How to add tank on a small air compressor

This small air compressor looses air too fast, so I added an auxiliary tank to last air a little longer

[@bobbrinkerhoff3592]

I did this same thing on a larger scale almost forty years ago , running a 5 hp. 30 gallon Craftsman into a 100 gallon tank . I ran this set-up for over five years with no problems, only tearing it down when I moved to a smaller location , and we used this to mount and dismount tires up to 44 inch diameter.

[@cesar8359]

That's nice, I hope mine will last that long too. Thanks for watching.

[@southern_merican]

did u just let the compressor fill the 100 gal in one go? or did u give the compressor a break, to keep from overheating?

[@bobbrinkerhoff3592]

@@southern_merican let it run , it never overheated .

When wrapping the tape on the threads, go the same direction as tightening. Keeps down leaks and makes it easier. I did the same tank set up you showed. Works great. Good video.

Thanks for the video. It's surprising how much harder it is to watch a video with annoying music instead of useful narration (no offense to composer or to DJ that selected it, all music in videos is annoying). I didn't have the patience to endure the whole video. Again, thanks for the video. Just wish youtube would warn us which vids were music instead of narration BEFORE we sit through pre-video commercials.

[@cesar8359]

Thanks for your patience in watching my friend, next time I will try my best to explain or narrate the things I am doing.

[@Infidel67]

It's a good Idea and it works, have done it myself over a year now and the motor is doing fine, it runs 8 hours a day, it's just a booster tank addon.

Tanks are sized off of the duty cycle rating of the electric motor. Twinning two tanks together might give you longer periods of time between compressor cycles but you also made the compressor and motor run longer to top off the tank.

[@markluxton3402]

I had a similar idea. Check that the portable air tank has the same pressure rating. Mine is 10 pounds less than the original.

[@cesar8359]

My portable air tank is rated 100 psi and the auxiliary tank that I added is rated 125 psi. Thanks for watching

[@poncematagolai7456]

That little plug with the ring at the end of it ? Is that like a check valve?

[@user-op6uv5bx1r]

Thanks for the video It is better to leave the pressure release valve even in the large tank Double safety

Nice tinkering. But the 2gal compressor motor are not designed to run that long . It gonna run a lot longer 3+ 11gal , 14 gal or4.5 X longer . The throughput of the pump is still the same . You will have the first tank capacity . But then you have to wait a lot longer for the tank to reach max pressure . I would rather wait till the compressor to catch up with the 3 gal tank than 14 gal tank . It’s a good tinkering .

Stop complaining about the music and just mute it if you don’t like it. He doesn’t talk anyways.

[@alanmajors9100]

If anything, I'd say you are smoothing out run cycles for the little pump. How frequently and for how long does the pump run under similar loads with or without the extra tank?

[@cesar8359]

If without the extra tank, it will take less than 6 minutes to run. If the extra tank is added it will run about more than 18 minutes. Thanks for watching.

[@davebrookbank4831]

Yep I am planning to add 20 gal old tank that the motor wore out on. My new compressor is quit fancy for me it is a 10 gal I believe with 2 separate connectors on it so you have 2 circuits, all I am planning to do is bore sight the old tank and clean or treat it as needed then just cut a short jumper from the new 2 circuit tank to the old one. I believe it should fill the old tank with just 1 hose and as I use the new compressor the old tank will empty into the new one as needed. I am a pretty good DIYer but I have never tried this before... I THINK it will work.

[@shatnersufolanded7785]

Can I do this with a double stack tank from northern tool its only 90 psi 2.6 hp 4.3 gallons but I want to add a 9 gallon auxillary tank that was 125 psi. Somewhere I read you cant do it unless both tanks are within 10 psi of one another. Great video.

[@cesar8359]

Well I just experimented it on mine and I don't condone you to do it but if you are willing to do an experiment like I did, it's your own decision. Thanks for watching

Could you just have run the air line that would go to the tool from the original setup, but run it to the auxiliary tank (with original regulator valve fully open), and duplicate the hardware setup of the main tank on the auxiliary tank (pressure gauge, regulator, pressure valve, airline connector to tool). Am I wrong to think by doing it like I propose, it would allow to use just the original tank if you wanted to, just like before by running the airline to a tool instead of the auxiliary tank, OR using the secondary tank ? Is it because of the extra cost of the hardware to do so ? Or am I understanding this all wrong ? Also, one (major ?) difference between the original setup and an auxiliary tank is that the original tank has 2 holes it in. One with air comming IN from the compressor, and one with air comming OUT to the regulator, pressure valve and gauges. The auxiliary tank has only ONE hole it it. So it is a problem to have a potential situation where the compressor will be trying to push air in the secondairy tank while the tool will be using air, and those two airflow (in and out) will meet at the same "T" junction over the unique hole of the secondary tank ?

[@cesar8359]

That was a massive good questions but your first question is I believe it's possible, you can do that I guess. 2nd question is also possible. 3rd question is you might be right, a good solution might fix it. Thanks for watching

[@SILVERK5]

@@cesar8359 Thank you for the answer ! I obviously want to increase the volume of my compressor WHEN NEEDED, while being able to EASILY return it to its original configuration (nice portability of single small tank).

[@Isaiah5417GdLk]

crazy, i just did the same thing the other day, only difference i left my compressor as is and just quick couple to my other tank, then barely crack the valve so my compressor gets a rest then back on again to initially fill up the second tank, once full i open the valve all the way. The reason i did this wasnt so much for all the time volume, only to give my impact more startup uga ugas. ( I don't do alot of heavy impacting,.)

Hey great video. I was wondering can you swap your tanks original tank with a new one? I bought a used compressor and want to put a new tank on it so I don't have to worry about anything.

[@cesar8359]

Thanks for watching, yes you can replace or swap the old tank with a new one.

[@Dnasty1]

Does it require much customization? I see a lot of welded brackets and special holes.@@cesar8359

[@mrmotofy]

Uh that's like a .7cfm compressor and will take 643 days to fill that tank. That's way over the duty cycle and will likely die quickly under normal use. Get a real compressor with 4-5cfm at 90psi or better

But aren’t you then stressing a pump motor designed for a 3Gal capacity to 14Gal workloads? Seems like a recipe for burning out the pump motor to me. Nice try though…

[@cesar8359]

It's a small pump but let's see how long it will last.

[@regularpit1508]

It will shorten life but if it's an oil free design it's not meant to last long. You need to check their duty cycle if it's available. If it is an oil free design then put 3in1 silicone oil in the crank portion of the compressor and let it dry then turn it on. I would clean out the dirt from in or around it as well.
