Here are a few steps to help you decide: 1⃣ The first digit (A) stands for the width of the nozzle stream , we will label it as "A". By multiplying the first digit "A" x 5 cm, we get the stream width we want to achieve when holding the gun 30 cm from the surface. So mathematically this can be written as: Fan width = A x 5 cm Example: If the first digit "A" is 5, then the fan width is: Fan width = 5 x 5 cm = 25 cm This means that holding the gun 30 cm from the surface will result in a fan width of 25 cm. 2⃣ The last two digits (B) - indicate the nozzle orifice size and paint density. The higher the number, the thicker the paint. For example, "517" is a nozzle with a fan width of 25 cm and a nozzle orifice diameter of 0.017 inch.
