Portable Air Tank

Neal · **Posted:** Sun Sep 28, 2008 11:59 am

Wondering if a portable air tank is practical for re-airing up. Has anyone used this, if so would a 5 or 10 gallon tank filled to 125 PSI be enough to fill 4 tires from 20 back up to 38? Harboe Freight has a 5 gallon for $30 and a 10 Gallon for $35, don't want to go any bigger than necessary, but want enough to refill at least once per trip.

My 7 gallon tank at 125 psi will get me from 20 to 33 on 265/75's... enough for me get to a gas station when I leave the trail. I'll be replacing with a CO2 cyclinder soon.

How many air-ups do you get from a c02 tank and what does it cost to refill the tank?

daspes · **Posted:** Sun Sep 28, 2008 1:17 pm

depending on size of the tank about 100-150 fills.

Neal · **Posted:** Sun Sep 28, 2008 1:19 pm

and how much to fill tank?

I'll someone else chime in, but I know it isn't that expensive, when you compare it to how much use you can get.

depends on where you go 14/15 bucks or so around here, CO2 is the way to go, have a 20 pounder for mine, not in there yet, but have used it around the garage. Initial buy in price is a lot higher but long term its cheaper and better, can air up after a run in a very few minutes on all 4

I personally got tired of the Co2 tank and switched to portable compressors. I run a Quickair II in my TJ now and then I bought a Tsunami for my other vehicles. For $60.00 it works great almost as well as my $300.00 (or whatever it cost my wife to buy) Quickair. Co2 always was a pain to keep filled and seemed to run out at the most inoppretune times. With the portables they are always ready and I never have to worry if they are full before I head out. I decided to give the Pep Boys special a try as I had known others that had them and they seemed to work well. I have had mine about a year. It takes around 15 minutes to fill my tires (245/75R15's) from 12 to 32 psi. If you are impatient or want the ability to run air tools this is not for you. I tried protable tanks way back and gave up on those rather quickly. They just don't hold enough air.

For the KJ and the other vehicles, Pep Boys special

That's a big bottle.

I've been on the bottle for about 5 years now. Never leave home with out it. All that noise from those little compressors drives me nuts.

Costs me $30 around here to fill up. I just heard a refrigeration place will do it for 20 but someone also said that place doesn't always fill it full. The guy I bought my CO2 system from said the 10 #er I have will fill forty 33" tires. It is silent, and takes just over 60 seconds per tire to go from 15 psi to 35 and at $185 out the door, was a good deal.

My write-up on mine. http://www.lostjeeps.com/forum/phpBB3/vie ... hlight=co2
Love it! I can be aired up and moving in a couple minutes instead of waiting for about 10-20 on a small compressor. I Do also have an ARB compressor for my air lockers so in a pinch I could use it too. I top off my CO2 once a year and it works fine for a season of wheeling which often includes airing up others. only $12 to fill it around here.

X100 on the CO2
I have a 20# main and 2 5# back ups
when the 20 gets down low ,you can tell by weight, I put a 5 on the back floor board
I run air tools like an impact ,air ratchet and air cut off tool ,great for bent tail pipes
now I get mine filled for free and most times bring a 20 and a 5 at the same time but I take a 5 on EVERY road trip we take ,that and the impact and socket to remove a flat ,and a plug kit to plug a nail hole
I had the Vair 350 compressor and a tank not even close to the speed of CO2 and air tools were out

this is how we handled on board air... but i dont think it'll fit in an ARB

however a custom bumper is always an option. does all 4 35's from 14-32psi in about 8mins... but it cant do the air tools that C02 can. added bonus.. a 10,000lb winch with 125 foot of cable

I also have a 20 pounder................It's big, but I wanted something that I could use on the Farm/Ranch, take on road trips (towing my travel trailer), and still be able to use it for off-roading. It's overkill, but I'm an overkill type of guy. If I were just using a bottle for off-roading, then I would go with a 8-10 pounder.

a 10 pounder is good a good size for the KJ. I looked into it but just couldn't afford the initial cost. I went with this: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=93186

I have about a dozen times so far. I can go from 18 to 35psi in 245/75R 16's in about 3 minutes per tire. It gets really hot by the time I fill all four tires and its noisy too. It's not as nice as a CO2 system and I will eventually go that route but this works for now.

I've not timed my air up from 15lbs to 40lbs, but I'd be very surprised if it even took a minute per tire. With a 150lb regulator, my CO2 tank fills the tires QUICK.

Was wondering if anyone has found this same PowerTank package for less? These things aren't cheap.

The regulator alone is more then worth the price,ask JJ.
