I appreciate all of the comments I received in my recent thread; “Finishing Systems – HVLP and AAA”.
Not to discount anyones advise or offend anyone there comes a point where you simply have to make choices.
After Much Thought and Discussions with people on a lot of different forums I am moving in the direction of an HVLP/Compressor spraying system for my furniture shop.
I’ve dropped my aspiration of finding a “one size meets all needs solution”, which is not an uncommon first step to take when starting out learning about something new and decided on a best long term solution for my most frequent finishing needs.
I looked at the convenience of an HVLP turbine and decided that it would be limiting in terms of the range of what it can do based upon input from a lot of users of those systems.
I decided if I need to paint walls of ceilings I will rent something such as an airless of I want to try it out.
I decided that AAA is best for production environments which I will never be.
Since I also could use a better compressor than my current portable CH (so noisy I can’t stand being in the same room with it) and based upon comments of flexibility and cost that spray guns are the way to go. I am thinking HVLP guns at this point to lessen over-spray and improve transfer.
I realize that the learning curve for compressor spraying is likely steeper for than for turbine HVLP but my goal is long term, not short term.
The direction I am heading is buying the following:
A. Ingersoll Rand compressor seem to be priced well and comments give good indications of long service life. As I don’t want to buy twice, I would like one that will do what I need now, and could need to do in the future as well. So I am narrowing it down to one of the following;
1. Type-30 Two Stage Reciprocating Air Compressor — 60 gall. 14 cfm. at 175 psi, 5 HP, 230 Volt 1 Phase, Model# 2340L5-V – $1,200.00
2. Ingersoll Rand Two Stage Type-30 Reciprocating Air Compressor — 5 HP, 80 Gall, 14 cfm. at 175 psi, 230 Volt Single Phase, Model# 2340N5-V – $1,399.00
or
3. Ingersoll Rand Electric Stationary Air Compressor — 60 gall, 18 cfm. @ 135 psi, . 5 HP, 21 cfm. @ 40 psi, 18.1 CFM @ 90 PSI, 230 Volt, Model# SS5L5.
B. Filter Separator – CAMAIR QC3 filter/coalescing filter/regulator – $175.00.
C. Goodyear Rubber Air Hose — 1/2in. x 50ft., 300 PSI $60.00
D. CA Technologies – Saber SS SLP HVLP/ 1 Qt. pressure pot with .8, 1.2, 1.3, 1.4, 1.7 needle sets. $450.00.
E. Allegro Safety Half Mask Supplied Air Respirator System-One Man $700.00 seems like a more comfortable alternative to the restrictive half face masks.
F. Two ZipWall® [4PL] 4-Pack Plus Dust Barrier Temporary Wall System $440.00. To keep it all contained. Should be safe as I intend to limit my finishes to water based,
What I am questioning at this point is my compressor choices. It’s a bit confusing and I don’t know how to interpret the face plate data on these units. The double stage 2340L5-V and 2340N5-V CFM ratings don’t change much from higher to lower pressure ratings; whereas the single stage SS5L5 gets significantly higher cfm at lower pressure values. I thought higher cfm equated to being able to spray with a wider range of guns. I do understand that larger tanks sizes result in less compressor cycling.
Comments or observations are appreciated.

Compressor
a 30 gallon - 2 stage IR 230 volt is probably enough -
I like using a light thin flexible hose instead of heavy rubber - you don't feel like you're being pulled by the hose when you have a spray gun or nail gun attached.
You need a galvanized pipe system tilted back toward the compresser - and a good extractor at the gun station -

Agreed, this systems allows for light thin flexible hose the last "so many feet" from the pot to the gun.
Your compressor systems seem extremely large for one person using an HVLP gun, unless you will be spraying continuously for 10-15 min. Your hose, flexible or not, I think should be no smaller than 3/8".
I've always found Jeff Jewitt very fair with his suggestions, and I really like being able to get so much of my spraying equipment and materials from the same one source. His web site is http://www.homesteadfinishingproducts.com and recently he released a very good book and dvd on spraying. Just my opinion.
