Looking to purchase pneumatic paint sprayer

Hi,
I have an air compressor (I believe it is a 3 gallon one) that I am currently using with my stapler for my upholstery projects and it works great. Now I am considering purchasing a paint sprayer that I can hook up to the compressor as well in order to paint furniture I have. I was reading about the "non-bleeder" type... any suggestions on where to buy one that can hold a decent amount of paint for these types of projects?!
Thank you for a response!!

Welcome to the forums!

I doubt your air compressor will support a spray gun. Cup guns typically use a lot of CFM. You need to check the CFM rating on your compressor [should be on the label] and then compare it to the gun [or any air tool] you wish to use.

I have 2 air compressors, my 1st one is a sears 1hp, 11 gallon tank. It works real good for spraying minor items like doors. I have sprayed cars with it but I'd have to stop and let the compressor catch up. Once the reserve is used up, you have to wait for the compressor to rebuild the supply of air. Now days I mostly use my 6hp, 60 gal tank compressor.

Most cup guns hold 1qt of material, the less working pressure you have, the thinner the material needs to be. There are also 'door jamb' guns that typically hold 1 pint, maybe a little less, then there are the 2 gallon pressure pots - but they need a compressor big enough to support them, you can't fudge much with them.

Flijenny:

Car enthusiasts will often use small air compressors of the kind used for pneumatic nailers and staplers, and use them with low volume low pressure spray guns to paint cars one panel at a time.

You may want to check out the Iwata LVLP spray gun that these guys are talking about (and check with Iwata that it can be used for latex house paints):

While I own a couple of HVLP guns, I'd never heard of a LVLP. A search for LVLPs revealed that while they require less CFM than many conventional cup guns - they still require 7-10 CFM which would be way over the capability of a small compressor.

Generally, a 120 volt compressor is going to struggle with painting, a 240 volt compressor is usually required for this

Well, this place sells the Iwata spray gun:

Iwata LVLP Spray Guns

They'd be the best ones to refer questions to.

I'm thinking that for $378, that gun has to work reasonably well with automotive paints. Whether it works as well for architectural paints is another question.

According to the specs for that gun Iwata Low Air Spray Gun it requires 9-13 CFM which is way beyond the capability of a small air compressor. It's also kind of pricey for the average diyer.
