Who is right about the distance HVLP spray guns should be held compared to older models?

Technician A is correct regarding the distance HVLP (High Volume Low Pressure) spray guns should be held compared to older models. HVLP spray guns are designed to utilize a higher volume of air at a lower pressure, which allows for finer atomization of paint and a more controlled application. As a result, these guns are typically operated at a closer distance to the surface being painted compared to conventional spray guns. This closer distance helps minimize overspray and allows for better control of paint coverage and consistency.

In contrast, older models, which often operated at higher pressures, required a greater distance to achieve an even spray pattern without causing an excessive buildup of paint in one area. Therefore, Technician A’s claim reflects the understanding that HVLP spray guns should be held closer to the surface than older spray equipment for optimal performance and results.
