High Volume Low Pressure (HVLP) feed spray guns are used in a wide range of applications, from automotive painting to furniture staining. This type of spray gun has been around since the 1950s and has become increasingly popular in the last few decades due to its ability to reduce overspray, improve atomization and deliver a more even finish. However, its use requires a specific set of HVLP compressor requirements to ensure optimal performance. In this article, we’ll take a closer look at these specific requirements and how they can help you get the most out of your HVLP feed spray gun.
What is HVLP?
HVLP is a type of spray gun technology that is designed to reduce the amount of paint that ends up in the atmosphere, as well as improve the spray pattern of the material being applied. The technology works by spraying the material at a much lower pressure than traditional spray guns. This lower pressure reduces the amount of overspray and produces a more even finish.
HVLP Compressor Requirements
In order to get the most out of your HVLP feed spray gun, there are a few specific compressor requirements that must be met.
1. Pressure Rating
The pressure rating of the compressor must be at least 3.0 CFM (Cubic Feet per Minute) at 40 PSI (Pounds per Square Inch). This is the minimum pressure rating required for most HVLP spray guns. It is important to note that some spray guns require higher pressure ratings. Therefore, it is important to check the specifications of your spray gun before purchasing a compressor.
2. Air Tank Capacity
The air tank capacity of the compressor should be at least 5 gallons. This is the minimum size required to ensure optimal performance of the HVLP feed spray gun. Larger tanks will allow the compressor to maintain a consistent pressure, which is important for the proper operation of the spray gun.
3. Air Delivery Rate
The air delivery rate of the compressor should be at least 7.5 SCFM (Standard Cubic Feet per Minute). This is the minimum air delivery rate required to ensure the proper operation of the HVLP feed spray gun. Higher air delivery rates will allow for more consistent pressure, which is important for achieving the best results.
Conclusion
HVLP feed spray guns are a great option for a wide range of applications, from automotive painting to furniture staining. However, in order to get the most out of your spray gun, you must ensure that your compressor meets the specific HVLP compressor requirements. By following the guidelines outlined in this article, you can ensure that your HVLP feed spray gun will perform optimally and produce the best results possible.
