I know its prob been covered here before, as I have read about it being done... But Im going to ask as I still dont understand.
I just bout a 6 1/4 horse power 30 gallon air compressor a weeek ago. I have yet to use it for anything other than impacts and stuff. But I was told you can hook it up to another tank, and have a 60 gallon tank... it'll hold air longer, but take a bit longer 2 fill up... So how do I do this?
If I get an extra tank how would I plumb it?
I know from the airoutlet on my 30 gallon tank would go into the inlet on my other tank... but where's the inlet if I get another tank like I got?
Having another tank will slow down how soon the compressor will start. But will also increase how long it runs after you are done with using your air tools before it shuts off as it has to fill both tanks to pressure first.
68 Torino, Thanks. I figured that much.. I just wnated to know how to connect them. I appreciate both of your help tho As the info was much needed. I'll see what i can do w/ the tanks
Andysutt, one note to remember. If you pair up another tank, you may go over the duty cycle of the compressor motor, which would mean an early death. This is particularly important with the newer "oil free" design in which the actual compressor head doubles as the motor end frame.
It all depends on what tools you plan to use. Impact's, air ratchets, air chisels, paint guns, blow guns, air assist jacks, and other low volume tools are ok for the most part. High consumption tools like high speed angle grinders, die grinders, sand blasters, board sanders and DA's would be more difficult to use to they're full capacity.
If you want to sister up another reciever tank, then maybe add a 10 or 15 gallon, but I wouldn't add another 30gal. If the two are going to be free standing, make sure you use a short flexible hose to allow for any movement or vibrations.
Thanks for the info Freigh Train. I didn't plan on using it like that all the time. I was gonna put a T there w/ a short hose to the other tank for when I use grinders, or actually do my paint job on my truck (just so I dont have to worry about no air)
and stuff like that.
I will be doing a bit of sandblasting and Id rather it run longer, fewer times, than for short periods of times every minute or 2.
Thanks again
If you add the second tank in line, you cool the air and get rid of more water in the air. This is what I did with mine.
Line from compressor to top of second tank, then line from second tank to your tools. I noticed that when spraying it greatly reduced the water. It offers the air a chance to expand into the second tank and then the cooler air is drawn from the top of the second tank.
The T fitting will work great for regular tools where water and temp aren't as important.
I have a friend that put a 30 galon auxillary tank on one of those cheap pancake compressors and has been using it that way for 3 years now. I have been around there when that direct drive has to pump for 10 minutes to catch up and I would consider it a bonus if it killed that noisy sucker. So far it hasn't.
