HVLP vs. LVLP: Understanding the Differences

Types of Paint Guns

Paint guns are classified based on the technology they employ to atomize paint. The two most common types are High Volume Low Pressure (HVLP) and Low Volume Low Pressure (LVLP).

HVLP vs. LVLP: A Detailed Comparison

HVLP paint guns operate with a higher volume of air at a lower pressure, typically around 10-15 psi. This results in a larger spray pattern with less overspray, making them ideal for large surfaces such as cars and walls. HVLP guns are also more efficient than LVLP guns, as they waste less paint. However, they require a larger compressor and can be more challenging to control for finer details.

LVLP paint guns, on the other hand, use a lower volume of air at a higher pressure, typically around 25-35 psi. This creates a smaller, more concentrated spray pattern with minimal overspray. LVLP guns are better suited for smaller areas, such as furniture or automotive touch-ups. They also provide greater control and precision, making them ideal for intricate detailing. However, LVLP guns are less efficient than HVLP guns and require a smaller compressor.
