Getting to know how each control impacts performance is important for making adjustments with your air spray gun. For example, common problems like a splattery spray, thick coat, dry spray, or too much overspray can all be corrected by changing the fluid or air ratios.

Understanding Your Spray Gun's Controls

Air spray guns have three main controls: the fluid adjustment knob, the air adjustment valve, and the fan pattern adjustment. The fluid screw controls the volume of paint flowing through the nozzle. Turning this in (clockwise) reduces flow, while turning it out (counter-clockwise) increases flow. The air valve controls how much atomizing air mixes with the paint—more air creates a finer spray pattern. Finally, the fan adjustment changes the shape of the spray from round to wide fan for broader coverage.

1. Air Pressure:

This is arguably the most critical adjustment, influencing paint atomization, flow rate, and pattern size. Adjust the pressure regulator on your spray gun and air compressor to achieve the desired results:

Low pressure: Leads to uneven spraying, poor material transfer, and visible orange peel texture.

High pressure: Creates excessive overspray, paint runs, and potential damage to the spray gun.

The ideal pressure depends on several factors, including:

Paint type: Thicker paints require higher pressure for proper atomization, while thinner paints may require lower pressure to avoid runs.

Spray gun type: HVLP guns typically operate at lower pressure (10-20 PSI) than conventional guns (30-60 PSI).

Project requirements: A finer finish might require slightly lower pressure than a heavier coating.

2. Fluid Flow:

Controlling the amount of paint released from the nozzle directly affects the thickness of your paint coat. Adjust the fluid control knob on the spray gun to achieve the desired flow rate:

Low flow rate: Results in a thin, dry coat, inadequate coverage, and potential for visible brush strokes.

High flow rate: Leads to thick, wet coats, potential for runs and sags, and increased material usage.

Like pressure, the ideal flow rate depends on the paint type, spray gun type, and project requirements. Experiment and observe the spray pattern to find the sweet spot for smooth, even coverage.

3. Fan Pattern:

This adjustment determines the width and shape of the spray pattern, impacting the speed and efficiency of your painting process. Adjust the fan pattern knob on the spray gun to achieve the desired width:

Narrow fan pattern: Ideal for detailed work, precision lines, and targeting small areas.

Wide fan pattern: Efficient for covering larger areas quickly, but requires more attention to avoid overspray and uneven coverage.

Choosing the appropriate fan pattern depends on the size and complexity of your project. You can always overlap spray passes to achieve even coverage with a narrower pattern.

4. Trigger Pull:

The way you pull the trigger impacts the consistency of paint flow and the overall control you have over the spray gun. Here are some key points:

Pull the trigger smoothly and steadily: Avoid jerking or rapid pulling, which can cause uneven paint application and splatters.

Maintain a consistent trigger pull throughout the spray stroke: This ensures a continuous flow of paint and a smooth finish.

Release the trigger slowly at the end of the stroke: This prevents splatter and ensures clean termination of the paint line.

The AEROPRO A610 LVLP air spray gun elevates your painting experience with its top level of adjustability, allowing you to achieve satisfying accuracy and control over every project. 

The desired pattern, volume of fluid output and fine atomization can easily be obtained by regulating the pattern adjusting knob, fluid adjusting knob and air adjusting knob. Precise adjustments minimize paint waste and overspray, This empowers you to achieve smooth, controlled spraying even at low pressure, perfect for delicate applications.

Application: Automobile painting and refinish painting, carpentry, decorative painting, yacht and boat building. Suitable for water-based paint spraying.
