What happens here

Learn to decipher the three-digit code found on airless spray tips, which provides essential information about its performance. The first digit, when multiplied by two, indicates the fan width in inches when spraying 12 inches away from the surface. For example, a '5' in a 515 tip means a 10-inch fan width (5 x 2 = 10 inches). The last two digits represent the orifice size in thousandths of an inch (also known as mils or thou). For the 515 tip, this means a 0.015-inch orifice. A larger orifice allows more paint to pass through, affecting flow rate and atomization.

Goal: Understand the meaning of the three numbers on an airless spray tip.
