There are three main spray painting systems that are popular in various industries today. Out of all of them, the High volume low pressure (HVLP) is the most common one. While we talk about this oil-free high volume low-pressure spray gun, we need to tell you that these are the most affordable spray painting methods prevalent in the market. These spray guns have benefits for the individual customer as well as the industrial sector. The HVLP spray guns are further categorized into three types, and these guns are considered to be of the top quality and offer a fantastic finish during spray painting.
This article is aimed at explaining how you should select the correct spray painting system and how HVLP is beneficial for you.
The Working of HVLP
As the name suggests, the high volume low-pressure spray guns harness a very high volume of air to spread the paint through the gun that requires low pressure. The pressure should be as low as 10 PSI. This low PSI reduces the overspray and it ends up transferring more paint to the surface, which results in a smoother finish.
Understanding the types of HVLP spray guns: Conversion vs dedicated
The very first type of HVLP gun often called a conversion system comprises a conversion gun and an air compressor. This spray gun reduces the pressure to 10 psi and below. For these systems to work efficiently, you need to have an air compressor of at least three horsepower coupled with a tank capacity of 80 litre or more. This is a good method but not as effective as the next one.
The second type of oil-free high volume low-pressure spray gun uses the dedicated system. This system swaps the air compressor for a turbine which is responsible to propel the air through the gun with high volume and low pressure. These dedicated guns are rated by the number of fans they have, the higher the stage, the better would be the rating. These spray guns are smaller and portable. However, they are more efficient than any other HVLP spray systems.
Various benefits of an HVLP
We hope that you have understood the meaning and mechanisms of an HVLP. You might be wondering how these HVLP systems are useful for you. FYI, we are here with some excellent benefits of HVLP for you.
We have already seen that HVLP uses a high volume of air and works with low pressure for a smoother finish of the paint. Further to this, HVLP guns eliminate the chances of moisture that are associated with other types of spray systems. This help the workers to reduce the paint wastage and a faster paint curing.
The dedicated HVLPs are small, compact and easily portable from one place to another. The basic nature of high volume low pressure is that they use less material for any kind of job assigned to them.
Last, these are the best for eco-minded people because they produce very less air pollution than other types of spray guns.
Given the benefits and easy use of oil-free high volume low-pressure spray guns, we are sure that you know which ones to pick up for your next painting project.
