HVLP is an acronym for High Volume Low Pressure which means a high volume of air at a low air pressure. Atomization is achieved by the volume of air not by high air pressure which reduces the forward velocity, thus creating a softer spray.
What is the difference between HVLP and airless sprayers?
In an HVLP (which stands for “high volume, low pressure”), air pumped from an air compressor or turbine atomizes paint. In an airless sprayer, a piston pressurizes the material, which sprays out of an orifice smaller than that found on an HVLP nozzle. The high pressure and tight squeeze shear the paint into particles.
What is HVLP spray gun used for?
With the hardworking contractor in mind, HVLP paint sprayers (sometimes called turbo-sprayers) are professional paint-spraying equipment ideal for use on trim, finish work, furniture staining, cabinet painting, and any detailed applications where high-accuracy, speed, and a smooth finish are needed.
Are HVLP spray guns any good?
Unlike airless sprayers, most HVLP sprayers in this price range can’t shoot unthinned latex paint. However, they have a few advantages that we think make them worth considering. First, they’re quieter and the noise they make is less annoying—more like a vacuum cleaner.
Is HVLP better than spray?
They are about twice as efficient as Conventional Spray Guns applying about 65% of your material to the target. However, a high quality HVLP Spray gun will usually cost more than a conventional gun (anywhere from 150 – 250 dollars more).
Are HVLP sprayers worth it?
High Volume/Low Pressure (HVLP) Pros: Good for interior use since low pressure (3 to 10 psi) creates little overspray and a very smooth finish; mid-range cost ($200 to $500 for better home-use models). Cons: Can’t spray thick paint. Best for: Finishing inside trim, cabinets, moldings, and doors.
What are the advantages and disadvantages of HVLP spray gun?
Advantages: Higher transfer efficiency than air spray guns. Disadvantages: Not compatible with high-viscosity fluids. Slow for painting. High-volume, low-pressure (HVLP) spray guns were developed to avoid the problem of overspray encountered when using air spray guns.
What is better HVLP or LVLP?
What is the difference between HVLP or LVLP spray systems? HVLP guns use more CFM and will require users to size their air compressor accordingly. On the other hand, LVLP atomizes better, sprays faster and lays down a better finish while using less CFM but high air pressure.
Can you spray latex paint with an HVLP sprayer?
HVLP systems are not designed to spray heavier bodied latex paint. The pressurized cup allows the paint to be pushed to the fluid nozzle because of the added pressure behind the paint. If you look at most professional airless paint sprayers designed for latex paint, they are actually pumps, and use no air.
How do I buy a HVLP sprayer?
5 Things to Consider When Buying an HVLP Spray Gun for DIY Pressure. The major difference between HVLP sprayers and conventional air sprayers is the way pressure is used. Capacity. The capacity of your HVLP sprayer refers to the amount of paint your sprayer can hold. Cups. Nozzles and Spray Pattern. Area Covered.
What size air compressor do I need for HVLP?

Can you use HVLP to paint a house?
A HVLP system is great for spraying a variety of house paints, primers and clear wood finishes. The end result is difficult to duplicate with other equipment or manual application. Begin by spending some time stirring and thinning the product to be sprayed.
Can you use a HVLP gun with an air compressor?
Air Can be fed to an HVLP Spray Gun via a turbine unit which uses a series of fans to provide high volumes of air at low pressure to the spray gun. It can also be fed by a traditional air compressor .
How much pressure does a HVLP gun need?
HVLP, or High-Volume/Low Pressure, uses a high volume of air (typically between 15-26 CFM) delivered at low pressure (10 PSI or less at the air cap) to atomize paint into a soft, low-velocity pattern of particles. In most cases, less than 10 psi is needed in order to atomize.
Are gravity feed spray guns better?
Summary. In most cases, a gravity feed paint spray gun is the better choice thanks to its efficient and versatile design. Although HVLP is a requirement in most areas, whether or not you use an HVLP gun, gravity feed offers the advantage over conventional feed because of the lower air pressure requirement.
How do you thin a water based paint for a spray gun?
When thinning your water-based or latex paints, use half a cup of water and mix thoroughly. If you have added too much water and the paint just runs out, it is too thin, and you will not be able to use this. You will need to slowly add some paint into your paint bucket, start with half a cup of paint.
Which type of spray gun uses the most paint?
Pneumatic Air Sprayer However, compressed air sprayers are messy and emit more overspray than others. They also use the most paint, but the sprayers themselves cost much less than airless or HVLP sprayers.
How do you thin oil based paint for a HVLP spray gun?
Steps for Thinning Oil Based Paint for Your Sprayer Pour the paint through a strainer into a clean container. Add 1 part mineral spirits or turpentine for every 3 parts paint. Stir paint with a clean stir stick until the thinner and the paint are fully mixed. Run the thinned paint through a funnel.
What kind of paint do you use in HVLP?
HVLP paint sprayers work with oil-based paint, but thicker paints such as water-based latex can clog the sprayer. Combine a half cup of water for every gallon of latex paint in a bucket and stir thoroughly to thin its consistency before using latex paint an HVLP gun.
What HVLP should I buy?
BEST OVERALL: Wagner Spraytech Control Spray Max HVLP Sprayer. BEST BANG FOR THE BUCK: NEU MASTER 600 Watt High Power HVLP Paint Spray Gun. BEST COMPACT: REXBETI Ultimate-750 Paint Sprayer, High Power HVLP. BEST PRO: Master Pro 44 Series High Performance HVLP Spray Gun.
Do HVLP paint sprayers need an air compressor?
The most common air paint spray guns use a “high volume, low pressure” (HVLP) delivery mechanism, so you need a spray paint compressor that delivers the necessary pressure and volume of air to achieve a perfect paint flow.
Are electric paint spray guns any good?
While other spray methods vary, laboratory tests have repeatedly shown that airless is by far the most efficient. Without air blowing the finish hither and yon, a very high percentage of coating ends up on the wood. In terms of volume, airless guns move finish much more quickly than any other type of spray gun.
