Spray Guns

#41
One more question. Can I run paint guns through this portable compressor? It'll generate 100 psi (probably not continuous, but for painting a body?) and has a 2 gallon tank. If not, I have a big compressor but was looking for portability.

I really don't want to paint inside my shop as there are too many things )motorcycle, tools. etc.) to get in the way so I'll be painting outside. The little blue compressor would fit the bill nicely. If not, I'll be picking up more hose. Pics below of both compressors.

Any input welcomed.

You'll probably be ok with the small one. You could connect your gun and hold the trigger to get an idea of how much air it uses and if the compressor can keep up. I used a dual tank 4 gallon compressor to paint bumper for years without any problems.

All my hvlp's work fine with a regular compressor. I would never spray with less than a 15 gallon compressor. Mine is 17 and can barely maintain full pressure at 40 psi through one full coat of a neck thru bass. Most portable compressors are designed pretty much for nail guns and tire inflation. You'll most likely find yourself constantly running low pressure. It's gonna wear out the compressor sooner and you'll
likely have trouble getting a consistent finish. Just my experience. :bassist:

That little compressor doesn't have enough volume. It could work with an external volume tank, but you would probably burn up the motor after to long. That 20 gallon husky is your best bet.

Thanks for the input Big B. That's what I was looking for. Now I know where to install my inline filter/water separator for this application. I won't need it all the time, so I'll likely mount it with jacks I can plug my main hose from the tank into and my paint hose to my gun coming out of it.

Thanks again for everyone's input. It is helpful and truly appreciated.

That's another benefit of HVLP- the pressure release isn't as extreme as when a regular gun and compressor are used. Changing from high pressure to low pressure is why water condenses in air lines and compressors. If you're using a regular compressor, you should have a good permanent water filter in line. All of your tools will last a lot longer if you have one. On a hot & humid day, some tools, like die grinders, will spray water on whatever you're working on.

Got my inline filter installed. I didn't want to use the filter all the time so I installed some hoses on either side to connect it to my existing hose, and then be able to come out of the filter which is also regulated and go to what ever gun I was using at the time. I'll go soon and get some more hose which will be used for paint purposes primarily. Pics below...

And in closing let me say that this is Texas. You just can't have too many guns. LOL

Thanks for the input Hopkins. Read the above if you haven't already. I'll be shooting with the big compressor and have the air regulated and filtered. I'm getting pretty excited about this whole operation!

I bought some very nice DeVilbliss HVLP guns without knowing what I was doing. No way was my Craftsman 26 gal, 3HP compressor up to the task.

Used one gun exactly 2 minutes before the compressor died. (PLEASE NOTE: Using the HVLP gun did NOT kill my compressor--but it wouldn't have been adequate to the task of running the guns. Just didn't flow enough air.)

The better option for the small compressor is the LVLP guns. I found that I either had to spend a LOT of money for a compressor, or a lot of money for the gun. One or the other.

Ended up buying a dedicated turbine spray system and skipping the whole thing.

I am in the auto painting business with over 20 years experience.

Gravity fed guns are the only thing anybody uses anymore, been that way for years and years. The guy who said you can't get enough material to avoid orange peel has no idea what he's talking about. Orange peel is the result of too much material not applied correctly.

Gravity feed guns require less pressure, which is essential unless you have an industrial sized compressor.

There are plenty of cheap ones out there that will work for you

Unfortunately craftsman compressors are garbage

Thanks for the great info! I am looking at a gravity fed gun and I got the okay from the wife to buy one. Of course then she got the idea for me to spray some furniture :)
