Dual Tank Compressor?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

RPBurris · 12-08-2011, 05:42 PM

So i currently have a compressor that isnt worth the space it takes up and is probably about 10 gallons. There are plenty of 20 gallon units out there that put out decent cfms. My question is can you put the tanks in series? I would take the compressor unit off the smaller unit and plumb them together to try and give me more volume. Has anyone done this and does it work?

Yes you can add an additional tank for more volume, but keep in mind, if your compressor does not have the CFM to support it, you may do more harm than good.

The pump should be sized to the tank it is on. Adding a tank will only add surge capacity (short high volume blasts). What the additional tank will do, is drop a bunch more water out of the air. Shouldn't hurt anything though.

I've piggybacked my baby compressor with my 60gal when I've needed more. Both ran the same pressures. Baby feeding the 60, then out to tools. I don't make this a habit, at the time I needed more air and stepping up a bigger 80gal unit wasn't going to happen. In theory, the 60 should have ran everything fine, but didn't quite have enough.

If your trying to get 2 little ones to equal a big-un, personally I'd bite the bullet and pony up the cash.

My baby compressor was an 18 gal, oil-less (Home Depot). More than once I had to wait on it just running a nail gun.

my main compressor is a 60gallon unit and i've run an old 29 gallon tank in series with it hooked up to my blast cabinet and pot blaster and as stated it works great as a secondary water seperator and it does help with the airsupply situation somewhat

no ill effects from lots of use over the ten years i've been doin it that way

also doubles as a portable emergancy air tank when i get stuff that needs moved and have flat soft tires

We run 2 tank at work one 80 gallon one 100 gallon tank linked together but we only run one pump at a time it runs work about 4-5 mins when the pump kicks in ours cuts on at 110 and off at 175
