An HVLP paint sprayer has two chambers, one for air and one for fluid. Fluid is fed to the fluid nozzle, and the air is injected into it after it leaves the nozzle. Fluid can be fed to the HVLP spray gun by various methods, including gravity, a suction cup, or a pressure pot or pressure cup. An HVLP spray gun uses the air to effectively break up a coating.
The benefit of using air is that it provides a fine breakup, resulting in a high-quality finish. Additionally, the HVLP spray gun uses low-pressure air, which allows for a very high transfer efficiency of the spray gun.
Transfer efficiency references how much of a coating is applied to a product surface versus how much ends up not being applied and becoming overspray. While HVLP uses Low Pressure, it requires a High Volume of Air. It needs a compressor that supports a large CFM of air to feed the spray gun. You will have to use a turbine HVLP Spray Gun unit, which you can learn more about here.
What is an Airless Paint Sprayer?
An airless paint sprayer uses fluid Pressure and a small opening to cause fluid to be atomized. Unlike an HVLP spray gun, an airless paint sprayer does not use air to help break apart a coating. Since air is not used in atomizing the coating, an airless paint sprayer will not provide the same finish quality as an HVLP spray gun.
However, since an airless paint sprayer uses a piston pump, it will most often provide a higher volume than an HVLP spray gun. Additionally, Airless Paint Sprayers are offered in electric and gas-driven models, which can help when portability is critical.
When is an HVLP spraying Gun the Right Option?
An HVLP spray gun will typically be best when your primary goal is the quality finish you are applying rather than the speed at which you apply a coating. An HVLP spray gun is also ideal when you want to minimize the amount of coating you use. This can be important because it can be a requirement depending on the industry in which you work as well as the state in which you work. You can find out more by contacting your state EPA.
Another scenario where an HVLP spray gun will be ideal is when you do not need a large volume of paint for your particular product or project. If you only need a small amount of paint, you can use a gravity-fed, suction cup-fed, or small two-quart pressure cup, which will keep your waist to a minimum and keep your coating costs down.
You can review this resource to learn more about each method of feeding a spray gun. If your coatings are highly viscous (thick), an HVLP spray gun will not be a good option for your coding application need. This is because an HVLP spray gun is limited in atomizing heavy coatings.
When is an Airless Outfit the Right Option?
An airless paint sprayer will provide higher production and higher pressure. The higher production and higher pressure that an airless provides makes it an ideal scenario for covering large areas with paint where finish quality is not a huge concern.
Additionally, if you have to provide fluid over very long distances because you’ll be painting at high heights far away from your paint equipment, an airless allows the paint to be fed effectively.
The high pressure that an airless provides makes it ideal for highly viscous coatings like zinc-based coatings, latex, epoxies, and roof coatings. The downside to airless is that it is only about half as efficient at applying a coating to a surface compared to an HVLP spray gun.
Ideal Airless Applications
Painting large areas like bridges, steel, and new construction
Applying thick coatings
Residential painting with latex
Construction work in the Field
Hvlp Spray Gun Ideal Applications
Wood Surface Coating Application
Industries that require HVLP for Emissions Reduction
Touch-up repair work
By choosing the right application equipment, you can ensure a smooth painting experience. Choosing the proper equipment based on the viscosity of coatings you will spray, the production you need to achieve, and the environment you will be spraying in.
