These guns claim to only needs 1.5cfm at 30 psi. Everything else I’ve seen that looks remotely like them requires 10X that flow. I asked one of the guys at the store if it was correct or whether it was a typo. He said no not a typo. Regardless I couldnt pull the trigger (pun intended) on buying one until asking some of the experts here who may have actually used/owned one

I have one of those loud little 6 gallon pancake compressors by porter cable. It has served me well over the years and until I can afford a larger compressor I wanted to see if there was anything out there I could use to spray water based polys.

thanks in advance.

I’ve never been too happy with siphon feed guns. Gravity or pressure feed work a lot better.

I’d suggest looking into LVLP gravity feed guns.

+10 for gravity. I use the HF hvlp gravity feed guns, which ever is on sale. I bet the numbers are true at 30 psi. The thing is that at 30 psi you might be able to spray water. With the ones I use I usually end up somewhere around 55-75 psi. I know that is way more than recommended, but that is where I need the pressure to be in order to atomize the thinned latex paint. When I spray poly of stain I use less to keep the over spray down. thier guns are a great buy, but you have to have a real compressor to use them. If you are spraying small projects you may be able to get buy with a small compressor.

I have a Campbell-Hausfield sprayer similar in size and design to unit in the second link you posted, and I also have the very same compressor you mention. I have no trouble using the two together. I have sprayed lots of shellac, and also some thinned latex paint without any trouble.

The problem with spraying latex at high pressure is: it causes the water component to separate out from the paint causing the solids to be deposited unevenly and without the ability to flow smoothly. Latex paints were never meant to be sprayable. Thinning latex paints results in poor transfer of paint solids to the surface. Latex was designed for application by non-drip brush or roller. Before water based paints, oil based paints could be thinned for spraying without much transfer problems. Latex paints (water based) are different. They lose their transfer ability by thinning, a necessity when trying to spray it.
The only success I have had with spraying water based paints(latex) was by using an airless sprayer.

HF probably arrives at that 1.5 CFM @ 30 PSI by using a very small orifice.l

The owners manual on the second one says it uses 6 scfm. The first one uses 4 scfm 50 psi so it would be close to 1.5 30psi. I have a couple of their guns and like them. I also have a small earlex hvlp turbine that is under 100 bucks and works well. You might want to go that route. I think Graco makes one as well.

My dad had bought one of their kits when I was a teenager. Worked fine for oil base, as to be expected from any other siphon feed gun. I’m not sure about that weird cfm number (a lot of their tools have odd cfm ratings). Do make sure that you have a sufficiently sized air compressor. I’d recommend at least a 2hp 220v belt driven model. Anything smaller or oil-less direct drive will drive you nuts. If you need a cheep upgrade, search for a 220v compressor that someone doesn’t have a 220v circut to use it on. I pick them up for cheep regularly, like $20-40 cheep. And, if you find a 1hp model, they are usually dual voltage. You will need multiple filters do deal with condensation in the air line/tank.
