HVLP Meaning

HVLP sprayers deliver high air volume (10-30 CFM) at low pressure (10 PSI or more). In this system, atomization occurs by air volume not because of air pressure, which reduces the forward velocity and results in a softer spray.

The softer spray allows the material to stick to the part more and not bounce off into the air, thus causing less air pollution and paint waste. Moreover, the market offers two HVLP options.

One is Turbine-powered, while the other is Pneumatic spray guns. Therefore, beginners and inexperienced DIYers will efficiently operate HVLP spray guns because of their user-friendly design and easy work mechanism. Here is an in-depth review of HVLP spray guns that I have used for many projects.

HVLP Turbines

The most popular power-painting tool among professionals is HVLP turbines. The HVLP units come in handheld models such as HomeRight Finish Max sprayer that feature an integrated turbine powerhouse. You can also buy floor-standing machines with an external power unit.

Plus, the medium-scale applications of HVLP turbines include waterproofing decks, painting fences, upgrading furniture, doors and trims.

Pneumatic Guns

An external compressor is required for pneumatic HVLP guns to atomize and propel your coating medium. The paint density, air volume, and pressure can be adjusted, making them versatile than turbines. Because of this reason, they’re preferred by contractors.

However, these sprayers are more costly than HVLP turbines. Also, pneumatic units require considerable setup time and need some experience to operate.

LVLP Meaning

Low volume Low-pressure sprayers have the combination of the best features of HVLP and conventional air sprayers.

They are only available as compressor-driven units. These sprayers create better atomization to produce quality finishes.

LVLP spray guns requires very little air pressure for operation, so a small air compressor can be used.

Air consumption for this spray gun ranges from 3.5CFM to 3.9CFM at 30 psi. The optimal working pressure ranges from 25 to 45 psi.

I’ve tested LVLP spray guns for different projects in this year, so you can read the review of these models to learn more about them.

Comparison Factors Of LVLP vs HVLP Spray Gun

1. Transfer Efficiency

Depending on the model of the spray gun, paint transfer efficiency also differs depending on HVLP or LVLP sprayers.

The transfer efficiency rate of an HVLP paint sprayer such as Wagner 590 or Wagner control spraytech ranges from 60 to 65 percent. However, some manufacturers state that their products are capable of delivering up to 75 percent.

The performance of HVLP is better than other painting methods, such as brushes and rollers, but in terms of efficiency, LVLP still beats HVLP.

On the other hand, LVLP is a cost-efficient option for painters like Sprayit 33000 and 33500 spray gun, and it offers transfer efficiency of up to 70 to 80%. So, there is less paint spreading all over the place when using LVLP.

Plus, It is more eco-friendly to use LVLPs than HVLPs since they generate less waste, save more money, and are less expensive.

2. Project Scale Size ( hVLP vs lVLP vs Airless )

HVLP sprayers (pneumatic or turbine) are excellent for small to medium projects— exterior or interior walls, decking, furniture, and cabinet spraying.

If you wish to perform larger painting projects, then you should prefer an Airless sprayer. Airless machines provide better coverage than either LVLP or HVLP sprayers, but with only about 50% transfer efficiency.

However, LVLP sprayers have a smaller fan pattern than HVLP turbines, usually between 8 and 10 inches, so they tend to take more time to complete medium-sized projects.

LVLP units are popular for fine-finishing work because of their low overspray, thin coverage, and quality finish. Many car spraying professionals prefer LVLP systems for this reason.

3. Compatibility With Compressor

HVLP turbines do not require a compressor. On the other hand, If you decide to buy a Pneumatic HVLP gun, then you need the correct compressor; otherwise, your paint will be nothing but a drip.

The output of a compressor is typically measured in PSI and CFM. The pressure required by an HVLP pneumatic spray gun is around 15 to 35 PSI, so most home compressors can provide it.

CFM is another essential factor that you cannot ignore. Be sure to check the manufacturer’s specifications for the gun you intend to use. HVLP guns require more than 10-25 CFM than other guns, so users must size their air compressor accordingly.

To learn more about the technical issue, please read the basics about compressor requirements.

LVLP spray guns require a lower PSI to operate correctly (10 PSI), so you can use almost any air compressor, and it will work fine.

Even the cheapest air compressor will work for LVLP spray guns. But using a cheap and low-quality air compressor is not recommended since the air compressor is one of the most important factors contributing to the spray gun’s performance.

In contrast, LVLP guns require a CFM range of 5-18 due to the low pressure. Hence, the LVLP unit sprays faster, atomizes better, and uses less airflow to accomplish quality finishing.

4. Painting Mediums– What type of paint is best for HVLP or LVLP?

HVLP creates a good finish, though it is not quite as impressive as LVLP. Metallic paints and thicker materials works great with HVLP paint system. However, most paint materials still need to be diluted to get a suitable viscosity.

You can spray a wide range of materials like enamel, acrylic, primer, paint, stain, and even Latex with turbine HVLP sprayers. 

