How do I know my spray tip size?
Understanding the Numbers
- The first digit is half of the fan width, the “5” in “517” equals a 10 inch spray fan width (5 x 2 = 10)
- The last two digits are the size of the tip opening in thousandths of an inch, the “17” in “517” means the tip hole size is . 017 inch.
What size tip should I use for single stage paint?
1.5mm, 1.6mm-Multifunctional nib suitable for primer and single-stage paint. However, thinner coatings pose a risk of orange peel because they cannot be properly atomized. These sizes are also ideal for varnishes. 1.7mm, 1.8mm-1.7mm is the minimum size that most primers should use.
What PSI should you spray primer?
To begin, set it at 50 psi. Close the air volume control knob (usually located beside where the air hose enters the gun) and with the trigger pulled, open it to the point where the air volume starts to stay the same, and then stop.
What is the best PSI to spray clear coat?
When spraying base coat clear coat systems, you want to spray at 26-29 PSI. You measure this PSI by pulling the trigger and letting air flow through the tip of your gun with your dial or digital readout saying 26-29 PSI.
Is a 1.3 tip for base coat?
The 1.3mm is a great general clear coat tip and is also good for thinner base coats, waterborne and single-stage paints. Too thick of a paint won’t flow well through this size, though. 1.4mm – Great all-purpose size. Works well with most base coats, and even thicker clears.
What size airless sprayer tip do I Need?
Airless sprayers will often cite a maximum spray tip size, expressed as e.g. Max. tip size 0.051” (or 1.2954 mm). This means the manufacturer suggests to use a spray tip number whose ending does not exceed x51.
What do the numbers on a sprayer tip mean?
The second two numbers are the orifice size of the tip, in thousandths of an inch, that determines how much fluid will leave the spray tip. For example, a 515 tip will spray a 10-inch-wide fan and have a 15-thousandths of an inch orifice.
What does the tip of a spray gun do?
Not only does the tip determine how much fluid will leave the gun when you pull the trigger, the spray tip also determines how wide a spray fan the gun will create. Choose a tip with an orifice size rated for the paint or coating you’ll be spraying.
How far can the conventional air atomising gun spray?
Remember at all times that the Conventional Air Atomising gun is designed to spray at 6 – 8” inches and deviation from this distance by altering fluid flows and air pressures is not good practice. It could lead to other paint defect problems. The gun must not be excessively arced or tilted while spraying, as shown in Figures 3 and 4.
