I need to get to the nut and bolts for a conversion spray gun. I have also rev. all the post and they have not answered my questions. Much talk about a five-hp compressor being just fine. What is the 5 hp driving, two cylinders or four, one cycle system or two? To me horsepower does not answer the question. CFM would seem to be more relevant in matching a spray gun to a compressor. Now to the practical aspects, Quincy compressor, single stage, 20-gallon tank, CFM @40 is reported to be 8.1. What conversion HVLP spray gun will work without excessive draw down of the tank and not require spending $500 or buying a gun that will reuiore all day to spray a cabnet? I have looked at a Sharp, requires 7.5 @ 50, is this too much air demand for the Quincy? Dealer says it will work off a 3-hp motor. Many commercial air compressors run of 3-hp, but drive four cylinders for high output and quick recovery, of course I will not be able to recover the added cost for such a unit. I would appreciate some factual help, spray gun to compressor CFM. Thanks for your help.

Go by the CFM before anything else. Your 8.1 CFM at 40 PSI will drive a Sharpe 998HVLP gun just fine for most spraying. Your compressor probably has a 50% or 60% duty cycle, and it's pretty hard to spray more than 30 minutes out of an hour in non-production usage.
I have a Sharpe HVLP gun as well as several conventional guns, and a similar sized compressor, and it works just fine.
*Steven, I have been using a Binks model Mach 1 hvlp off of my home compressor Which is a Sears model with a 12 gallon tank. I use two of these guns in my production enviornment off a 100 gallon tank and i find no difference in the way they operate in lieu of cfm. However, The two i have in my production environment are set up strictly for pressure whith different internal parts but regulate the same. The one i have at home is set up for air atomization and has a cheater valve attached and works a little different but maintains the volume i need consistantly for what i am doing wether it be large or small projects. Talk with your local dealer and i am sure they will tell you the same.Devillbis makes a simillar gun that i was fortunate enough to test and works just as well at a little less in cost but i like the feel of the Binks model better. You may also consider an Appolo gun which are very user friendly and maintain the cfm you are requireing. You can reach them here on the web at http://www.appolosprayers.com. GOOD LUCK..
*I'm navigating uncharted waters as far as I'm concerned. I likely have too many questions for you to answer, but here's a few.I need a recommendation for a conversion HVLP gun and compressor. I'm starting from scratch, and as a result am not wedded to any particular brand or style. I can tell you that I believe that I will be spraying water based poly over dye on kitchen tables.By the way, feel free to disabuse me of the notion that the water based poly (I will not be building a spray booth) over a dye may be the best surface for cherry kitchen tables.I noticed the Apollo brand on the net as well. Are there any recommendations you can give regarding same? Particularly in light of the fact that Las Vegas does not have a distributor? Thanks in advance for your help. G.
