1) LVLP uses a lower volume of air to atomize the paint at the cap.
LVLP compensates for the lack of air with a precision air cap that acts like a bunch of tiny sharpe knifes that cuts your material. By using a lower volume of air, it means you can operate your LVLP gun with less CFM and a smaller compressor, usually about 3-4CFM less than HVLP. (Note: Reduced Pressure,HTE, CG,Plus or reduced pressure guns also use less inlet CFM than HVLP, usually about 1-2CFM less than HVLP - It seem un-intuitive, but it is a matter of engineering design). Therefore, you can operate either LVLP or Reduced Pressure HTE guns typically with a smaller air compressor than standard HVLP guns
- 2-3 hp is still recommended, but 1 1/2 can get you by.
Note: In ranking both LVLP and LVLP Style HVLP and Reduced Pressure Transtech HTE guns with their super fast speed both out spray most standard HVLP guns consuming 10-15CFM. However, assuming you get top of the line equipment, in true world tests, you will not be able to tell the difference in finish quality with the top LVLP guns we have at spraygunworld.com, RP Transtech HTE and HVLP Guns. Inotherwords, LVLP Guns are amazingly professional, spray an amazing finish while using little air, have the highest material savings of all guns (even
better than HVLP gun) and provide good control. The only real down side to LVLP is its slight reduction in spraying speed. *Note: Woodworkers without a booth, with a smaller compressor and who take their time spraying may like the low overspray of LVLP.
an HVLP or LVLP? Today, HVLP is most common spray gun on the market. HVLP has a very long track record and good guns have become available at lower prices.
In favor of LVLP, LVLP has
a softer spray with the lowest overspray levels on the market, and assuming LVLP guns are maintained well, they are a joy to work
with. Also, for auto painters with small compressors, LVLP give you another option besides Low air HVLP or Reduced Pressure (reduced
pressure guns) to paint an entire car nonstop. LVLP are also great for mobile workers who spray outdoors or in car lots. For woodworkers and LVLP allows you to get a professional result with very small compressors even under 6CFM@40psi. And those spraying on location or inside your own home, will appreciate the lower overspray levels. LVLP guns and HVLP guns based on LVLP technology have the least amount of overspray or all guns on the market. The 5%-10% in higher transfer efficiency over HVLP and as much as 15% over Transtech HTE make LVLP a top choice for those where overspray might be an issue.

4) What about Reduced Pressure, HTE, CG, Transtech, and PLUS? In a large shop environment where speed is the most important factor, we prefer Reduced Pressure, HTE style guns for wood, boat, plane, industrial and even auto. Many of our guns are now convertible to switch between technologies. Reduced Pressure guns have the benefit of operating with a relatively small compressor and provide arguably a better finish quality over HVLP. Having the fastest working speed of all the technologies mentioned, is also an important factor for a professional - but maybe not as important for a smaller production level or serious hobbyist who might like the slower more artist controlled spray of an LVLP gun.
In the end, however, when you purchase any professional gun from our site the differences are slight. So do not be overly concerned about which technology you go with or ask us your questions. Since we only carry the best spray guns on the market, you will be happy with your choice.
