Looking for a new spray gun
 
Have been suing a Harbor Freight "purple" HVLP gun but am looking to get something better. It has done "okay" but not great in my opinion. I know many woodworkers go with a turbine, but since I have a good air compressor setup (7 HP/60 gal tank) with filters and such, why spend the extra $$$ on a turbine when I can just get a good conversion HVLP gun. I also don't see the need for portability that a turbine offers. I am leaning towards the DeVilbiss FLG4 gun (the FLG671 kit more specifically). I know this is mainly used for automotive, but it also seems to have high marks for woodworking. I am not opposed to a turbine I suppose, but for most of what I spray (which isn't latex, but mostly WB acrylic and lacquer) I just don't see the need. Anyway, thanks for any input.

The best gun for you may be more than one gun. If you want to use a product that is rated excellent for a full line of finished you will probably have to get a gun whose characteristics most nearly fit the need.

The DeBilbess line of guns may be the best overall for spraying relative thin finished like automotive finished. I do not know the exact model you reference, but the that line of guns is outstanding.

I have the HF purple gun and I don't care for it either. I bought it and mainly use it for catalyzed finishes. Since the gun is gravity feed I'm able to use every drop. The gun just takes too much attention to keep it spraying right so I don't use it any more than I can help. The gun I do like is HF #97855 siphon sprayer. I have four of them so I can use one for stain, one for paint and two for clear finishes. They work fine for wood finishes. If I were mainly painting cars then I would be inclined to purchase a Devilbiss sprayer.

I bought a devilbiss hvlp gravity finish line model couple years ago, with the disposable (dekups) cup system. nice.


think I saw one now where the only clean up is a couple of internal plastic pieces. to me, as long as I can get a decent finish, it is all about the cleanup time, and solvents costs. (gone water base only now)

About the DeVilbiss FLG4 (which is a Finish Line model), the specs say it needs 13 CFM @ 23 psi. My compressor is rated at 11.3 SCFM @ 40 and 10.8 SCFM @ 90 psi which is technically under-rated. What are your compressor specs? Now I won't be spraying a car so don't need long-term flow, but wonder if this will be okay. I will be spraying the typical wood piece...tables, cabinets, etc. On one website I think they say for woodworking you can use it with as small as a 1-1/2HP compressor, but that seems to go against the mfg specs. I guess I could contact DeVilbiss for something definitive.

A lot would depend on the size of the area you will be spraying and a table top needs as much long term flow as painting a car. Once you start spraying a table top you are only covering about 4" to the stroke so if you have a table top just six feet long that's 18 to 20 passes with the sprayer. If the compressor can't keep up you might find yourself three fourths of the way across the table top and have to stop and let the compressor catch up. You just can't start and stop when spraying an area. It will leave a mark where you start and stop. You might find a solution by adding an additional tank to the system. This would give you more time before the pressure drops too low. Sometimes you can find an old compressor cheap on craigslist that needs work but the tank is alright. At 40 psi I've also used an old propane bottle for more volume. You just have to get a left hand thread adapter to connect the plumbing.

A compressor rated at 11.3 SCFM @ 40psi should be awful close to 13SCFM @ 23psi. I think you will be Ok.

I use a DeVilbiss Compact Mini for lacquer and shellac. Uses about 4 CFM @ 20 PSI.

Another one I have found, but cannot find a whole lot about, is the Astro EUROHV107 (1.7mm tip). Says it needs 9-10 CFM which is just a bit under of what my compressor puts out. I am also unsure of the tip size I should get...thinking 1.5mm or 1.7mm seems about right. This one seems to only come with one tip and cannot find just the tips (maybe that's a bad sign already). Planning to shoot WB acrylic, lacquer and maybe shellac. I might use it for other stuff later, but that is my current and foreseeable future.

16cfm @175psi, 5hp 2 stage 60 gal. but I really don't think you will have an issue. our flg kit came with 1.3, 1.5 & 1.8. but we almost ever use anything but the 1.5 on wb lacquers and stains (target coatings). I put a small regulator/gauge unit on the gun input so we could control the pressure at the gun. maybe the flg4 needs more air??

For the Price the Devilbiss FLG 4 is a great choice. With your compressor it should work out fairly well. This article highlights options about wood finish spray guns
