Increase air compressor capacity with auxiliary tank

Increase the capacity of your air compressor by adding on an auxiliary tank.

it would be good to list the items to be used. Thanks

Way legit idea, I am currently spraying a customer house currently and would love a bigger compressor minus the cost/space needed to store a larger tank

[roadkillsf.f.cgarage]

I done the same except I put the regulator after the T so it regulates both tanks before going into my tools

[Mr_Eyeholes]

Seems like this can only fill your aux tank to the pressure the regulator is set for, though. Still good, but won’t reach max capacity.

Hi can you please breakdown all of the extra parts you used? Great video. Thank you!

[johnladouceur]

So what is the advantage? Your compressor either cycles more with less capacity or you wait longer for the compressor to run the same amount of time to fill the two tanks..

[Jerry_ct]

The tee need to be in the middle of the regulator and the pressure gauge on your main tank.

[BOOMER]

Aha! I used and adapted the same HF 10 gal. auxiliary tank that you are using but I connected it in with my McGraw 20 gallon compressor but didn't seem to increase the capacity. The McGraw would still use air too quickly (when using HVLP spray gun) and run constantly. Now I see It should be connected in ! Thanks for the video!

Looks like maybe you could put the "T" between the Regulator and the Pressure gauge....that way you could still fill both tanks AND Regulate the pressure from both tanks at the same time...other wise...like ian said...you would be putting full pressure from the Aux Tank to your tools.

Great video. Can you link the extra parts you used to connect the extra tank ?

Having watched a lot of the Videos on how to add another Tank, in order to add to your Air capacity, I did mine a bit different and it seems to be a lot easier to do.
It seems as if every Portable Air Tank, are all basically the same.
They all have the Air Gauge..They all have that Car Tire / Bicycle Tire type of Filler Valve ( its called a Schrader Valve ) with the Screw In Open and Shut feature on it. And they also come with a pressure release valve and of course they all have that Air line that usually comes with an Air Chuck on it.
Not to sure if I am doing this right or not?....But....I found it just as Easy to just screw out the Air Hose Line, and then just screw in a Quick Disconnect Coupler.
It seems to work Great, for Filling up the Portable Tank, and for also increasing the Volume of Air that you now have, by adding on an Extra air tank.
Oh....almost forgot, I had to make a little connection fitting, in order to Connect the Two tanks.
It's so easy to do....you just need Two "Industrial" 1/4" Male Nipple Fittings ( They call them Plugs ) and One little Female adapter or coupler. Or....I now see, that you can buy a package of Two Male/Female 1/4" Plugs at Home Depot...where the Two Plugs will screw into one another....which will eliminate the Female Adapter / Connector.
I really do not see any reason, to have all those T's on the Tank?
I might be wrong?....but it seems to work Great for me.
I might....put an On / Off Shut off between the Two Tanks, but....right does not seem really necessary?
Question for you come they have that Screw in "Wheel" on the Schrader Valve?
I just leave mine Open all the Time, and it doesn't seem to make any Difference, if it is Open or Closed????
So....with this simple modification, of putting the ONE "Quick Connect" coupler on it, I can now FILL my Portable Tank via my Compressor ( and by pass that Schrader Valve all together ), and I can also Add to the other Air Tanks Volume.
I just can't see any reason, to take off all of the Original Hardware?
Just leave it all on, then you have the Safety Release Valve, and you have the Air Gauge, and you don't need to be adding all of those T's, as some of the guys have done.
I might be method seems to work Great?

If you’re using the regulator at low pressure, the extra tank will take a while to fill and you won’t get proper air pressure

[michelangelopainters]

Does this setup help keep water out of your lines? Maybe if you had an outlet coming off the auxilliary tank because that air would have settled and cooled more, I guess.

[johnbaumgartner]

Kam, Thanks for the videos on this and the Aux Tank setup. I only have one question. Without a drier between the two, how would you drain the water out of the Aux Tank. Does it have it's own petcock for drainage?

[jeremydemary]

Thank u for the video it helped me figure out my air compressor

[csimet]

Great setup and exactly how I did mine. Retains safety on both tanks and allows use as auxiliary or portable operation.

Question... since the aux tank is now on the regulated side of the compressor, it only fills to the set regulated pressure and not the main compressor tank pressure. Would it be better to put the tee where the safety valve is... put the safety valve on the tee (so the compressor tank retains a safety pressure release) and use the remaining connection to run to the aux tank via a quick disconnect (the same setup you made). That way, any tool connection to the compressor remains at the original regulated side and you can remove the aux tank at will. The "downside", if you call it one, is the aux tank is at full pressure and not regulated pressure. It is assumed that the aux tank has the same pressure rating as the compressor (usually 125 lbs.), of course. Thoughts?

[Serjanttt]

2:17 NO because it is connected after regulator

[LuisOntiverosv]

If my compressor have two out ports, can I just connect the auxiliary tank to one of them and the other use with the hose and tools?

[TekMan]

I have the 33 gal electronic motor craftman comoressor that works good painting car panels thought about modding it with an extra tank to do entire cars. Might have to consider doing this for a big project I have coming up soon.

[daljeetsinghsokhey]

I have a ctaftsman pan cake compressor that cuts off at 135 psi. The HF aux tank has a max capacity of 125 psi. I cannot connect it at the unregulated point on the compressor bcs of the difference in pressures capacities. What's the solution ?
