HVLP Turbine vs Compressor

[jaguar36]

Looks like its been a couple of years since the last thread on this so I thought I would ask again in case there have been any developments recently.

I do all my spraying in my shop and I've always used a HVLP gun hooked up to an air compressor for spraying my finishes.  I typically use Target waterborne finishes , and have two guns from Homestead Finishes,  a QualSpray QS-600WB which I use for tinted laquers (6500/6600) and a QS-125 for clears (6000, 8000CV and 9000).  I've got the guns setup to use the Devilbliss Dekups (which as I understand is a PPS knock-off) I've been pretty happy with the setup, although I do seem to get drips from time to time.  That may be my technique, as I am far from skilled at spraying.

Yesterday my compressor kicked the bucket and when I started looking into new ones I realized I might be better off with a Turbine instead since thats basically all I need a big compressor for.  So I could go with a ~13CFM Quincy compressor for about $1000, or get a Mini-Mite 5 Platinum for about the same price.  With a compressor I could keep my current guns for now, and then upgrade them in the future as I'd like to be able to spray latex, and I would have a big compressor for anything else that might arise.  If I got the Fugi  I assume I'd be all set for spraying anything I want (correct me if I'm wrong).

Anyone have any thoughts?

Personally I'd stick with the compressor unless you want another learning curve. There have been multiple posts about turbine vs compressor and being able to spray thicker stuff like house paints especially BM Advance. The out come condensed is that you have to spend between $2000.00 and $3000.00 for a turbine rig that will be able to spray products like BM Advance as an example. $1000.00 will just get you aggravation compared to what your use to. Scott Burt along with a few others like Tom and Tim have a lot of interesting info in this regard.

Completely agree. You will have to spend more than your current estimate for a compressor for a turbine system that will spray Target 6500/6600 un-thinned, and there is a learning curve in terms of what equipment - guns, pressure pots, PPS etc. to use.

I don't know anything about Quincy compressors, what model are you looking at?

I have both systems and they both spray slightly differently but once you learn one system the other is not that difficult.
The biggest advantage of the turbine turbine/pressure pot/compressor is portability and being able to spray on location.

Where are the drips coming from the gun or drips from spraying too thick?

Well, sounds pretty straightforward then, I'll go with the compressor.

Fugi and Appollo both claim their 5 stage will spray latex well, besides for the pressure pot what else is needed?

I was looking at the Q13160VQ, 3.5 HP Single Stage, 60 Gallon, ~13CFM

Sounds like another good reason to skip the turbine.  I don't do this every day and would rather not add another variable.

They were coming from spraying it to thick.  I seem to have a hard time getting it thick enough to form a film, but thin enough to not drip.

The 4 stage can spray latex if it's thinned, but I have never found it a good experience. I sure the 5 stage will be better but probably only marginally. I can get a good coat when I spray latex, but it just seems slow going. You will need some cap sets, maybe a second gun, fluid line, 3m cups, liners, 3m adapters.

If you can afford it get the 2V41C60VC. I think those 2 stage machines are better for high CFM requirements.

What is your pressure at the gun? Do you have an air filter on your system? I use 26-28 psi. at the gun with my CA Tech. H2o when spraying 6500. Seems to atomize it better with a thinner coating.

I would stick with compressor system
The Quincy compressor are pretty good
I have the Asturo spray gun and really love it
I can spray solvent to latex with no problems
I use the 2.5mm nozzle for latex

I have no issues with my Fuji Q4. I do have a pressure pot. Pretty much spray anything with it. Don't like compressor guns.

That said looking at a AAA, not sure if I'm going with  Kremlin, C.A.T., Graco 395 or 595.

Won't get rid of the Fuji, they're great for field work.

There's really no learning curve with a turbine. And probably worth having in the even that you have to conveniently mobilize. My opinion is that my shop couldn't be without a compressor...or turbines. But thats just me.

I don't like the sound of a compressor running. To many years listening to them. My next compressor will be a rotary screw unit with a dryer.

Unfortunately, I think thats out of the price range.

Been running about 30psi at the gun, no air filter.  Most of the issue with drips comes with the clears though, not the 6500.

Probably water in the line thinning the product.
Get a filter. Should clear it up.

One turbine? Definitely a 5 stage that is easy to use, easy to store when not in use and easy to transport.

My choice is the Graco 9.5 Turboforce.

 

[junk731]

Scott just to continue the discussion a little further why would you choose the Graco over similar offerings from Fuji and Apollo.

I like the Graco because it is a 5 stage that is good both in the shop and designed for mobility with a tool box style that is good when in use, in storage or in transport.
