Question: What Is A Hvlp Sprayer

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.

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 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.

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?

HVLP guns require plenty of air, so you need to have a larger capacity compressor higher than those used for diy home works. In order to spray the full range of finishing products, however, you need at least a 21⁄2 to 3 HP compressor with a 75 liters (20 gallons) tank.

Do you have to thin paint for a HVLP sprayer?

Quality latex paint is significantly thicker than traditional finishes and must be thinned before it is useful as a spray finish. Insufficient thinning results in the paint coming out of the spray gun in unsightly blobs or not at all. Thin the paint with water and mix well before spraying.

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 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.

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.

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.

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 .

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 big of an air compressor do I need for a LVLP spray gun?

What Size Air Compressor Do I Need for a Spray Gun? Sprayer CFMs DeVilbiss 12-13 Iwata LVLP 16 TCP Global Kit 3.5-7.1.

Why does my HVLP gun sputter?

Spray guns spit when air is being introduced into the fluid outside of at the air cap. A loose fluid nozzle does not properly seat in the tip of the spray gun and causes air to enter the fluid supply resulting in spitting.

What psi do you use to paint a car?

Look for a minimum of 15 psi, with some applications, such as clear coat, better-suited to 20 or 25 psi. Horsepower: For auto painting, a 10hp compressor will typically suffice. However, higher horsepower compressors may operate more efficiently, and can be used for other tasks.

Can I spray house paint with HVLP gun?

Spraying any clear finish or paint with an hvlp or cup gun can be a little tricky, but with practice using this type of paint spaying equipment will become easy. A HVLP system is great for spraying a variety of house paints, primers and clear wood finishes.

Can we use a HVLP sprayer on the exterior of the house?
