What Volume Compressor For A Small Garage Workshop?

Another option is to hook 2 or more compressors together to get the CFM you need. You don't have to run all of them all the time, You can have only one on for blowguns and light air consumption tools etc then turn on the other(s) as needed for heavy consumption tools.

Not to hijack the thread, but I have often thought about doing this. How would one go about doing it ? Where to interconnect ? Btw Eddyde , my uncle is down on E 26th st in Sheepshead bay ...good times down there thru the 70's and 80's !

Hi all,

I'm getting to the point where I can outfit a small workshop for myself (12'x31'). I'm going to have a CNC mill with flood coolant eventually, and would like a couple of air hoses at benches, plus a sand blaster as well as the usual small shop machinery. Just wondering what tank size I should be looking at and what CFM's? I might build a dedicated enclosure for it outside the main workshop to limit noise and free up some space.

Any thoughts appreciated, thanks.

I found 2 hp @ 100 psi works for hole shop
When had large shop found a 3 hp @ 100 psi worked great

I agree that blasting uses a lot of air, therefore I recommend the biggest compressor you can fit in your price range and allotted space.

The simplest way is to make a manifold out of a tee and quick connect fittings to simply combine the air hoses from each compressor into one. Keep in mind, the max pressure setting on the larger compressor must not be higher than the smaller compressor is rated for. It may take a little twerking of the cut in and cut out settings on the pressure switches, to get it working smoothly. Another way would be to control all the compressors off one pressure switch, this could be done with a relay.
