New: Fine Finish Low Pressure Tips by Graco

Written by on January 29, 2017 in Sprayers, Uncategorized with 9 Comments

If you have been following TCR for very long, you have probably noticed a constant focus on spraying at lower pressures. The new series of Graco RAC X Fine Finish Low Pressure tips are a compelling and EASY step in that direction.

What to look for…

Controlling airborne mist and overspray does two things for us. First, it makes the working environment safer – we are less likely to wear and breathe the material we are spraying. Second, there is less contamination settling into finishes as they dry.

HOW you get there is a function of more variables. Flaws in technique cause overspray, no matter how good the machine is…it is only as efficient as the operator.

Product and pressure also come into play, regardless of whether you are spraying airless, air assisted or HVLP. In the end, you need a good, clean finish.

Running too high with fluid pressure is the most common mistake we see when training painters. Crank it up and go fast. When more fluid is pumped and atomized, you have to move faster. This can create mistakes that cause overspray and contamination.

Slow Down to Go Faster

Fine Finish Low Pressure tips (or FF LP) are engineered to allow us to work with our pumps set at lower pressures. Using airless, it is expected that you will be able to cut pressure in as much as half using a low pressure tip. With air assisted, we have already consistently observed 25-30% reduction in fluid pressures with medium viscosity latexes.

Fine Finish Low Pressure tips in production

One big benefit is that lower pressures are easier on your pump. If your machine is working at lower pressure, it is not working as hard. Material usage will be reduced because of better transfer efficiency. The fine finish low pressure tips should also last longer than a regular tip.

Your production rates will not change, you won’t go slower. You can still choose the same size orifice for the product you are going to spray, you will be able to do it cleaner and just as fast – the only difference will be that you are doing it at a lower pressure. This is an easy move toward efficiency in spraying.

    Just got done with 7 sets of cabinets + doors with a 310 fflp tip with graco 390 airless and they are glass smooth. These tips work exactly how they say and are worth every penny of the high price. I have pumped about 70 gal so far through this tip and still works like day 1. For this particular tip size I found 1500 psi to be just right. The larger orfice sizes need a touch more pressure but still lower than conventional tips.

      Can you tell us what material you used? I am interested in using the new tip with BM Advance. Have cabinet doors/drawers, closet bi-folds and interior doors. Don’t know if I should use the 312 or 310 tip. Or go up a size to 412 or 410. Any feedback would be great. Thanks.

    So what is really the difference between these and the normal ff tips? I’m guessing even lower pressure then you would use for the normal ff tips?

  3. Scott, these fine finish low-pressure tips are great news! I can’t wait to try them with our Graco 395 air assisted airless. We’ve got five separate sets of cabinets with doors in a home that we are doing right now! I sure hope I can get a handful of these tips by tomorrow or Tuesday, LOL! Thanks for sharing keep up the great work!

    Got some to try out on my Wagner. Need to get a RAC X Tip Guard first though.
