The first 3 didgits specify the series of tip:
200 = T93R Contractor
|Double this number to determine the fan width when spraying 12" (30cm) from the surface. Depending on pressure and material actual width may vary by up to 2# (5cm).|
|The last two digits specify the flow of fluid through the tip - This is the orifice. This opening controls the amount of fluid that flows through the tip. The pressure you are spraying at also has an affect on flow - more pressure equals more flow.|
Same fan width - difference orifice sizes: The example below demonstrates the difference between tips with the same fan width, but increasing orifice sizes. The larger to orifice, the more coating you apply using the same spray pressure and hand-speed as you spray.
Different fan width - difference orifice sizes: The example below demonstrates the difference between tips with the same orifice size, but increasing fan sizes. The same amount of coatings is applied over a larger area - or less coating per square inch using the same pressure and hand speed as you spray. When necessary, remember to size up or down you orifice as you size up or down your fan width if you want to apply the same amount of coating per square inch.
