There is a large variety of different types of spray guns available for painters, professionals, and newbies. They almost look the same and work on the same principles with a little bit differet. But what suits you depends on your project’s nature and needs.
The work nature of expert painters and professionals is quite different from the work nature and needs of beginners. So choosing the right gun for your job is a hectic task even for experienced DIYers.
When the guns are similar in name and different in output, how you select the right one between HVLP vs. LVLP spray guns is a very tricky question. You need to know the difference between the nature and functions of both guns.
This article will provide you with all information regarding the difference between HVLP vs. LVLP spray guns, and help you to decide the right one for your work.
What Is HVLP Spray Gun?
This (High Volume Low Pressure) gun is a commonly used spray gun among all users. It can produce high volume output at low pressure.
It has been designed in a way that even beginners and inexperienced DIYers can use easily.
The HVLP needs a large powerful compressor than LVLP. It wastes less paint and saves your money. It is an environmentally friendly spray gun that creates a fine finish.
It can handle thicker material at higher transfer efficiency. It is also useful for both small and large projects.
What Is LVLP Spray Gun?
The LVLP (low volume low pressure) spray gun is a new type of gun used for painting.
It is very an outstanding gun for spraying thin materials such as clear coats, lacquers, thin satins, and varnish.
It needs low pressure to work so a small compressor can supply enough airflow to this gun.
LVLP guns usually use 10 PSI or less but they can create an excellent finish with greater transfer efficiency. It wastes less material than HVLP.
It is a very fast spraying machine used for big projects but it doesn’t do well with thick paints. It is very popular with professional users and experienced DIYers.

- #2: The transfer efficiency of the HVLP spray guns is 60-70% which is more than LVLP. So HVLP gun is generally used indoors as it sprays little paint flying into the air.
- #3: Further, transfer efficiency varies from modal to modal as different types of spray guns are used for painting.
#3. Speed Difference
Whether you are a beginner or professional, you always try to complete your project sooner and faster. So the speed of the gun also affects your selection of gun
- #1: HVLP spray guns have large air holes and use more pressure, so they are faster than LVLP.
- #2: Due to higher transfer efficiency, HVLP covers a large surface faster than LVLP.
#4. The Difference In Fan Pattern
- #1: There is also a prominent difference between HVLP spray guns and LVLP spray guns regarding the width of the fan pattern.
- #2: It largely affects the overall performance and using these guns with ease.
- #3: The HVLP spray gun has a larger fan pattern than the LVLP gun is usually between 8 and 10 inches.
- #4: The LVLP spray gun has a smaller fan pattern which causes more painting time and affects the quality of the paint finish.
#5. Difference Between Using Spray Guns
There is another important difference of using between HVLP spray guns and LVLP spray guns. Some users can use HVLP easily while others can’t. All this depends on the skill and experience of the user.
- #1: As HVLP spray guns have been used for a long time, so all painters, professionals, and even beginners know this spray gun well. You may find better tech support and training about this gun.
- #2: While the LVLP spray gun is a new one on the market, most users haven’t used this gun. So you may not find better tech support and training about LVLP spray guns.
- #3: When you decide to buy a gun suitable for your work, you always focus on the easy use and proper tech repairing facility available in the market.
#6. The Difference In The Paint Type You Want To Use
If you test the paint type, both the guns are equal; they can spray any type of paint if you have the correct tip size, paint well mixed, and have sufficient air volume.
#7. Difference Between Cost/Price
Both HVLP spray guns and LVLP spray guns are found on the market in different models, brands, sizes, and prices.
- #1: If you buy a spray gun for a small project, and you are a beginner, you normally need a gun of lower quality; it can be easily available at a low price
- #2: If you want to buy a spray gun for larger projects and you are an expert painter or professional, you need a good quality gun; it will be expensive.

Great article, i have a couple of questions that i cant find the answer anywhere on he net.
1, What are the physical differences inside between hvlp and lvlp guns.?
2, Can you use a hvlp gun as a lvlp by reducing the psi output of the compressor and using lvlp caps? (depends on answer to 1.)
3, Is there a way to change the cfm output of a std compressor
Many thanks and keep up the good work.
Thank you for your comment on my website and for your interest in the differences between HVLP and LVLP spray guns. I am glad to hear that you found my article informative and helpful.
To answer your questions:
#1. The physical differences inside HVLP and LVLP guns relate mainly to the size and shape of the air caps and fluid nozzles, as well as the air pressure required to operate them. HVLP guns use larger air caps and fluid nozzles, and require higher air pressure (typically between 10-20 psi) to atomize the paint. LVLP guns, on the other hand, use smaller air caps and fluid nozzles, and require lower air pressure (typically between 5-10 psi) to achieve the same atomization. The result is that LVLP guns use less air and produce less overspray, making them more efficient and environmentally friendly.
#2. It is possible to use an HVLP gun as an LVLP gun by reducing the air pressure output of the compressor and using LVLP air caps and fluid nozzles. However, it is important to note that this may not produce the same level of atomization and efficiency as a true LVLP gun, as the design of the gun itself is optimized for a specific air pressure and fluid flow rate.
#3. Yes, it is possible to change the CFM output of a standard compressor by adjusting the regulator valve and adding an air dryer and/or filter to improve the quality of the compressed air.
