I've never worked with a 2.0 tip but I put out an email to someone who knows much more than I about spray equipment and is very familiar with CS. Should have an answer later this eve
Thanks for the order!
I would imagine someone would make it in a HVLP But have not seen one in an inexpensive model (Yet)
But this one we are talking about is LVLP reading up on this seems interesting (Sorry kind of long)
"Want HVLP performance, but with less air requirements? and even lower overspray levels? Welcome to LVLP.
LVLP is great for painters who want all the benefits of HVLP but with less air requirements. Automotive or Wood painters who do not have a large air compressor will now be able to achieve a professional finish and paint an entire car or very large surfaces "HVLP Style" without stopping. You can get away with an inexpensive 110v compressors from Sears and the like, 7CFM@40 (or even less for wood 5 CFM@40). LVLP is also good for mobile painters due to the smaller air requirements and low overspray (discussed below).
Note: for woodworkers, pausing is not as big an issue and compressor size is less important UNTIL you fall under the 7CFM@40 mark, then LVLP guns are a great alternative to Low Air HVLP guns or Reduced Pressure Guns. (On a side note: for 6CFM-8CFM we also recommend looking at Reduced Pressure HTE (RP-HTE) guns, especially for people who are used to traditional conventional equipment, or those who like or need a fast working speed. Devilibss Plus or any of our European Guns with HTE Technology are terrific Reduced Pressure and a top choice for wood workers.) Over 8CFM and you can use most any technology you wish, You can comfortably use some of the full sized, more power hungry HVLP guns.
The second benefit of LVLP is the low overspray levels. The designation for LVLP is Low Volume, LOW Pressure. An LVLP Spray Gun can operate at less than 10 psi at the nozzle cap as compared to HVLP which operates at 10 psi at the air cap and is usually pushed higher by the user for better atomization. LVLP has a transfer efficiency well over 70%-80% (5% higher than HVLPs) of putting the paint onto the surface being coated. This means very little overspray will be produced, saving on paint cost and environmental hazards.
The major drawbacks of LVLP guns are a slight reduction in speed (see RP HTE guns to solve this problem) and a little reduction in fan pattern width (typically maxing out at 10"-11" - not an issue for most woodworkers).
What this means to you...
What is LVLP?
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.
3) Why 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 our estimation the 5% in higher transfer efficiency of LVLP is not a discernible difference for most users and should not be a concern unless overspray is the most important factor to you. In general then, we can recommend either HVLP or LVLP for most applications. While we recommend HVLP over LVLP for a professional with a large 220v compressor due to the increase in speed, smaller shops, woodworkers and / or serious hobbyist we recommend either with complete confidence.
In favor of HVLP, some argue that so little air is used to atomize the paint of an LVLP gun, (remember, it is the air that breaks up the paint) that an LVLP gun must be maintained in great condition, otherwise they tend to be finicky and any imperfections in the gun will affect your atomization quality. So if you are lazy and don't clean your equipment, or if you spray in a particularly dirty environment or have contaminants after long spraying time, LVLP may be more difficult to keep clean. Also, some argue that LVLP has harder edges and therefore is not good at blending as HVLP (while others like the harder edges as it is more precise and easier to control for definition). In addition, LVLP tend to spray slightly slower than many HVLP guns and definitely slower than Reduced Pressure guns.
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.

so if the larger tip is Ok this could sound like an interesting choice, the low over spray and all would be nice working on the car (yes not as critical underneath But in other spots could be a plus) ?
I appreciate your trying to find something out, will watch for a reply!
