Nitrogen onboard air supply?

[orion_134]

I am looking into installing a nitrogen tank on my truck to run air tools, fill up tires, etc and I need some help brainstorming. I know I need a regulator to regulate it down, and all the guages, etc. The questions I have involve how a welding shop fills it up, how long it will last, and any dangers of it being back there.

I don't want to remove a tank every time I run out of air, do the welding shops just fill it up with a hose? IE, I can just put a fitting on the inside of the toolbox and can refill it that way instead of removing the tank?

Approx how long will a full tank last on a 3/8 impact ratchet?

Would I be better off putting a 10-15 gallon tank under my toolbox and hooking up an extremeair 12v compressor?

Thanks guys,
Jesse

It will proably depend on your supplier, I use nitrogen for my shocks. The tank was a must purchase item, they would not lease a 20# tank. When I need it filled they just exchange it. They should also have the regulator with the gauges on it, also a purchase item.

With any pressurized vessel there is danger. You can knock the valve off the end off the tank and create your own verison of the space shuttle. This could more easily happen if not secured to vehicle properly.

As for how long it will last, depends on how big of a tank you buy and what kind of use it will see.

If you already have the extremeair, then I would use it. If not, check into Osasis. They are more $, but will supply most with more air than they would ever need. I would rather have reserve and never need it, than to need it and not have it. A tank would be a must have with either compressor.

Hope this helps,
Greg

i have that on my pickup for my air horns and am gonna buy another for my towtruck.aint gonna run air tools off of it but should be perfect for flat tires and stuff.

i dont think id want a nitrogen tank strapped to my truck just for the fact that i have seen movies in school of what an acetylene or oxygen bottle does if you happen to knock the valve off of it

What your looking for is a Powertank (google it) or CO2 Tank, you can build one for $50.. The tank will have to be removed for refilling, because of a hazard with that much PSI... Plus it also HAS TO BE INSPECTED every so often.. you can set the tank up with a fire extinguisher holder and go that route so its mounted and movable... The CO2 in liquid form will last for a while depending on the LBS of tank you have.. The only issue that you will run into is the line freezing after a long period of use of using air tools.. I have a friend here that sells several differnt sizes of tanks and equipment, I will send a link and you can ask him questions


"15# co2 for $65 (filled 12 33" tires 8 31"tires 4 30" tires and resat a 31 to 35psi.)

Brackets for $30..... I'll have more and pics up this afternoon for everyone!!!

Co2 is stored in the cylinder at about 800psi in a liquid state. As vapor is used off of the top of the tank, liquid "boils off" and replaces the vapors.
A regulator is used to break the pressure down to a workable rate. Most are preset at 150psi but adjustable ones are available to move the pressure from about 5psi to 125psi(multiple uses )

Hoses can be bought at any hardware store(I like Northern) and run pretty cheap.

Air tools can be run by adding an in line oiler and a quick disconnect!

I like the idea of that 12v compressor, but how do you think it will work in a 10-15 gal tank? That is an awesome price too. I also need to check around and find out how much of a strain is put on the charging system when the compressor is on.
Thanks guys,
Jesse

That setup wont be able to power air tools very good, the air ratio isnt the best for the compressor to tank setup... It will be good for airing up tires though... Your best bet for tools and everything would be a CO2 tank

Look at it this way, with that setup your looking at with a compressor and tank, you have a 1 to 1 ratio and the compressor will struggle to maintain the pressure in the tank (wasted energy)

CO2 tank: the ratio is 1 to 860, (Liquid to Gas) you will have a constant supply of gasous O2 at any given psi that you want, its transferable and mobil

Nitrogen tank: ratio is 1 to 694, same as CO2 but its a cleaner, denser gas, this gas will not fluxuate like o2 does when it warms up (ie: tires) a little more expensive than O2 but it works...

That is true, but I also looking at it from a refill standpoint. Compare it blower vs. nitrous...you can get the same amount of power, the n2o will be cheaper initally, but eventually with all of the refills, it's cheaper in the longrun to get the blower i.e. the compressor setup.
Where did you come up with the ratios? I've never seen them compared like that. What do you mean the compressor doesn't match the tank?
Thanks,
Jesse

If you use a compressor you have to have a strorage tank to hold the air and to increase the volume... Im not understanding why you are mentioning a blower?

I work with liquid nitro and Liquid O2 with the fighter jets that I work on, and we are tought that info, plus if you google
liquid to gaseous ratios you can find it...

I was using that as a comparison between having to pay to refill the co2 and the refills getting costly (like n2o) and the compressor with a 10-15 gal tank would be cheaper in the long run for the same endstate (like a blower). I'm more into hi-po Mustangs, so it was an analogy I could understand.

im sure they make a bigger compressor than what i mentioned.dont know how ittl work with a 10-15 gallon tank.its rated for 100$ duty cycle at 100PSI at 70 degrees.but for what im gonna use it for it will be fine
