The HVLP and the LVLP spray guns are two of the most popular spray guns available on the market in 2022.
However, a ton of people do not know the differences between these two spray guns. If you are not an expert, we do not expect you to know all the subtle differences since both these guns look quite similar.
So, in this guide, we are going to take a close look at both these spray guns so that you do not end up making the wrong choice while buying one. Our team of experts has extensively tested both these spray guns and have shared the details with us.
After reading this article, we are confident that you are going to know all the nitty-gritty of both these spray guns.
So, without any further ado, let us get right into it.
HVLP vs. LVLP Spray Guns
An HVLP is one of the most commonly used spray guns out there. HVLP means “high-pressure-low-volume.” In simple words, these spray guns are capable of producing high volume output using very low pressure.
What this actually signifies is that you basically spend less material while maintaining high color quality. HVLP spray guns are known to produce around 100 CFM at 3-8 PSI.
However, their pricing is a little higher than LVLP guns since they use a lot more compressed air. HVLP spray guns come in handy for people who are inexperienced and for DIY purposes.
Keep in mind – they are not the best choice when it comes to professional purposes as they perform a lot slower than LVLP spray guns. Furthermore, they use larger compressors and often do not work well with thicker paints.
HVLP spray guns save a lot of materials and avoid wastage because of their high volume, which allows the paint to end up only on the surface. Also, they are ideal for projects that demand immediate solutions. Since it is one of the most commonly used spray guns, it means tech support and training are readily available.
Advantages Of HVLP
- It is great for beginners and DIY projects
- High-quality finish
- Less material waste
- Appropriate for being used on metallic surfaces
Disadvantages Of HVLP
- Requires larger air compressors
- It does not work well with thicker paints
- Works slower than LVLP spray guns
LVLP spray gunsare some of the premium options on the market. LVLP means “low-volume-low-pressure.” This type of spray gun is popular for delivering top-notch transfer rates, which means premium finishes and less waste. Additionally, it demands just about 10 PSI, which essentially means that you are free to use any kind of air compressor with this spray gun.
LVLP spray guns perform best with thinner paints. So, if you intend to apply metallic paints or work on surfaces that are sticky, we suggest going with HVLP spray guns. When it comes to design, finding out the differences can be quite challenging since there is not much. If you have a keen eye, however, you will definitely be able to spot the subtle differences.
Both HVLP spray guns and LVLP spray guns are built ergonomically in order to reduce fatigue levels.
Advantages Of LVLP
- More affordable than HVLP spray guns
- Uses lower PSI
- Works perfectly with waterborne paints
- Sprays a lot faster
- Does not need a very big air compressor
Disadvantages Of LVLP
- Its pattern size is very small
- It does not work well on sticky surfaces
HVLP vs. LVLP – The Differences!
In this section, we will delve a little deeper and find out the exact points of differences between these two popular spray guns. You will have complete knowledge of both HVLP and LVLP spray guns after you go through this section.
Transfer Efficiency Rate
The transfer efficiency rate of spray guns varies from model to model; it also greatly depends on the kind of spray gun you are using – HVLP or LVLP.
Talking about transfer rates, LVLP spray guns do a better job as they can transfer up to 80%, which essentially means that there will be less paint wasted. Hence, it makes LVLP spray guns a more environment-friendly option.
As far as HVLP guns are concerned, the transfer efficiency rate is expected to linger around 65% to 70%. Since the transfer rate is lower than LVLP spray guns, it is a less efficient option. A lower transfer efficiency rate basically means more paint is wasted.
However, both LVLP and HVLP are a lot better than traditional spray guns that provide a transfer rate of barely 35%.
Width Of The Fan Patterns
The width of the fan patterns is yet another major difference between HVLP spray guns and LVLP spray. Not only does it affect its overall performance, but it also affects our comfort of using these products.
When it comes to the width of fan patterns, HVLP spray guns are the clear winners as they offer a larger pattern width than what LVLP spray guns have to offer. An LVLP spray gun usually offers a width between 8 and 10 inches which is deemed small.
Even though this might not be the biggest issue for most people, it is worth keeping in mind, less pattern width means more painting time. It becomes particularly more important for people who are starting new, smaller width fan patterns that affect the quality.
Usability is more of a subjective thing. What seems easy to use for you may not necessarily be easy to use for somebody else. It all boils down to the experiences you have of using a spray gun.
That being said, HVLP spray guns have been on the market for a long time. As we have already mentioned, you are likely to find better training and tech support while using HVLP spray guns simply because they have been around longer.
On the other hand, LVLP guns are quite new in the business, and there is a high possibility that a lot of people have not used this variant. So, when you buy this spray gun, keep in mind that you are not going to find tech support and training that easily.
We would strongly advise you to buy spray guns from a reputed brand as they provide detailed instructions, be it HVLP or LVLP spray guns.
The pressure needed to operate both these spray guns is a very prominent difference between them. As the names suggest, HVLP spray guns provide a high volume but a low pressure which means it requires a big air compressor to do the job.
The lion’s share of HVLP spray guns works at around 20 CFM and 50PSI, which implies that you would need nearly an 80-gallon tank. On the other hand, LVLP guns will work between a range of 10 and 25 PSI and 5 CFM, and this is where LVLP spray guns beat HVLP spray guns.
With an LVLP spray gun, you are free to use any air compressor, making them the more suitable option.
Both HVLP and LVLP spray guns come in different brands and models, so the prices keep varying. You can expect to get the lower-end models of both these products for under a hundred bucks. However, if you are looking for a brand that offers better specifications and advanced features, then you will have to spend more money on HVLP spray guns than LVLP.
The price of a quality HVLP spray gun can go above $500, whereas top-notch LVLP guns barely hit beyond $400. Also, keep in mind that while buying an HVLP spray gun, you will need to buy a larger air compressor as well, which makes it all the more expensive.
HVLP Spray Guns Are Best For:
Both HVLP and LVLP spray guns are some of the best spray guns out there. Not only do they perform a fantastic spray-painting job, but they are also quite efficient. However, both these guns work on different mechanisms, and hence they are perfect for different scenarios.
HVLP spray guns are perfect for people who do not have much experience in spray painting. Since their spraying rate is on the lower side, it is ideal for DIY projects. HVLP guns tend to waste materials, and hence they are not recommended for professional purposes as they increase the cost of the overall project by a lot.
Furthermore, HVLP spray guns require larger air compressors which makes them less mobile. So, it is better to use HVLP spray guns at home rather than on-site.
LVLP Spray Guns Are Best For:
Since LVLP spray guns are not that common, learning how to use them can be quite a hassle. This is why they are not ideal for DIY projects and people who have very little knowledge of spray painting.
LVLP spray guns, however, are perfect for professionals since they require small air compressors and waste a lot fewer materials. Not only are they portable, but they spray super fast as well. All these factors make them the absolute choice for professionals.
The transfer efficiency is like the cherry on top as it makes them the ultimate cost-saving spray gun option for professionals.
