On an airless paint sprayer, what is responsible for the pattern of the paint?

• A. Activator
• B. Compressor
• C. Orifice
• D. Actuator

Answer: (C)

The spray pattern in an airless sprayer comes from the opening in the spray tip—the orifice. As paint is forced through that small hole, its size and shape determine how it exits as a cone or fan, controlling the pattern and atomization. A larger orifice yields a wider pattern with more paint, while a smaller orifice produces a narrower pattern with finer atomization. The other options don’t shape the spray: an activator is for chemical-cure aspects, a compressor isn’t used to set the pattern in airless systems, and an actuator is simply a moving part, not the pattern control.
