Nitrogen Tank

[convoy]

Where have people found the best places to get nitrogen tanks and regulators from?

I was looking at www.polyperformance.com website for a nitrogen tank set up.

Regulator: $90
Hose: $60
Tank: $82

Total $232

The kit has a fancy case and a nice fill adapter for twice this cost, but I'm not to worried about tuning a shock to the accurancy of 1 lb or a nice case.

Anyone found cheaper???

did you try your local welding gas store ? (airgas or general welding) they usually have a large assortment of tank sizes and guages.

i found these guy's just after i bought my steel bottle from (Madco) a local weld supply....i'm buying a couple soon for my bro's bronco and my superduty

Griffin, i came across this at rdc http://www.race-dezert.com/cgi-bin/trader/atl.cgi?ct=2&md=second&id=1147

Thanks Nick I saw that too...no hose and it would be perfect for a shop, but the bottle is too big.

If you're planning on using your cylinder for running air tools and inflating tires, you might want to consider getting a CO2 setup rather than N2! The initial cost is similar, but you'll get a lot more "run-time" from a CO2 setup! The small nitrogen cylinders contain 20 cubic feet, compared to a 10 lb CO2 cyl that holds around 90 cubic feet*! If you supersize to a 20 lb tank, then you get 180 cuft*! If I recall correctly, It's about $10 to fill either a 10 lb CO2 or a 20cuft N2!


* rounded numbers at 1atmosphere and 77 degree ambient temp!

I'm running a 20lb Co2 tank. I read an interesting article in the latest issue of four wheeler, long story short, race teams use n2 because there is no liquid in it, it's pure air. Using Co2, or compressed air adds liquid to the tire,throwing it off balance...makes sense to me.

I wanna get a Co2 tank only because I'm sorta impatient, with the slow speed of my $60.00 Comp. I bought from Pep Boys. :rolleyes:

My Bronco has an eletric OBA(Extreme Aire w/100% duty cycle) that does ok....with the 2 & 1/2 Gal. tank, But for just airing up my tires after a day of Wheeling my Sammy.

I'm seriously considering trying out a 10lb bottle ( Due to the Limited space in my Sammy) & seeing how much I like it..

I know it suppose to be about the fastest way to air your tires back up.

I dont plan on caring air tools in either of my rigs though..
Well maybe if I get all hardcore chaser dudehttp://bestsmileys.com/superhero/2.gif & such it might be helpful...

Perhaps there is some truth to that in asphalt racing where there are limited variables, but I find it difficult to believe that the condensation associated with a blast of cold air (or CO2) into a tire has much of a noticeable effect on the tire's balance. To put it into perspective, think about a couple droplets of water versus the weight and size of a desert tire and the imbalances introduced to it during the race such as mud, cactus spines, and torn-off lugs!

Here's an interesting read from a while ago on RDC about N2 vs CO2 for tire inflation http://www.race-dezert.com/forum/showthread.php?t=15444

Never heard the liquid balance theory before. I always thought it was just because Nitrogen doesnt change pressure as much with temperature change as compressed air. Nitrogen isnt exactly "pure air" but we know what you mean.

Thanks for the link, that was a great read! I'll be sticking with my Co2.

I had never heard that either, but it was mentioned by some in the thread that DaveG linked to.
