orifice, the film build will be less, and you’ll have to move the gun slower.
