What adjusts the fan width of spray and where is it usually found?

The ability to adjust the fan width of a spray is essential for achieving the desired coverage and pattern during painting. This adjustment is typically found at the top of the spray gun. When the fan width adjustment is located at the top, it allows the user to easily modify the spray pattern to match the specific requirements of a project.

By rotating or sliding the adjustment at this position, the painter can widen or narrow the spray pattern, providing greater control over how the paint is applied. This is particularly useful when working on surfaces of varying size and texture, as it helps ensure an even application with minimal overspray.

The other options refer to different adjustments or features that do not pertain to fan width control. For example, fluid adjustment commonly controls the flow of paint and is usually found at the rear, helping manage the thickness and amount of paint being delivered. An air pressure knob adjusts the pressure of the air used to atomize the paint and is typically located on the side, while a paint viscosity knob, if present, is used for adjusting paint thickness and is usually located at the bottom. None of these options specifically adjust the spray fan width, making the top adjustment the correct choice for this function.
