What is spray gun painting? Spray Gun Painting uses air to directly atomize and direct paint particles onto a surface. This paint gun or device sprays a coating of paint, ink, varnish lacquers etc. through a front orifice which is sized to match the viscosity of the material. i.e. the thicker the material the larger the exit or fluid nozzle or orifice. As apposed to brushes or other techniques, spray gun painting produces a flat superior flawless finish. It is not difficult to get a glass like finish. It really depends on how good your spray gun is. In otherwords, by investing in good equipment anyone can produce a flawless finish. As opposed to aerosol paint cans which are too expensive. There is not enough power in an aerosol can to truly atomize the paint as well as a "true spray gun".


HVLP is one of the most common and well supported technologies around. Many of the new literature and training techniques will use HVLP in their examples.

HVLP spray guns are designed to improve transfer efficiency. HVLP guns push paint particles at about half the velocity of conventional spray guns. While this means you have to spray closer to the surface, you gain by having your material actually get applied to the object instead of floating into the air.

The spray gun itself requires a lower pressure to atomize the paint i.e. (LP) by using a higher volume of air (HV) to atomize and propel the paint. The result is a higher volume of material hits the surface which reduces material consumption and air pollution. A general idea is that it takes two thirds of the coating on the substrate and one third into the air i.e. 65% or Greater transfer efficiency as mandated by the government for HVLP markings. Typically this means you need to use 8-20cfm to atomize the paint correctly with a min of a true 3 HP or 5HP peak motor. Luckily, we carry the low CFM gun models which consume from 3-8CFM that produce equal or even superior finishes to higher CFM gun models. Why? because it is more the design of the gun and the precise manufacturing techniques not the size of the air that matters. Please ask us at

Does this mean there is no overspray? No, compressed air exiting the gun still pushes back and pushes solids away from the object being sprayed, just a lot less. It is estimated by the US EPA that typical material savings can well exceed 50% which is money in your pocket.

Traditionally, HVLP guns use more compressed air than conventional air spray guns, which means increased energy costs. Today however, HVLP guns use less cfm of compressed air than older HVLP guns and we currently carry the only "Green" Spray guns which consume 50% less power then their competitors, can operate on 110v compressors and yet deliver the same quality of finish.

HVLP guns due to their softer spray are great for applications where the operator needs a high degree of control at the gun

Turbine HVLP

Turbine HVLP uses vacuum cleaner type fans in a a box to generate air power. The number fans determine the "stages" of the turbine. 3 is a very minimum for a professional and 4 stages are a preferred level in order to achieve the similar quality of a true compressor driven HVLP gun. In the end however, compressor guns have more power. So why use a turbine? Portability and they run easily on a 110v compressor.

Other factors such as heating the air and air cleaning are red herrings. They key is how you will use the spray gun in your work environment. As an alternative Low CFM spray guns can be run on a 4 gallon 2HP compressor.



Same as HVLP




A little less power than compressor driven HVLP.

To compensate with the lower power it requires a good gun like the top brands that we showcase our site. i.e. Cheap and inexpensive turbines will not produce a good finish.
