Shop compressor
There are a few threads on compressors I know.
For painting, is a 60 Gall tank and either 12.3 or 13.4 cfm @ 40psi ok? & any recommendations on a reasonably priced spray gun FYI. I am not considering painting the 911, however as I am getting a new compressor for the garage, my boys want one that they can paint their cars with. Thanks. Griff. |

Paint guns vary, most suction models require up to 60 PSI@ 14 cfm
HVLP guns work in the 10 to 25 PSI range @ 10 to 13 cfm A 60 gallon tank is great but I prefer an 80 gallon compressor. Go for the biggest possible compressor that you can afford, ultimately, it will make your work easier

Get a 40 gallon compresor and buy a second 40 gallon reservoir. Use the reservoir when you're painting, but otherwise you won't likely need it. And you don't want to wait for an 80 gallon reservoir to charge every time you want to use an air tool.

That makes sense to a point. It's very easy to run your air tank dry when using air powered impact guns, cut off wheels, die griners etc. so, that's why I suggest that you get at least an 80 gallon compressor

FWIW, there are ways around having to get a monstrous air tank for you garage. I painted my 68 Bronco using a 30 gal Craftsman with something like a 7-8 cfm rating. The key is if you are only painting once in a while to size the gun to your compressor. If you do LOTS of sanding and painting and grinding, yes the big tank will be needed. I do a lot of hobby work, including the restoration and paintin of my Bronco and only when I was sanding the roof to bare metal did I feel the compressor was holding me up. I used a Sharpe Platinum, which has about a 7-8 CFM rating and my pessure never dropped below the 40 psi or so I was using.
YMMV

The Devilbiss Millenium HVLP gun needs 15.5 @ 30 psi.
this harbor freight gun needs 9.5-14.8 CFM There seems to be a void between the good home shop air compressors and the ones for HVLP $600 for the former and $1000 for the later. I don't think the tank size is as important for HVLP as the cfm rating since the tank will empty out in 10s of seconds. Now you have to worry about cooling the air and drying it. |

Rick-l brings up a good point about cooling and drying the air. I you are wanting to paint, go to sharpe1.com for recommendations on piping layout and other great info. I bought my Platinum HVLP-low volume as a factory refurb for $175. This was half price. If you check out the "ask Dr. Gun" area you should find details or can ask about getting a refurb. This is one of very few guns that does not swallow huge amounts of air. As a side benefit, it paints slower (why it uses less air) so it is a little easier for a noob to paint.

I bought an Ingersoll Rand 2340L5 60 Gal- it is perfect size for any home shop need- runs my tire machine easily, will handle most air tools and last forever.

I wouldn't want to paint an entire car with anything less than 80 gal. Must be installed properly so the moisture is at a minimum. If you have a crappy paint job because of compressor problems, the second trip to the paint store ($300-500) will make a larger compressor seem like a great deal. OK tools = Ok results, Great tools = Great results.

I purschased this unit about 6 months ago, prior to painting my car. I've been extremely happy with it. I had a Craftsmen 3hp 30 gal unit previously that would always run out of air. I've used 2 DA sanders at the same time on the new unit and never ran out of air. Only down side is the shipping is pretty expensive. If you compare cost plus shipping to almost any other unit of comparable volume and displacement, I found this unit was still an excellent value.
