Hello, John. I can't thank you enough, for your valued response. Your advice and expertice, was just what I was searching to find. None of the reps,nor the guys, that do this for a living, provided me with the right answers. YOU did !! Thanks to you, I've now got the info I need. The multi stage turbines, offer little to no thinning, less multipal, repeated coatings, so they finish much faster. Now they can proceed to their next job,more quickly.

Hello, John. I can't thank you enough, for your valued response. Your advice and expertice, was just what I was searching to find. None of the reps,nor the guys, that do this for a living, provided me with the right answers. YOU did !! Thanks to you, I've now got the info I need. The multi stage turbines, offer little to no thinning, less multipal, repeated coatings, so they finish much faster. Now they can proceed to their next job,more quickly. Less thinning, means a better, higher quality finishing job, because of less dillution to the coating and providing lower VOCs. You CAN work with smaller turbines; It's not impossable, like I was led to believe. Now for my point of view. I've conducted much research, concerning hvlp systems. Here's my advise.Fuji, Appollo, Turbineair along with others, are considered "turbine in a box". Stay clear of those. Why? Again, we arrive at the heat problem. If you can't get rid of the heat, the life of any turbine gets cut short. From my research the only two turbines, that get rid of the heat correctly are Titan and Graco. I prefer the Titan; that's just me,tho. The Titan's a monster, well constructed, has all the "creatures features", is small enough to fit anywhere in my truck, has an onboard tool box, and a built in cup holder, and at 20lbs.,fits my needs. It also has dual air filtration,providing better longgivity to the turbine, and no "heat up the hose". If you purchase it from a SherwinWilliams dealer, Titan offers a FREE spray gun, in addition to the one it comes with. That gun's not a toy. The gun's about $250.00, or so. For me, I can use one for primer, the other for finish. I think the free gun offer expiries this June. When in June, I don't know. Again, please, thank you so very much for your kind response to my question. This typing is killin me !! Gotta go for now. I'm sure others have also benafitted from your information.

<p>Hi Dave - I've sprayed Behr Ultra Premium Plus gloss paint to finish up some trim when I painted the house last summer. I did most of the house with a Spraytech airless but had a few feet of trim around one porch to finis so I thought I'd try it.</p>
<p>I did have to thin it quite a bit. I was at about 5% or so with Floetrol for the airless so I added some more floetrol and then bottled water until I got good atomization. May have been up around 20% + diluted. That thin I did have to go back…</p>

<p>I did have to thin it quite a bit. I was at about 5% or so with Floetrol for the airless so I added some more floetrol and then bottled water until I got good atomization. May have been up around 20% + diluted. That thin I did have to go back over it several times, maybe 5 or 6 but ended up with a very nice finish. Rather than risk runs, I just sprayed it on and if it covered OK, if not, OK too. When I got to the end I just went back and did it again. Small area, about 30 ft of window sills and trim, It flashed off and was ready for recoat in about 5 minutes so recoating wasn't a big deal. I think I will be planning an upgrade to the unit though, definitely not up into the $1000 - $1500 range, way to rich for my blood.</p>
<p>I've heard a lot of good things about the Fuji Mini-Mite, 3 stage for $550 or so.<br/><br/><cite>DAVID CZUPRYN said:</cite></p>

<p>I really hadn't thought about the exhaust heat of the turbines before. Just one point though. Multi stage systems tend to be pretty pricey, far out of my budget at the moment. I have found with latex paints though is, while not ignoring the mfg instructions on the can completely, exceeding the recommended thinning until I could get an acceptable spray worked pretty well. It did take several more coats, but they could be applied almost immediately. I usually thin with Floetrol, not to exceed 10% and if more thinning is needed, bottled water. More than 10% Floetrol will affect the sheen.</p>
<p>Now, what excessive thinning will do with oil based products, I have no idea.<br/><br/><cite>DAVID CZUPRYN said:</cite></p>

I've downloaded manufactures manuals and most of them suggest using a slow thinner,and a paint additive {to slow the drying time} to attempt to compensate for this heated air. Where does the hose attatch to the gun? At the bottom of the handle, or the back of the gun? In this case, the back of the gun. Why? It's trying to get the all the power the turbine can generate to atomise and break up the coating. This set-up, may change the gun to a bleeder type. This configuration is usually used to spray very heavilly viscosity coatings,such as multispec. I'm open to any comments, that anyone else would care to share with the rest of the community.

<p>Hey Will, </p>
<p> </p>
<p>Okay I have had a look at the Earlex 5500 and it looks fine. The needles are all dependent on what material you are spraying. Basically if you think about it, the thinker the material and the smaller the needle the more pressure you will need to get it to atomize out of the gun. Now if you are not atomizing (making the material into a fine mist) well you will start to get a orange peel effect on your finish. You really really don't want that. You can fix anything…</p>

<p>Okay I have had a look at the Earlex 5500 and it looks fine. The needles are all dependent on what material you are spraying. Basically if you think about it, the thinker the material and the smaller the needle the more pressure you will need to get it to atomize out of the gun. Now if you are not atomizing (making the material into a fine mist) well you will start to get a orange peel effect on your finish. You really really don't want that. You can fix anything besides paint runs and orange peel effect when the material dries on too thick.</p>
<p> </p>
<p>The smaller the needle to more viscose the material. I would suggest that you get a 1.5mm needle. It is a bit of a all rounder needle. I only use that. What I would really suggest is a viscosity cup. It takes all the guess work out of everything. You will see at the bottom of this link <a href="http://www.earlex.com/hv5500-accessories.php" target="_blank">http://www.earlex.com/hv5500-accessories.php</a> they have all the run times. So what you do is thin the material according to the manufactures specs. Be sure to use the thinning material that is recommended ONLY. Otherwise you get all sorts of issues like waxy build ups, runs, material that will not dry and and and. If you have thinned your material down to the manufactures specs and the viscosity drip test checks out you will be good to go.</p>
<p> </p>
<p>You know how to spray? Pattern settings, air flow, movement across the surface and over spray etc?</p>

<p>HVLP: 14-43 PSI; 4.2-7.1 CFM</p>
<p> </p>
<p>CFM (cubic feet per minute) is the main aspect that you are dealing with. The pressure (PSI) is pretty much low enough for all compressors to handle. The CFM is how fast the tank is going to consumed. Now you will see that if your compressor can not maintain a flow of 7.1 cfm you are going to have your compressor cycle and try compress to pressure again. Now compressors also have a duty cycle. E.G. 60% duty means that out of a 10 minute cycle it will have to "rest" for 4 minutes. Now this can be a problem if you are busy with a job and you run out of air half way through a panel. You will be able to spray with a smaller tank but you are going to have to stop start a lot.</p>
<p> </p>
<p>So in summary you want to have a look at the gun you are using and check out the CFM and at least double it if you want to spray constantly. The bigger the tank the longer the store which helps with the duty cycle. V-Belt driven compressors are quieter and last longer they say. </p>
<p> </p>
<p>Hope that helps.</p>
