I think i want both. Viair 20007 is 179 right now on amazon. with remote kit and a check valve from granger. think i can make it work.link below. and get a tank from this place-link below- (20 lb) for 123 bucks, and have 2 ways to use air/C02. I will get Viair first. What do you guys think?

(added this -been reading the one it comes with fails)

So the regulator you linked would be the connection for the air line and gauge? I'm asking because I'd like the same setup but unsure how to build it.
 
i just seen a guy on youtube use that with no gauge , think i want a gauge
that regulator is pre set to 150 psi

Look into a Nitrogen tank, run it at 2500psi. Better than CO2 with more life between fill ups.
Also, make sure your local gas store will fill a personal tank. I'm not sure if it's CA wide, but I can't get any of my tanks refilled anymore. Or I think if I want to wait a couple days, they might take it to a filling station.

Wasn't always like that.
 
I run co2, much faster and if I remember correctly I can fill 14 42x14r16.5 tires from 4psi to 18psi with a 20lb tank. I got all my stuff from a soda machine place in town and fill them up at the place that sells weed growing supplies (I feel like a dirt bag going there but oh well). With co2, the pressure is affected more by temperature. So if I start when it's real cold out in the winter at 3 or 4psi, when it warms up I might be at 7 pounds or so. Just something to keep an eye on.
 
Nitrogen appears to be stored as a gas. (40 cubic feet in the tank listed)

CO2 is liquid in the tank (I assume why they, and propane tanks for instance, are measured by weight). It has far more volume than a same size tank of gas at 2500psi, which seems to be a pretty standard limit for air-type tanks. If nitrogen doesn't expand when released from the tank, it will have nowhere near the capacity, thus requiring a MUCH larger tank to get even close to CO2. A 20lb CO2 tank is ~175 cubic feet as gas. A 10lb CO2 tank is pretty handy, but a much less common size. I assume any gas vendor could get your tank refilled, but the 20# ones they will just one for one exchange. If the tank isn't stocked, I'm sure you will be waiting for refills.

I asked BFG direct if they were ok with CO2 used to inflate their tires, and they said no. Research I can find seems to indicate CO2 shouldn't hurt tires (although even compressed gas places have told me it's not good for rubber, the research I saw indicates it can leak out of tires much faster, which isn't really an issue from what I've experienced).

I've used CO2 for years now, but I don't put a ton of miles on my truck. That said, my BFG AT KO's are ~8 years old.

The problems I've found with CO2, or what I'd change if it was easily and cheaply accomplished, is how fast you can push air through the valve stem, and how high you can run the pressure. The regulator I've got won't let me get much past 120PSI. Fillup times aren't ridiculous with the 33's, but I'm still there a bit holding the chuck to the valve stem, which isn't a whole lot of fun when it's dark and raining or snowing.

Look on Craigslist. Grow operations and home brewers use these things, and you can get a tank and regulator setup for pretty cheap. I assume they'd be easy to resell if you decide you don't like it.

Every time I go to the local welding shop I feel like I got bent over when I fill bottles. Acetylene, oxygen, C02, nitrogen, I use all of them. Always seems like a ton of money for what I get. I do write off my gasses but it still pisses me off. For $180 on the viair you can fill your tires with free air for years to come. Once in a while compressed gasses would be fine I guess, but every time I air down my tires, no way, just throwing money away.
 
It's just the fill times.
I have a brand new York compressor, tank, and all the needed stuff in between. It's in a tote in the garage. I've kinda shied away from installing it. Dunno why, just have.
 
I think the last 20# CO2 fill (exchange) I got was $25. Prices are all over the map even in the same city. I calculated something like 10 total air ups (40 tires) from one bottle with my 33's, adding ~20PSI each.

A 10# bottle would be a fair bit handier than the #20 I have, but when dealing with compressed gases, you generally see greater economy the larger your bottle. It's pretty significant with the CO2/Argon mix I use, the 280 or 300CF bottle I use is massively cheaper by CF than the 80CF bottle I have. I don't see anything larger than 20# being practical in most situations though.

My Dad had the York setup on his truck, and it worked really well. No complaints with it, it is just a lot more (comparatively) complex to get going than a CO2 bottle, regulator, air hose, and tire chuck. But as mentioned, once you get it setup, you are pretty well done, no further expense. I think I got into my CO2 bottle and regulator for $80? With $25 fills, it will get expensive if you go through them all the time.

Click to expand...

You clearly need one(or two) of these... and cheap too :surepal:

Yes, it seems to be a lot cheaper to fill big bottles. My 10# nitrogen tank is sweet when I need to climb to a rooftop air conditioner but its like $50 to get it filled. My small torch is the same way. I try and use my bigger bottles when possible. CO2 is one of the cheaper gasses, nitrogen is more.
 
Wheres the one with four chucks? lol.

I guess at least with two, you can put your passenger to work.
 
There is a Vid on YouTube shows how to make those way cheaper than 200 bucks
 
I have a stock A/C compressor rigged to run my on board air.
Bought a little air compressor from Harbor Freight for the tank and regulator and check valve. Bought an air hose from them also. Really simple to operate really simple to make work. Have the air hose going to three places in the truck, one in the front one in the back and one of the side.

Will go with a York set up is this one ever dies and the extra two compressors I have don't work.

System works great at idle fills my 42's up rather fast. Think it cost me like $100 to build it.
I won an air tank at Blazer Bash, yeah kept my system.