While pneumatic HVLP guns are usually compatible with multi-coatings and can propel viscous fluids with proper thinning requirements, at this stage, selecting the spray tip is also an important consideration. The large diameters are better suited for paints with a thicker consistency, like Latex. 

On the other hand, LVLP sprayers are not recommended if you wish to paint thicker material. It works best for thin materials such as varnish, clear coats, thin stains, and lacquers. As per my experience, LVLP is not good for latex paints.

The problem persists with standard latex paints, even when thinned considerably because LVLP sprayers can operate on smaller compressors and requires less air pressure. An LVLP system generally uses ten psi or less. Thus, LVLP guns are a perfect fit for home systems.

5. Value For Money

HVLP turbine sprayers are the best value option for beginners and casual DIYers in the marketplace because they don’t require an additional compressor. Unlike turbines, pneumatic spray guns require a compressor, which makes them more expensive.

In contrast, LVLP machines are a more cost-effective option than HVLP machines, which require high volumes.

How to set up and use your LVLP spray gun?

In this section, it is all about setting up my paint gun, specifically LVLP (Low Volume Low Pressure) ones. I have got my compressor sorted out, and now I am ready to get that air flowing for a perfect spray. Let’s dive into setting up the spray gun.

There are three controls we need to be familiar with:

1. Top Control: Adjusts the fan pattern.
2. Middle Control: Manages the fluid flow, determining how much material comes out.
3. Air Control: Regulates air pressure, and we’ll use an air regulator for this.

Now, let’s set up the spray gun step by step:

1. Air Control: Open it wide since we’re using an air regulator. We’ll adjust the pressure later with the regulator.
2. Fluid Control: Turn it all the way out, then squeeze the trigger and gradually turn it in until you feel the needle against the trigger for full fluid.
3. Fan Control: Start with the fan closed completely. Open it gradually until you get the desired fan pattern.

Keep in mind:

• Adjust the air pressure with the regulator.
• Be cautious with the fan pattern to avoid too much overspray or running the material.
• Aim for a football-shaped pattern, about 5 to 7 inches away.

How do you spray paint with a HVLP gun?

I’m sharing the process of painting with an HVLP spray gun. Let’s start with breaking down the basic controls and then move on to some demonstrations of painting techniques.

Parts Breakdown:

The HVLP spray gun typically consists of several parts: the cup, nozzle, fan control, paint volume control, air volume control, air inlet, trigger, and needle. Understanding these components is crucial for efficient use.

Cleaning:

Before you begin, it’s essential to disassemble the gun for cleaning. Parts like the cup, nozzle, and needle need to be scrubbed thoroughly to ensure a clean application. Pay attention to ports and ensure they’re clear.

Needle Options:

HVLP guns often come with multiple needle options, like 1.4 and 1.8, suitable for different paint viscosities. Picking the right needle is crucial for the perfect finish.

Fan Control:

The fan control adjusts the width of your spray pattern. Closed gives you a circle pattern, while open provides a wider fan. This control is crucial for adapting to different painting scenarios.

Paint Volume Control:

This control paint flow by starting with a low volume and adjusting gradually. It’s easier to add more paint later than deal with excess.

Air Pressure:

Maintaining the correct air pressure is crucial. Too low, and you get speckles; too high, and you get overspray. Finding the sweet spot, usually around 35 psi, is key for a good finish.

Paint Filtering:

Before you start, always filter your paint to remove any impurities. Ensure a smooth application by filtering paint to remove particles.

Painting Techniques:

When painting, consider the distance between the gun and the surface. Adjust the fan pattern based on what you’re working on—tighter for small parts, wider for larger areas. Explore varied pressures and volumes to find your project’s best settings.

Is HVLP good for painting cars?

It is possible to paint cars (including car hood, bumper painting)with HVLP spray guns, but they may not be the best option for certain types of automotive painting.

Generally, HVLP spray guns produce fine finishes with minimal overspray, making them suitable for painting cars where a smooth, high-quality finish is required. However, HVLP guns need large volumes of air to operate, which can be challenging in a home garage or small body shop.

The price of HVLP guns can also be higher than other types of spray guns for some automotive painting projects. On the other hand, heavy-duty industrial applications and larger surfaces can be covered with LVLP spray guns.

HVLP vs LVLP for Latex Paints

LVLP has a fine-atomized spray that is great for clear coats, single stage enamels and painting vehicles. It also paints at a slower rate than an HVLP, which is great for detail painting. However, an HVLP is ideal for thinned paints like latex and also paints more quickly than an LVLP.

LVLP Vs HVLP for Woodworking

When it comes to woodworking, both LVLP and HVLP spray guns have their advantages. LVLP guns, with lower air volume, are often favored for smaller woodworking projects due to reduced overspray and precise application.

On the other hand, HVLP guns, offering a higher volume of air, excel in larger projects, providing efficient coverage with minimal waste. The choice depends on project scale and desired finish.
