I'm about ready to plunk down the dollars for a Powertank System. Do I go with a large tank to save on refills or a small tank to save on space? If you run a Powertank tell me what size tank you have and if you had it to do again would you go to a different size and why?

Thanks, Red

 

I have a JKU and went with the 20# tank with the powertank mounting bracket and rollbar clamps. I mounted it to the passenger side rollbar and it is rock solid. As you can see in the pics it has about 1/8 of an inch clearance ate the top ( with the nylon handle cover on) and about 1/4 inch from the factory sub and the hardtop glass. It sits at about 55 degrees so I don't even pull it out when filling tires. Occasionally I will take it out to another rig on a trail to help air up or use air tools, and of course to refill. It cost me 25$ to refill it at a fire extinguisher shop. I personally love the 20# tank. In the JKU it doesn't take up much useable room and lasts quite awhile even when running air tools. It is maybe a tad bulky when hauling outside the jeep but I have never had a problem where I wish it was smaller.

 

10# here. I'd suggest u take a look them in person at a local CO2 place. I can't see why you'd want bigger than a 10#, personally. A 20# is a big tank. Just my two cents, but a 10# seems like a perfect fit for a JK. I usually get 4 tire fills out of mine with 37s. Plenty fine for me. I have OBA for tools, though.

 

10lb here to , when you say 4 tire fills are you talking only 4 tires or 16 tires 4 sets , because I get 12 + tires out of mine with 37's

 

10lb here, 16 plus tires (37's) aprox 2lb per 4 tires. They never fill all 10lbs due to the over pressure safety if it gets too hot. No fun if it blows in the cab. I built my own system with mix match stuff. Saved $$$ ie aluminum tank form a beverage company, regulator from out back air, hose and chuck from power tank. You don't need a gauge because it goes by weight not pressure.(they want you to think you do) It will show max pressure when it's almost empty. Got a digital fish scale from wally world to weigh the tank before I go out to make sure there is enough in it.

 

Yeah, sorry about that. 4 trips x4 37's.
