HVLP systems, or High Volume Low Pressure systems, are spray painting tools designed to deliver a fine mist of paint with minimal overspray. They operate by using a high volume of air at low pressure, which allows for a more controlled application of paint. This results in a smoother finish and reduces waste, making them popular for both professional and DIY projects. These systems typically consist of a spray gun and a turbine or compressor that provides the necessary air pressure. HVLP spray guns are often used in automotive painting, furniture finishing, and other applications where precision is essential. Their efficiency and ease of use make them a preferred choice for many painters.
