HVLP (High Volume, Low Pressure)
HLVP spray guns are similar to conventional air spray guns in that they use pneumatic fluid atomization. However, HVLP guns use a higher volume of air at a lower pressure. The lower pneumatic pressure allows for less overspray. HVLP guns are commonly used in the automotive, general metal, aerospace, architectural coating, furniture finishing, and other fine finishing applications where material waste is of a great concern. HVLP spray guns are often required by U.S. Environmental Agencies for high usage customers. HVLP spray guns come in a variety configurations; siphon feed, gravity feed, and pressure feed.
- Advantages: High transfer efficiency (65% to 75%). Sprays well into recesses and cavities.
- Limitations: Uses a high volume of air. Atomization not as fine as air spray guns.
