HVLP Spray Guns, or High Volume Low Pressure spray guns, are tools used for painting and finishing surfaces. They operate by delivering a high volume of paint at a low pressure, which helps to reduce overspray and improve paint transfer efficiency. This makes them popular for both professional and DIY projects, as they provide a smooth finish while minimizing waste. These spray guns are often used in various applications, including automotive painting, furniture finishing, and home improvement projects. They can be powered by air compressors or come as electric models, making them versatile for different user needs and preferences.
