You'll just have to fill up twice as much. More of a hassle thing than anything. But you'll be able to air up and down a few times before you need to refill. I"d save up for at least a ten pound tank.

 

Well... I don't have one, but i like the 5lb size. From their chart, you should get more than three "air back up's" (i.e. 20lbs back to 35lbs with stock size tires) on one tank. The smaller size would be easier to stow and extra tanks are only $120. I'm thinking about it as an addition to my little flow master inflator. JMO.. Ron

 

Power Tanks are too expensive. The competition has the same goods for much cheaper. If I knew how to do this forum stuff I would post a link to the group buy I saw the other day. A 10 lb tank adjustable regulator (that won't freeze) handle hose and air chuck for 288 dollars or something. There are numerous competitors , Ultimate air, The Source and others . Shop before buying. If you are crafty you can make you own . Hospital supply , Soda supply , welding supply stores should all sell the tanks for very cheap.

 

I know the ones, they are on ebay all the time for the 10 lbs for 240 to 280 every day. 5 is nice but as stated you have to choose between more trips to the fill store and less usable pressure.

 

Yeah, but once you get that 5lb tank, you will see how useful it is and start to mess with things. Pretty soon you will have air tools and wish you had gotten a bigger tank.

 

I have the powertank regulator with a 5lb tank we got from a welding shop.. running stock size 265/17 BFG AT KO tires. We can fill 8 tires from 15 PSI to 40PSI plus a few small fills (from 38PSI to 40PSI) and random air spray with the 5lb and that was about emptying it. I am thinking maybe 9 tires from 15PSI to 40 PSI will be pushing it but 8 is enough for our purpose so we are happy with it plus the tank is small. The welding shop is just next door to the office so filling the tank hasnt been a hassle yet.

 

If you are just going to air back up doesn't a 12V air compressor make more sense?

Much cheaper and lighter. I know it would take longer.

How long does it take to air a stock size tire from 20 to 35 with a typical 12V air compressor?

I have the Viair 200PSI system and love it. But if you want to run air tools and your in a big hurry you'll need a CO2 tank. When my air tank is at 200psi it takes about 15 seconds to go from 15psi to 35psi on 33in tires. But then you have to let the tank refill. The compressor automatically goes on if the tank pressure falls below 170psi or so. If you are airing up strictly using the compressor (tank isn't charged, or don't have a tank) it takes considerably longer. I haven't timed it though.

 

I have one of the small air compressors and they work but take a very long time to re inflate mt 35's. I finally bought a 10lb Powertank setup after watching all of my buddies air up and leave while I was on my first tire! Bob at Powertank is a great guy and great to deal with. As the old adage says you get what you pay for. I have a friend who has one of the others mentioned above and he has a problem with it emptying itself when it gets cold here in the Northeast. Got hung out to dry a couple of times. I don't think you have to worry about freezing in Califronis but it's a problem up here. Good luck with your decision and just save to buy a 10lb tank, you don't realize how handy it is to have the air available until you have one.

 

I carry a 10lb power tank plus I've got a firestone air compressor plumbed in the engine compartment......I also bought a spare 10 lb CO2 tank which i keep in the garage....it's handy...i think 5lbs is too small....too many fill ups...filling the tanks are a pita.....

the best bet is to wheel w/ someone like oldschooltoy....he carries a gas powered air compressor and i just borrow his air....lol....:rofl::rofl:

 

What sets the PowerTank Systems apart from the rest? What constitutes the huge price difference? The Ultimate Air system is considerably less expensive...why?

I'll be getting an on-board air system in the near future and would like to buy it just once.

Is there a comparison article about the different on-board air systems/brands?

Thanks.

 

Anyone have experience with HyperFLO MAX Source™ systems?


I'm looking for a less expensive alternative to the Power Tank Systems. I don't know enough to decifer the differences between one system to the next.

Thanks.

 

I'm running that system, but with the upgraded, adjustable regulator.
I'm extremely happy with it. Demello Offroad (a supporting vendor here) sells them also.

 

my understanding is that the powertank regulators don't freeze up like some of the others.....yeah....i know the powertank systems are pricey.....the 12v portables work fine...they just take a long time to fill up.......:rofl:

 

I use a scuba cylinder and a cheap first stage regulator with a long hose attached. you can pick up used scuba tanks and regulators really cheap.

I just browsed ebay and craigslist..

used 80 cubic foot cylinders $80.00

used first stages 30-50 bucks.

If you have a dive shop nearby talk to them they might have some old rental gear they want to get rid of. The only problem you might have is filling them I always fill at a dive shop but I have a ton of scuba certifications. I think if you explain your use to them they will fill it no problem.

 

I just received one of these from a group buy here. Very pleased.
