Adjusting the spray width of a high-pressure airless paint sprayer is crucial for ensuring spray quality and efficiency. Here are detailed adjustment methods and some expanded content to help you better understand and master this skill.
Choosing the Right Nozzle
The size of the nozzle directly affects the spray width and thickness. Nozzle sizes are usually indicated by three digits, such as a 515 nozzle, where the first digit (5) represents the spray width, and the last two digits (15) represent the nozzle orifice size. Each unit increase in nozzle width roughly increases the spray width by 2 inches (about 5 cm). Choose the right nozzle according to your specific spraying needs and the material being sprayed.
Adjusting Spray Pressure
Spray pressure is one of the critical factors affecting the spray width. High-pressure airless paint sprayers, including models from SCENTURY, typically come with a knob or control device to adjust the spray pressure. Proper spray pressure not only ensures an even spray but also prevents excessive overspray and material wastage. Adjust the spray pressure based on the viscosity of the spraying material and the desired spray width.
Adjusting Spray Distance
Spray distance refers to the distance between the nozzle and the surface being sprayed. Generally, the closer the spray distance, the narrower the spray width; the farther the spray distance, the wider the spray width. Adjust the spray distance according to your specific spraying requirements and environment to ensure optimal spraying results.
Adjusting the Spray Angle
The spray angle also has a certain impact on the spray width. Typically, the spray angle should be maintained at 90 degrees to ensure an even spray. If you need to adjust the spray width, you can slightly change the spray angle, but be careful not to deviate too much to avoid affecting the spray quality.
Controlling Spray Speed
Spray speed refers to the speed at which the spray gun moves over the surface being sprayed. The faster the spray speed, the narrower the spray width; the slower the spray speed, the wider the spray width. Adjust the spray speed according to the characteristics of the spraying material and the spraying requirements to ensure an even spray.

Selection of Spray Materials
Different spray materials have varying impacts on the spray width. For example, latex paint and oil paint may have different spraying effects. Choose the right spray material and adjust accordingly based on the material’s characteristics to effectively improve the spray results.
Maintenance of Spray Equipment
Regular maintenance of the spray equipment, including Graco airless sprayer parts and Graco pump repair parts, ensures the cleanliness and normal operation of the nozzle and spraying system, effectively preventing issues like uneven spray width. When cleaning the nozzle, use specialized cleaning tools and solutions to ensure the nozzle is unobstructed.
Safety Operation Precautions
When adjusting and using a high-pressure airless paint sprayer, always observe safety precautions and wear necessary protective gear, such as safety glasses, masks, and gloves. Avoid situations where spraying liquid splashes or accidental spraying occurs to ensure operational safety.
