An HVLP spray gun can be the best choice for you if you’re looking for a reliable, cost-effective spray gun. Continue reading to find out more about the spray gun and how it may help you with your finishing process.

High-volume, low-pressure (HVLP) paint sprayers may be adjusted in various ways. Instead of employing a compressor to generate high pressure, as is the case with traditional paint guns, HVLP guns utilize low pressure and a regulator to regulate the flow rate.

As a result, you’ll be able to save money and time while using HVLP sprayer, doing your painting work much more efficiently. You can cut down on paint waste and over-spraying with the help of your HVLP automotive paint spray gun. 

How Do HVLP Sprayers Operate?

When paint comes into contact with the air stream from the nozzle of an HVLP spray gun, it is “atomized,” or broken up into microscopic particles. The fan size and density of HVLP sprayers may be adjusted to suit various applications, from a light mist to a thick coat. The air pressure and paint distribution may be adjusted using the sprayer’s air input, paint basin, and nozzle.

With a pull of the spray gun’s trigger, paint is atomized in the airflow before spraying through the nozzle at high speeds. A correctly adjusted HVLP gun will provide a smooth, uniform coat with little overspray and minimal drying time.

Difference Between LVLP And HVLP

If you’re in the market for a new paint sprayer, you may be puzzled by the differences between high-volume, low-pressure (HVLP) and low-volume, low-pressure (LVLP) paint sprayers. The two different types of sprayers each have their own set of benefits, making it a difficult decision to choose which one is superior.

Below is a full explanation of the differences that exist between spray painters that use low-volume high-pressure and high-volume low-pressure systems to guide you in selecting the sprayer that will meet your needs to the greatest extent possible.

1. HVLP

HVLP stands for High volume low pressure. 

The measurement on the air pressure gauge at the top of the tank should fall between 0.1 and 10 pounds per square inch. Alternatively, it demonstrates that the application has a transfer efficiency of at least 65% is also acceptable.

The painting is only feasible due to the amount of air, not the pressure of the air. It is possible that a milder spray will be provided in order to enable more material to adhere to the component.

Apply to surfaces such as walls, cabinets, and other furniture.

Substances that are thinner that are used as coating materials (latex paint, lacquers, stains)

2. LVLP 

LVLP stands for low volume low pressure.

Because the pores are smaller, there is more air pressure created at the air cap, which leads to an improvement in atomization.

Similar to HVLP, but with holes in the air caps that are somewhat more narrow.

No limit on air pressure exceeding 10 psi.

Uses that are acceptable include applying base coatings, enamel, and clear coats.

Spray guns, including HVLP and LVLP varieties, tend to have excellent build quality. In addition to this, they may be used for a myriad of other purposes. Your choice between the two should be determined by the activities that you want to carry out with it.

Because it does not need any particular level of expertise to operate, HVLP is a fantastic investment opportunity for do-it-yourselfers and beginners. Because it transfers paint in a more effective manner, the LVLP is the better option.

Benefits Of Using HVLP Spray

1. Lower Levels Of Pollutants

The amount of overspray and pollution released will both decrease. One of its main selling features is how efficiently it transfers material, although it may need more skill than a standard spray gun.

Uneven results are a common complaint from inexperienced users. However, a professional spray gun is the way to go when working with high-viscosity paints.

2. Lessen Your Trash Output

To spray coatings, the HVLP spray cannon requires a lot of air. Afterwards, it lowers the air pressure, cutting down on overspray and other unnecessary byproducts.

Heavy coatings, such as Epoxy and Zinc Coatings, reduce help efficiency. If you want to save money on paint, investing in a decent HVLP gun (which will run you between $150 and $250) is an excellent idea.

3. It’s A Breeze To Use

The HVLP is a powerful and adaptable instrument that is also very user-friendly and inexpensive. It comes with a 1.8 mm nozzle, making it suitable for spraying various paints and stains. This pistol can spray in both horizontal and vertical lines, as well as in circles.

Pressure and flow may be adjusted for convenience. Additionally, the spray gun is simple to maintain. If you’re a professional, you’ll get your money’s worth out of an HVLP paint spray gun after only one usage.

4. The Low Velocity

Because of its modest velocity, this spray cannon is far more user-friendly than its counterparts. In any case, you’ll need extreme caution when picking the coatings you’ll spray.

Select the proper fluid and nozzle for the task at hand. Keep in mind that the HVLP spray cannon is not suitable for use with very thick or dense coatings. It’s ideal for damp, thin layers and jobs requiring uniform surfaces.

5. Convenient

To quickly and efficiently apply paint to tiny surfaces, an HVLP spray gun is a helpful tool. You may have either a compressor- or a turbine-driven type.

The hose is a standard component of spray guns powered by either a turbine or a compressor. A professional model may be purchased for a more accurate result. A more costly option is available with a longer hose.

5 Things To Consider When Buying An HVLP Spray Gun 

Here are five great suggestions to help you choose the best HVLP sprayer for your specific requirements and save money.

1. Pressure 

HVLP sprayers use pressure in a significantly different manner than traditional air sprayers.

Air pressure at the gun intake on traditional sprayers is identical to that at the air cap. At the same time that air is being forced through, paint is being forced out at very high pressure.

The typical intake pressure for HVLP sprayers is between 40 and 60 PSI. Typically, the pressure at the cap is 10 psi. The intake pressure of particular HVLP sprayers may be adjusted. Using them, you may boost the intake pressure and cap volume.

2. Capacity

How much paint your HVLP sprayer can contain is what is meant by its “capacity.” Typically, a cup is mounted above or below the cannon to store the paint.

The higher the cup volume, the fewer times you’ll need to refill it. You can achieve more even coverage in less time.

3. Cups 

The size of the cup is essential, but there are other factors to consider. The shapes of cups may vary. To begin, decide whether you like a pistol with a gravity-feed cup or one with an under-the-gun cup.

The cannon is equipped with gravity-feed cups. The paint is fed into the pistol using gravity, as the name indicates. It’s a quick and easy way to fill your paint gun.

4. The Spray Pattern And Nozzles

You might add a spray gun to your collection of tools for a specific job or general use. Your best bet is to spray guns that allow you to swap out the nozzles.

Variable nozzle guns let you adjust the spray pattern to meet your needs. This might be required for either small or huge areas.

Likewise, the paint you’re working with may dictate whether or not a specific size of the nozzle is required. Apertures should be broader for thicker paints like latex and chalk paints and smaller for thinner paints.

5. Geographical Scope

An inch per minute with a spray pistol isn’t cut when attempting to cover a large area. That’s an impossible task!

Each spray gun has a specific rating based on the amount of paint it can spray per minute or the square footage it can cover.

Listings that include “fl. oz. per minute” measure the product’s spraying capacity. Knowing this will give you a rough idea of how strong it is. However, it won’t be as helpful as knowing the CFM.

Conclusion 

Longevity and lower-pressure operation contribute to the durability of HVLP sprayers. In addition, an HVLP sprayer may be used for a wide variety of tasks. Leave your concerns about paint running and the difficulty of applying paint evenly to the past.
